Some types of arrhythmias, such as ventricular tachycardia, are serious and even life threatening. In the United States, arrhythmias are the primary cause of sudden cardiac death, accounting for more than 350,000 deaths each year.
Types of Arrhythmias. There are two major types of arrhythmias. In tachycardia, the heart beats too quickly: more than 100 beats per minute. In bradycardia, the heart beats too slowly: less than 60 beats per minute. Tachycardias are classified by their location: Superventricular tachycardia (SVT) is the most common type of arrhythmia.
