Cardiac arrhythmia is a group of conditions where the heartbeat is irregular, too slow, or too fast. The main types of arrhythmia are bradycardias, extra beats, supraventricular arrhythmias, and ventricular arrhythmias. Supraventricular arrhythmias include atrial fibrillation, atrial flutter, and paroxysmal supraventricular tachycardia. Ventricular arrhythmias are ventricular fibrillation and ventricular tachycardia. Extra beats include premature atrial contractions, premature ventricular contractions and premature junctional contractions.
Arrhythmias are caused by the problems with the electrical conduction system of the heart. Some types of arrhythmia are not serious, some can lead to life-threatening complications such as stroke, heart failure, or sudden cardiac arrest.
