Orthodromic vs. Antidromic AVRT: The Loop Determines the QRS In AVRT, the circuit includes both the native conduction system and an accessory pathway (AP). The direction of impulse travel dictates the ECG morphology. 🔁 Orthodromic AVRT (Narrow QRS) • Down: AV node → His-Purkinje system (normal ventricular activation). • Back: Retrograde via the AP to the atria. • ECG: Narrow complex (unless aberrancy). ⚡ Antidromic AVRT (Wide QRS) • Down: AP directly into the ventricle (pre-excitation). • Back:

Mistaken for V-tach, but it's antidromic AVRT! ECG analysis showing wide QRS complexes. Avoid calcium channel blockers; opt for cardioversion. #ECG #Cardiology #MedicalEducation #AVRT #VTach
