While most arrhythmias are benign, problems in the ventricular part of the heart can be serious and require treatment. The most devastating is ventricular fibrillation, which occurs when the normal steady heartbeat becomes a useless quivering of the heart. Defibrillators and pacemakers may be required in these cases. Arrhythmias may also be considered serious in any person who has previously had a heart attack. If you're experiencing any problem that has you worried, see your doctor.
