The right amount of sleep helps prevent arrhythmias by lowering your stress level or making it easier to lose weight. It also keeps you from feeling fatigued, which Erica notes can sometimes trigger an arrhythmia. Aim to get about seven to nine hours per night.
Getting enough sleep is even more important if you have sleep apnea—a disorder where your breathing is interrupted during sleep. In addition to watching your diet, exercising and getting enough sleep, Erica recommends making several lifestyle changes to keep your arrhythmia in check:. You can certainly live a happy, healthy life with an abnormal health rhythm.
However, it's always a good idea to check with your doctor when you're experiencing new symptoms or discomfort. This slight delay allows the ventricles to fill with blood. When electrical impulses reach the muscles of the ventricles, they contract, causing them to pump blood either to the lungs or to the rest of the body.
When anything disrupts this complex system, it can cause the heart to beat too fast tachycardia , too slow bradycardia or with an irregular rhythm. Any condition that puts a strain on the heart or damages heart tissue can increase your risk of ventricular tachycardia. Lifestyle changes or medical treatment may decrease the risk associated with the following factors:. If you have a family history of ventricular tachycardia or other heart rhythm disorders, you may have an increased risk of ventricular tachycardia.
Complications of ventricular tachycardia vary in severity and depend on how fast your heart is beating, how long the rapid heartbeat lasts, how often tachycardia occurs and your overall heart health.
Possible complications include:. A dangerous condition related to ventricular tachycardia is ventricular fibrillation V-fib. In V-fib , your lower heart chambers contract in a very rapid and uncoordinated manner.
This abnormal rhythm happens most often in people with heart disease or a prior heart attack. It may also occur due to electrolyte problems such as high or low potassium levels or, rarely, in otherwise normal hearts. Ventricular fibrillation may also cause sudden cardiac arrest and lead to death if not treated immediately.
The best way to prevent ventricular tachycardia is to treat or eliminate risk factors that may lead to heart disease. If you already have heart disease, follow your treatment plan and a heart-healthy lifestyle. Ventricular tachycardia care at Mayo Clinic.

Healthy, older adults free of heart disease need not fear that bouts of rapid, irregular heartbeats brought on by vigorous exercise might increase short- or long-term risk of dying or having a heart attack, according to a report by heart experts at Johns Hopkins and the U. Researchers say such fears surfaced after previous studies found that episodes of errant heart rhythms, more formally known as non-sustained ventricular tachycardia, more than double the chance of sudden death in people who have already suffered a heart attack.
In a study to be presented Nov. In adults with no earlier signs of heart disease, researchers found no adverse effects resulting from brief episodes of exercise-induced ventricular tachycardia. In the study, each volunteer participant had a least one exercise stress test performed before The test assesses the heart's pumping ability, requiring participants, whose average age at testing was 52, to walk or jog on a treadmill at increasing speeds and inclines until they felt exhausted, about 10 minutes for most.
Eighty-one roughly 4 percent, 65 men and 16 women, mostly older participants experienced short periods of rapid, irregular heartbeats during exercise, typically lasting from three to six heartbeats, and at a rate hovering around beats per minute.
Researchers say overall death rates were higher in the tachycardia group than in the nontachycardia group at 29 percent and 16 percent, respectively.
