cardioBeat on Instagram: "AVNRT & Ablation Targets Atrioventricular Nodal Reentrant Tachycardia (AVNRT) is a common type of supraventricular tachycardia characterized by reentry within or around the AV node. Understanding the pathways and ablation targets is crucial for effective treatment. 1⃣ Slow-Fast Pathway: Right Inferior Extension: Ablation targets the slow pathway located at the right inferior extension of the AV node. Left Inferior Extension: Another target is the left inferior extension

ECG on Instagram: "Atrioventricular Nodal Reentrant Tachycardia (AVNRT) – Summary & Treatment 🔹 Definition: AVNRT (Atrioventricular Nodal Reentrant Tachycardia) is the most common type of PSVT, caused by a reentrant circuit within the AV node, leading to a rapid, regular narrow-complex tachycardia. --- 🔹 Pathophysiology: The AV node has dual conduction pathways: ✅ Slow pathway (short refractory period) ✅ Fast pathway (long refractory period) A premature atrial beat (PAC) can trigger a reentran
