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.
Palpitations can also result from a range of heart arrhythmias. These are classified by location, and type of heartbeat. A few common types: Supraventricular tachycardia â A rapid heart rate originating above the ventricles (lower heart chambers). It can cause the heart to beat very quickly or erratically.
