The TAH replaces the lower chambers of the heart, called ventricles. Tubes connect the TAH to a power source that is outside the body. The TAH then pumps blood through the heart’s major artery to the lungs and the rest of the body.

Typically doctors screen for atrial fibrillation only when you have symptoms. However, your doctor may check for signs of atrial fibrillation as part of your regular medical care. Screening tests include checking your pulse or recording your heart’s electrical activity.

Many factors play a role in preparing your body to fall asleep and wake up. Your body has several internal clocks, called circadian clocks.

Arrhythmia is caused by changes to heart tissue. It can also occur suddenly as a result of exertion or stress, imbalances in the blood, medicines, or problems with electrical signals in the heart. Typically, an arrhythmia is set off by a trigger, and the irregular heartbeat can continue if there is a problem in the heart. Sometimes the cause of an arrhythmia is unknown.

Your doctor may recommend cardiac catheterization to find out what is causing signs or symptoms of a heart problem or to treat or repair a heart problem.

Sometimes VTE does not cause symptoms until serious complications occur. In other cases, deep vein thrombosis causes swelling or discomfort near the blood clot. Pulmonary embolism can cause chest pain and difficulty breathing. Pulmonary embolism can be a life-threatening condition.
