What causes irregular heart beat? – Learn about heart disease.
Here’s another question I asked Dr. Cynthia Shelby-Lane and her answer about causes irregular heart beat.
Lisa Nelson: What do you recommend for individuals experiencing heart palpitations and what may be triggering the problem?
Dr. Shelby-Lane: Arrhythmias are any deviations in the normal rhythm of the heart (heartbeat). They usually occur as a result of interference with the electrical pathways that produce the heart’s rhythmic muscular contractions. The Parasympathetic Nervous System is responsible for slowing down the heartbeat rate. The Beta-1 Adrenergic Receptors of the Beta-Adrenergic Nervous System are responsible for speeding up the heartbeat rate.
If you experience the following symptoms, you may need to be evaluated for toxicity and consider a stress test, echocardiogram, holter monitor or a tilt table test for further evaluation and diagnosis. A neurologic evaluation may also be indicated.
Fluttering or pounding in the heart
Hemodynamic disturbances are potentially life-threatening such as bradycardia and tachycardia
Dizziness
Syncope (fainting)
Unusual awareness of the heart
Anxiety
Abnormal ECG (provides a “one-shot” picture of the electrical activity of the heart)
Holter 24-hour monitoring results (Holter monitors look at the heart for a longer period of time and are necessary to detect intermittent rhythm problems.
Possible Causes Irregular Heart Beat, Contributing or Associated Factors
1. Coronary artery disease
2. Hypertension
3. Adverse drug reactions
4. Endocrine imbalances, especially thyroid or adrenal disorders
5. Myocardial tissue disease (valvular, atrial and ventricular abnormalities)
6. Sequela of rheumatic fever
7. Metabolic disorders
8. Nutritional deficiencies, especially magnesium
9. Caffeine
10. Environmental toxins or food allergies
11. Damaged conductive tissue (neurocardiogenic syncope)
12. toxicities
13. anxiety and stress disorders, etc.
Follow up diagnostic testing is recommended to determine if the above conditions are causing the problem.
Heart disturbances can occur as a symptom of magnesium deficiency: Measuring your red blood cell magnesium can give you a good idea of your actual magnesium level.

Heart Healthy Tips
Weight Loss – How Stress and Cortisol Affect Weight Loss
Do you struggle with extra fat around your midsection? Excess abdominal fat is not only visually unappealing to some, but it increases your heart disease risk.
What causes abdominal obesity?
There are many different reasons your body likes to store fat in the abdomen. I want to discuss one possibility – cortisol.Cortisol is a hormone made by the adrenal glands in the kidney. Cortisol levels are highest in the morning. Through gluconeogeneis (term for glucose production), cortisol breaks down muscle to provide the body with needed glucose for energy needs. Cortisol also relocates fat cell deposits into the visceral cavities of the abdomen.
When we are confronted with stress our body’s initial response is “fight or flight”. When we go into “fight” mode our body releases the hormone norepinephrine. When we respond with “flight” (or anxiety) our body releases epinephrine. If the stressful situation is long term and you begin to feel distressed and defeated, the hypothalamus in the brain becomes involved, eventually leading to the release of cortisol from the adrenal gland in the kidney.
Why is “fight or flight” important to understand?
Your perception of an event can determine your body’s physical response. Do you feel stressed, but challenged by an obstacle or do you feel overwhelmed and out of control? If you feel challenged and “fight” your body responds with an accelerated heart rate that increases the release of fatty acids into circulation. If you feel out of control and defeated (“flight”), the body increases fat formation (lipogenesis), breakdowns tissue (muscle), suppresses the immune system, and increases visceral fat deposits.
What is visceral fat?
Visceral fat is the fat around and between your organs. Subcutaneous fat is the fat layer beneath your skin.
Excess visceral fat leads to the “beer belly” effect (also referred to as the “apple” shape). Visceral fat is connected to insulin resistance and glucose intolerance (linked to diabetes), high cholesterol, high blood pressure, and heart disease.
Are you at risk?
Get out a tape measure.
Wrap the tape measure around your abdomen at the level of your navel (belly button). Make sure the tape measure is level all the way around (you may need extra hands). Resist the temptation to cinch in the tape measure for a lower number, instead hold the tape measure lightly against your skin.
Men – A waist measurement of 40 inches (102 cm) or greater equal’s abdominal obesity.
Women – A waist measurement of 35 inches (88 cm) or greater equal’s abdominal obesity.
How to reduce stress for minimal impact on abdominal fat and heart disease risk?
Stress is a part of living, but you can take steps to reduce your stress levels.
Physical activity, especially aerobic activity, is a great stress management tool. Activity releases the “feel good” hormone serotonin to help combat the negative effects of long term stress. As an added bonus, you burn calories to shed the extra layer of fat.
p>Additional interventions to reduce stress include deep breathing, progressive relaxation, meditation, and visualization. Don’t be afraid to step out of your comfort zone and try something new that may be effective at reducing your stress levels. Getting enough sleep and making healthy food choices are two additional steps to promote stress management.

