Arrhythmias are characterized by their site of origin:  the atria or the ventricles. Supraventricular arrhythmias occur in the upper areas of the heart and are less serious than ventricular arrhythmias. Ventricular fibrillation is the most serious arrhythmia and is fatal unless medical help is immediate.
