Supra ventricular tachycardia

Supraventricular tachycardia (SVT) is an abnormal heart rhythm arising from improper electrical activity of the heart. It is a type of rapid heart rhythm originating at or above the atrioventricular node. It can be contrasted with the potentially more dangerousventricular tachycardias—rapid rhythms that originate within the ventricular tissue.

Although SVT can be due to any supraventricular cause, the term usually refers to a specific example, paroxysmal supraventricular tachycardia (PSVT), two common types being atrioventricular reentrant tachycardia and AV nodal reentrant tachycardia. In the older population atrial fibrillation becomes a common type of supraventricular arrhythmias—though it is typically considered separately.

In general, SVT is caused by one of two mechanisms: re-entry and automaticity. Re-entry (such as AV nodal reentrant tachycardia and atrioventricular reciprocating tachycardia) often presents with an almost immediate increase in heart rate. Someone experiencing this type of PSVT may feel the heart rate accelerate from 60 to 200 beats per minute or more. Typically, it reverts to normal just as suddenly.

In "automaticity" types of SVT (atrial tachycardia, junctional ectopic tachycardia), there is more typically a gradual increase and decrease in the heart rate. These are due to an area in the heart that generates its own electrical signal.