Blood Pressure and Cholesterol – The Affect of Personality and Panic Attacks
Lisa Nelson RD: What role does personality play in a person’s heart disease risk? Does temperament have a direct affect on cholesterol levels or blood pressure?
Dr. Shelby-Lane: Temperament and personality have a definite effect on blood pressure and on heart disease. This is a great question and it has been studied by the experts, as you will note in the following excerpts. Heart disease consists of congenital abnormalities, arrhythmias, lipid abnormalities acquired and congenital, functional and physiologic problems, risk factors such as diabetes and metabolic syndrome, structural disease and valvular problems, heart failure, acquired disease such as coronary artery disuse, and infectious diseases along with diseases related to blood vessel structure. Again, anxiety, stress, and stress related disorders can have an effect on major hormones, heart rate and heart health and heart disease. Nutritional abnormalities can also affect heart performance.
New research suggests that people who suffer from panic attacks are at increased risk of developing heart disease.
Dr Kate Walters and colleagues at University College London examined medical records of more than 400,000 people, including 57,615 who had been diagnosed with panic attacks. Results showed that people who were younger than 50 when they were first diagnosed with panic attack were 38% more likely to have a heart attack and 44% more likely to develop heart disease than those without the condition. Those who were older than 50 at the time of diagnosis did not have an increased risk of heart attack, but were 11% more likely to develop heart disease than those without the condition.
Intriguingly, the results also showed that while panic attack sufferers were at increased risk of developing heart disease, they were seemingly less likely to die from it.
Why people who suffer from panic attacks should be at increased risk of developing heart disease is unclear. According to the study, authors put forward several theories, one being that panic disorders might trigger nervous system changes which could promote the clogging of arteries. Another theory is that people may have been misdiagnosed as having panic attacks when they actually have coronary heart disease. “Clinicians should be vigilant for this possibility when diagnosing and treating people presenting with symptoms of panic,” said Dr Walters.

News release: Panic attacks linked to higher risk of heart attacks and heart disease, especially in younger people. European Society of Cardiology. December 10th 2008.
Study results have shown that people with depression are at increased risk of heart attack and heart failure because they are less likely to be active.
Scientists have known for some years that people who are depressed are at increased risk of heart attack and other cardiac events, however the reason why this should be has remained unclear. However, according to results of a study by Mary A Wooley and colleagues, the increased risk is due to behavioral factors.
The researchers analyzed data obtained from 1,017 people with heart disease, 199 of which had symptoms of depression. Results showed that 10% of depressed participants had a cardiac event (e.g. heart attack, heart failure, stroke, transient ischemic attack) during the study period, compared to just 6.7% of non-depressed participants, meaning that depressed participants were 50% more likely to have a cardiac event. However, results also showed that depressed participants were more likely to smoke, were less likely to take their medications as prescribed, and were less physically active. After the researchers factored these behaviors into their calculations the risk of a cardiac event in depressed participants was similar to that in non-depressed participants.
The researchers concluded: “These findings raise the hypothesis that the increased risk of cardiovascular events associated with depression could potentially be preventable with behavior modification, especially exercise.” Adding: “Exercise training can improve both depressive symptoms and markers for cardiovascular risk.”

Be Heart Healthy and Lose Weight
Want more respect?
Overcoming stress is one positive step towards heart health and weight loss. Here’s a guest post from Doris Helge, Ph.D. She provides a simple technique for gaining more respect so you can get your needs met and enjoy your life much more. Turn anger, fear, and other negative emotions into peace and confidence.
Want more respect?
by Doris Helge, Ph.D.
Even though Jan and Nan are both very talented, Jan’s contributions are applauded while Nan’s gifts are unnoticed. What’s Jan’s secret? Jan has discovered that we are constantly training other people how to treat us. When Jan is treated with disrespect, she politely says, “No thank you” by using the technique in this article. Even though Jan knows we can’t change other people, she knows how to set up situations in which she’s treated well and her needs are met.
The following is an example of how you can gain peace of mind when someone else’s behavior rubs you the wrong way. My coaching clients call it The Get Respect Now Technique.
DON’T BE AN OSTRICH
Nan tries to ignore her problems like an ostrich that hides its head in the sand. Then Nan moans that life presents her with the same snarly packages over and over. Jan’s approach is very different. She meets a challenge with, “Hmmm . . . I wonder what I’ll learn from this experience?” Denying an unpleasant situation breeds more of the same. The challenge magnifies until we finally say, “Alright, already . . . I’ll deal with this.” Avoid getting hit over the head by a 2×4 by standing up for yourself when a toothpick jabs you. Perceive situations as accurately as possible. A rope is a rope and a snake is a snake. The simple act of acknowledging what exists initiates the potential for positive change. Why? You signal your mind to search for solutions.
AIM FOR RESULTS INSTEAD OF TRYING TO BE “RIGHT.”
When you’ve been treated with disrespect, pause a moment and ponder. How can you express what you’re entitled to in a factual way? The other person may never acknowledge that you’re right because all of us have erroneous perceptions. They’ve been formed by decades of experiences and faulty beliefs.
Do you ever watch a “sunset” even though the sun never sets? Do you ever instantly like or dislike a person you’ve never met? When treated with disregard, your goal is to be heard and get your needs met. We can’t force other adults to change their opinions or behavior. However, we are in total control of how we respond to every situation. We can say what we need to and transform anxiety into peace of mind.
EXAMPLES
Here’s an example you might use at work. “I felt hurt when his contributions were recognized and mine weren’t noticed. I need for my work to be acknowledged.” An example at home is, “When you didn’t call and tell me you changed your plans, I worried about you. I need to know when you’ll be late so I can arrange my own schedule.” Notice: These statements are not drenched with negative emotions or accusations that trigger defensiveness and counter attacks. You gain positive results faster by using “I statements” that acknowledge your emotions. Use the minimum amount of words possible to say what you need. Know you deserve it. This approach will empower you to breathe a big sigh of relief and go on with your next step in life.
THE FINAL OUTCOME
No matter what the final outcome of the particular situation, you’ll meet your personal growth challenge, so this type of situation will occur less frequently. Just use the technique I’ve outlined so you can easily resolve conflicts with “difficult people.” Soon, an effective response to disrespectful behavior will become easy and automatic because you’ll be clear what you deserve. Enjoy knowing you are so powerful that you can infinitely reshape your life. You deserve happiness. Turn every unpleasant experience into a rich opportunity for personal growth.

