Types of Arrhythmia. There are many types of arrhythmias. Arrhythmias are identified by where they occur in the heart (in the atria or ventricles) and by what happens to the heart's rhythm when they occur. Arrhythmias that begin in the atria are called atrial or supraventricular (above the ventricles) arrhythmias. Ventricular arrhythmias begin in the ventricles. In general, ventricular arrhythmias caused by heart disease are the most serious. Premature beats are the most common type of heart arrhythmia.
