Can You Exercise With Tachycardia?
A resting heart rate between 60 and 100 beats per minute (bpm) is considered normal for most people, according to the American Heart Association (AHA). If your resting heart rate is over 100 bpm, you have a type of arrhythmia, or abnormal heart rate, called tachycardia.
It's normal for your heart to beat faster when you exercise. But lots of things can set your heart racing even while you're at rest. Tachycardia can be a response to stress or anxiety, fever, caffeine, or certain medications, according to the AHA. Or it might be due to a health condition, such as hyperthyroidism or heart tissue damage.
Tachycardia simply means there is some disruption in the normal electrical impulses controlling the heart's pumping action, according to Mayo Clinic. Although it doesn't always cause symptoms, the most common is a noticeably faster heart beat, or palpitations. You might also experience shortness of breath, dizziness, lightheadedness, fainting, or chest pain.
Treatment depends on the type of tachycardia you have and can include medication and certain procedures. In extreme cases, tachycardia that's left untreated can cause complications that lead to sudden cardiac arrest, according to Cleveland Clinic.
However, most people with a heart rhythm problem can continue to live normal lives. In fact, that may mean adopting certain healthy lifestyle changes, such as becoming physically active.
A key consideration before beginning any exercise program is to determine the type of activity best suited for an individual's personal health situation.
“Anyone with tachycardia should see a physician for clearance before exercising,” says Steven Reisman, MD, director of the New York Cardiac Diagnostic Center in New York City.
Working with your doctor will help you determine if there is an underlying condition, such as anemia or an overactive thyroid, that's causing the arrhythmia, Dr. Reisman says. It's possible that the arrhythmia is part of the heart's normal process, but a thorough examination will confirm whether the tachycardia poses a risk of more serious health problems.
“An evaluation should be done, including blood tests, EKG [electrocardiogram], and possibly other heart tests, to rule out any abnormal condition,” Reisman says.
“Once cleared by the physician, it would then be okay to exercise as long as the individual does not have symptoms such as chest pain, shortness of breath, or dizziness while exercising,” he says. If any of these symptoms occur, stop the activity and seek medical attention if they do not resolve with rest.
Exercising for 150 minutes a week — 30 minutes five days a week, for instance — is the recommendation of the Office of Disease Prevention and Health Promotion and the AHA.
Incorporating regular doses of physical activity into each day will help you feel better physically and mentally. Even if you can't do all 150 minutes a week right away, take small steps and increase activity as you progress. Park a little farther away from the entrance of stores where you shop. Take the stairs instead of using the elevator. Meet a friend to walk around the mall or a local park. You don't have to run a marathon to be moving toward good health.
Remember that exercise comes in all types of packages. You have options in a variety of settings — the gym, a yoga or barre studio, trails at the park, or the sidewalk in your own neighborhood. Brisk walking, swimming, and bicycling are potential options, Reisman says.
Talk with your doctor to confirm your maximum heart rate and your target heart rate, which ranges between 50 and 85 percent of the maximum rate, according to the AHA.
“One formula to determine 100 percent of maximal heart rate is age-dependent,” Reisman says. The formula looks like this: 220 ‒ your age = maximum target heart rate in beats per minute. For example, for a 50-year-old, it would be 220 – 50 = 170 bpm. From that number, you'd calculate your target range, in this case between 85 and 144 bpm. However, he says, “This is only a rough guide and must be individualized depending on the physical condition of the person.”
The type of exercise that’s best for you may depend, in part, on the type of arrhythmia you have. You might have to take more care than others to prevent undo stress on the heart, but that doesn't mean you should avoid physical activity. Cardio exercises, yoga, and gentle stretches are typically great options, according to the Oklahoma Heart Hospital in Oklahoma City. Just be sure to speak with your doctor to come up with an appropriate plan to help you stay physically active.
