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

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 & 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, which can contribute to

Don’t Miss The His ®️ I EP Lab Education on Instagram: "AVNRT: AV Nodal Reentrant Tachycardia One of the key signs: fusion of the V and A! Just to be specific remember we can’t really tell it’s going THROUGH the AV NODE. The reentrant circuit is conducting AROUND the AV NODE! But knowing when it’s that fast and close together it’s likely AVNRT! #electrophysiology #epeeps #eplab #hrs2025 #heart #heartrhythm #arrhythmia"

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*:
