Common Types of Arrhythmia

A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia.

Atrial Fibrillation (A-Fib)

Atrial Fibrillation is a rapid, irregular heart rhythm originating in the atria that can cause symptoms such as palpitations, rapid heartbeat, chest discomfort, shortness of breath and dizziness. In some individuals, atrial fibrillation increases the risk of stroke.

Ventricular fibrillation

Ventrical fibrillation can result in an arrhythmia that originates in the pumping chambers, or ventricles, and usually occurs in people who have a damaged heart. Damaged hearts can be the result of a heart attack or structural abnormalities, like an enlarged heart. Because ventricular fibrillation is so rapid and is occurring in a damaged heart, the heart may not function properly or efficiently, and this arrhythmia can be fatal.

AV Node Re-entry Tachycardia

AV Node Re-entry Tachycardia is a rapid heart rhythm and the most common form of paroxysmal supraventricular tachycardia or PSVT, also referred to as SVT. Patients with this arrhythmia do not have structural problems with their heart, but have two pathways that can channel impulses to and from the AV node. Under certain conditions, usually following a premature beat, these pathways can form an electrical circuit, which starts a rapid (over 100 beats per minute) heart rhythm.

Wolffe-Parkinson-White Syndrome

Wolffe-Parkinson-White Syndrome is an arrhythmia caused by an extra electrical pathway from the atria to the ventricles. Although some people with WPW do not have any symptoms, others include experience palpitations, dizziness, and chest discomfort. Rarely, WPW can be life threatening.