Achieve a work-life balance for your health!
I have teamed up this month with Joy on the Job expert Doris Helge, Ph.D. Part of living a healthy life is maintaining a balance between your work and your life. When you don’t meet your needs, your work quality, your relationships and your health deteriorate. Everyone loses when you fail to set healthy boundaries and practice the art of compassionate assertiveness so you can enjoy the work-life balance you deserve.
In this guest post from Doris, you’ll learn how to say “no thank you” to what you don’t want and “YES!” to what you do want. Enjoy! Lisa Nelson, RD, LN
Say “YES” to Work-Life Balance
by Doris Helge, Ph.D. © 2008
A client I’ll call Jenny called me in tears. “I have no work-life balance. The people I work with want everything instantly. My husband wants credit when he helps out with the kids . . . as if he isn’t also 50 percent responsible for them! To me, work-life balance isn’t a luxury. It’s essential. If I can’t get some quality time for myself, I’ll be no good to anyone at work or at home.”
Do you sometimes feel like a puppet whose strings are pulled up, down, right, and left at the same time? Ouch!
It’s time to set boundaries and practice the art of compassionate assertiveness. Then you can enjoy the work-life balance you deserve.
YOU ALREADY HAVE THE POWER TO DEVELOP WORK-LIFE BALANCE
No matter what you’ve been told, you are in charge of your own life. You are the only person who can say with conviction, “Wait a minute please. I’m busy right now. As soon as I finish doing ______, I will give you my full attention.”
You are the sole individual who can identify your needs and establish healthy boundaries. You are also the only person on this planet who can maintain your personal boundaries without feeling guilty.
That’s personal power! We’re all very powerful people with a vast array of capabilities. Some of us have forgotten how to be assertive about our own needs. You may think that only harms the person who doesn’t stand up for themselves. Unfortunately, that’s not true. When you don’t say “No” to what you know isn’t right for you, you set a powerful negative ripple effect in motion.
EVERYONE LOSES WHEN YOU GIVE AWAY YOUR INNATE POWER
If you don’t set and maintain personal boundaries, everyone around you suffers. In fact, a nasty chain effect rumbles forward like a runaway train. Because you resent the fact that your needs aren’t met, you radiate an energy of, “I’m a victim.” The people around you react in a variety of ways. Here are some examples.
- Some people will become defensive about their behavior. They may even feel manipulated. Neither reaction will help you resolve the core issue.
- When you play the role of victim, other people rush forward to play the role of bully. They act like wild animals stalking a wounded prey.
- Some people become angry or frustrated when you don’t feel strong enough to say “No thank you” regarding what you don’t want, in a kind assertive manner. They develop a negative opinion about your ability to perform well in the future.
- Some people gather around you and commiserate about your sad situation. You may temporarily feel validated when surrounded by supporters. However, these are dangerous cheerleaders because your circumstances don’t improve when you reinforce the belief, “I’m a victim.”
- If you play the role of martyr, other people will follow your example. Whether you like it or not, you are always a role model for someone.
This brings us back to your personal power. Look at your impact on the lives of other people in the above examples. Since you can affect the thoughts, emotions, and behaviors of the above people in such a significant way, how can you possibly feel like a victim of life?
TRANSFORM YOUR PAIN INTO POWER
Another choice is to set the intention of walking beyond your fear of change so you can become the confident, capable person you are destined to become. What’s the worst that can happen if you take a small step toward your true self?
Make a decision to enjoy the work-life balance you need and deserve today. Each time you say “No thank you” to what you don’t want, you send a clear signal to the universe saying, “YES!” to what you do want.
