Atrioventricular Nodal Reentrant Tachycardia (AVNRT): Mechanism & Management 🔹 Primary Mechanism & Ablation Target AVNRT is a macro-reentrant supraventricular tachycardia dependent on dual atrioventricular (AV) nodal physiology. The typical (slow-fast) circuit uses the slow pathway for antegrade conduction and the fast pathway for retrograde conduction. Catheter ablation targeting the slow pathway is the definitive therapy. The standard anatomical target is the right inferior nodal extension wi

AVNRT vs. AVRT: AVNRT: Microreentry within the AV node. · ECG: Short RP interval. P wave typically buried (pseudo R' V1). · Baseline: No pre-excitation. AVRT: Macroeentry utilizing an accessory pathway. · ECG: Long RP interval. Discrete retrograde P wave in ST segment. · Baseline: Often exhibits pre-excitation (WPW pattern). Critical: Pre-excited AF requires avoidance of nodal blockade. Like ✅ | Share 🔁 | Comment 💬 #Cardiology #Electrophysiology #SVT #ECG #HeartRhythm | Abdallah Othman

AVNRT (Atrioventricular Nodal Reentrant Tachycardia) and AVRT (Atrioventricular Reentrant Tachycardia). #Cardiology #Healthcare Overview: AVNRT and AVRT are types of supraventricular tachycardias (SVTs) characterized by re-entry circuits involving different pathways. AVNRT involves the AV node, while AVRT involves an accessory pathway between the atria and ventricles. - AVNRT Etiology*: Re-entry circuit within or around the AV node. - AVRT Etiology*: Presence of an accessory pathway. Diagnosis*:

AV Node Physiology: Fast vs. Slow Pathways 🐇🐢 The AV node’s fast and slow pathways are pivotal in arrhythmogenesis, especially in conditions like AVNRT. This clip from our latest YouTube video offers a quick refresher on the physiology behind these pathways, setting the groundwork for recognizing AVNRT subtypes. 👉 Watch our full YouTube video for a detailed breakdown of fast-slow, slow-fast, and slow-slow AVNRT patterns and pathways here: https://youtu.be/wtDzo9zihSE Thank you to Matt from @s
