Overview
PSVT may be classified into several sub types based on underlying mechanism of tachycardia and ECG findings.
ECG findings include2 subtypes: Short PR interval tachycardia and long PR interval tachycardia.
Classification
- PSVT can be classified based on the underling mechanism and ECG findings.
- PSVT may be classified based on the underlying mechanism of tachycardia into [1]
- AV nodal reentry (AVNRT)
- AV reentry (AVRT)
- Atrial tachycardia
- Sinoatrial nodal reentrant tachycardia (SANRT)
- Intra atrial reentrant tachycardia (IART)
- Junctional ectopic tachycardia and nonparoxysmal junctional tachycardia (nonreentrent tachycardia, rare in adults, however represent a common cause of PSVT in children )
- PSVT may be classified based on the ECG appearance into:
