The four main types of arrhythmia are premature (extra) beats, supraventricular (SU-prah-ven-TRIK-yu-lar) arrhythmias, ventricular arrhythmias, and bradyarrhythmias (bray-de-ah-RITH-me-ahs). Premature beats are the most common type of arrhythmia. They're harmless most of the time and often don't cause any symptoms. When symptoms do occur, they usually feel like fluttering in the chest or a feeling of a skipped heartbeat. Most of the time, premature beats need no treatment, especially in healthy people.
There are only slight differences between these arrhythmias. slide 1 of 5. About Arrhythmias An arrhythmia is an abnormal heart beat. Two groups of arrhythmia are bradycardia and tachycardia. Bradycardia is a heart rate slower than 60 beats per minute (bpm). Tachycardia is a heart rate faster than 100 bpm. Two forms of tachycardia are sinus tachycardia and supraventricular tachycardia. There is little difference between supraventricular tachycardia and sinus tachycardia.
