At First Flutter: Recognizing an Irregular Heart Rhythm
Next time you check your heart rate for optimal fat-burning potential during a workout, consider
checking your rhythm as well. Atrial fibrillation, also referred to as AF or A Fib, is a common
heart rhythm disorder that results in a flutter in the heartbeat caused by a problem in the upper
chambers, or atria, of the heart.
“While atrial fibrillation is not common among
young people, it can occur at any age,” says William Esper, D.O., an osteopathic cardiology
physician practicing in Erie, Pa. “However, the likelihood of developing the condition
increases with age.”
Those that suffer from atrial fibrillation have abnormal
electrical signals going to their atria. This abnormality causes the heart to quiver or fibrillate,
resulting in less oxygen-rich blood being pumped out. To date, more than 2 million people in the
United States have this disorder, but each year approximately 160,000 new cases are diagnosed.
According to Dr. Esper, almost 5 percent of people over age 65 and 9 percent of people 80 or older
suffer from atrial fibrillation.
“This disorder increases the risk of stroke
because it causes a pooling of blood in the atria, making a patient prone to blood clots moving
from the heart to vessels in the brain,” explains Dr. Esper.
The causes of atrial
fibrillation can include high blood pressure; coronary artery disease and prior heart attacks;
heart valve disease; and other medical conditions like overactive thyroid or lung disease.
Nonetheless, physicians occasionally diagnose patients without finding a definitive cause for the
condition at all.
“Avoid excessive alcohol if you consider yourself at
risk,” Dr. Esper warns. “Drinking an excessive amount of alcohol can cause episodes of
atrial fibrillation.”
The most extreme symptoms of this condition are acute chest
pains or fainting. More common warning signs include weakness, shortness of breath and fluttering of
the chest. However, since most people will not show any symptoms, Dr. Esper recommends that
everyone, particularly individuals more than 65 years old, check their heartbeat or pulse once a
month.
To take your pulse:
* Place the tips of your third and forth fingers on the
palm side of your other wrist, below the base of the thumb or on your lower neck on either side of
your windpipe.
* Find the blood pulsing beneath your fingers and count the beats you feel for
15 seconds.
* Multiply this number by four to get your heart rate per minute. The usual
resting heart rate for adults is
approximately 60 beats per minute.
A change in
the heart's rhythm may feel like an extra-strong heartbeat or a fluttering in your chest. If you
recognize an irregular rhythm, Dr. Esper recommends consulting your physician immediately. The
physician will then use an electrocardiogram (EKG or ECG) and a physical exam of the heart to
diagnose the disorder. If the patient has atrial fibrillation, there are many different methods of
treatment. According to Dr. Esper, medication is the most common method to control the irregular
heart rhythm.
“This condition can do serious damage to the heart and brain,
potentially resulting in a heart attack, heart failure and stroke if it is not diagnosed early
enough,” warns Dr. Esper. “The answer is early detection and treatment of atrial
fibrillation.”
Preventive medicine is just one aspect of care osteopathic
physicians (D.O.s) provide. Osteopathic physicians are fully-licensed to prescribe medicine and
practice in all specialty areas including surgery. D.O.s are trained to consider the health of the
whole person and use their hands to help diagnose and treat their patients.
