Millions of people experience irregular or abnormal heartbeats, called arrhythmias, at some point in their lives. Most of the time, they are harmless and happen in healthy people free of heart disease. However, some abnormal heart rhythms can be serious or even deadly. Having other types of heart disease can also increase the risk of arrhythmias.

Electrical: Abnormal heart rhythms (arrhythmias) are caused by problems with the electrical system that regulates the steady heartbeat. The heart rate may be too slow or too fast; it may stay steady or become chaotic (irregular and disorganized). Some arrhythmias are very dangerous and cause sudden cardiac death, while others may be bothersome but not life threatening.

Circulatory: High Blood Pressure and coronary artery disease (causing blockages in the pipes (arteries) that supply blood to the heart) are the main causes of blood vessel disorders. They can result in a stroke or heart attack, which can be devastating. Fortunately, there are many preventative and treatment options.

Structural: Heart muscle disease (cardiomyopathy) and congenital abnormalities (problems in the development of the heart and blood vessels which are present from birth) are two problems that can damage the heart muscle or valves.

Ventricular Tachycardia (VT)A life-threatening arrhythmia, ventricular tachycardia is usually seen along with other serious heart disease but sometimes happens in people with normal hearts. Because VT can lead to ventricular fibrillation (a dangerously fast and disorganized heartbeat), it is a serious condition that needs aggressive treatment and follow up.

Treatment options include surgery, radiofrequency ablation (scarring or burning the area of heart tissue that triggers the abnormal rhythm), and/or medication. People with VT are often protected by a defibrillator (a device that can shock the heart out of the dangerous heartbeat) that is implanted in the body.
