ECG on Instagram: "❗️Beauty of Cardiology ✨ | Adenosine & PSVT ➡️Adenosine is one of the most elegant tools in cardiology. With a brief, transient AV nodal block, it can instantly terminate AV node–dependent PSVTs, especially AVNRT and orthodromic AVRT. 🔶️In just a few seconds, the tachycardia stops — or the underlying rhythm is revealed.

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:

Abdallah Othman on Instagram: "Atrioventricular Reentrant Tachycardia (AVRT) ✨(AVRT) is a type of supraventricular tachycardia (SVT) caused by a reentrant circuit involving the AV node and an accessory pathway (AP). Pathophysiology - Reentry circuit: AV node + accessory pathway (AP). - Orthodromic (90%): Narrow QRS ➡️ AP retrograde. - Antidromic (10%): Wide QRS ⚠️ (mimics VT). 📈 ECG Signs: - Orthodromic: Retrograde P wave after QRS, ❌ delta wave during tachycardia. - Antidromic: Wide QRS, delta
