Introduction
- reentrant circuit in which the impulse travels anterogradely from the atrium to the ventricle via an accessory pathway * returns retrogradely to the atrium via the AV node (or, rarely, a second accessory pathway)
Diagnostic procedures
Differential diagnosis
- orthodromic atrioventricular reciprocating tachycardia (AVRT)
- narrow QRS complex tachycardia
- atrial fibrillation with aberrant conduction
- diabetes mellitus risk factor
- wide complex irregular tachycardia follows single sinus beat in MKSAP20 ECG[2]
- absence of p waves (questionable in MKSAP20 ECG)[2]
