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

🔁 AVRT Quick Visual Guide. 1️⃣ Orthodromic AVRT (Most Common): → Pathway: Antegrade AV node ➡️ Retrograde accessory pathway. → ECG: Narrow QRS, retrograde P waves (RP > PR). → Key: Classic in WPW syndrome. 2️⃣ Antidromic AVRT (Rare): → Pathway: Antegrade accessory pathway ➡️ Retrograde AV node. → ECG: Wide QRS (mimics VT), retrograde P waves (often buried). → Key: Riskier due to preexcitation. #Cardiology #Electrophysiology #AVRT #WPW #ECG | Abdallah Othman

Medical explainer on Instagram: "The immediate action of intravenously injected adenosine is extremely rapid and short-lived, primarily targeting the Atrioventricular (AV) node in the heart. ⚡ Immediate Action: AV Nodal Blockade/Slowing: Adenosine binds to A_1 receptors in the AV node, which leads to: Slowing of conduction time through the AV node. Interruption of re-entry pathways that rely on the AV node. This effect can momentarily cause a short-lasting heart block (first, second, or third de

The EP Journey on Instagram: "Roughly 1 in 1000 people are born with an extra electrical connection between the atria and ventricles — called an Accessory Pathway or Bypass Tract. This extra pathway creates a shortcut that allows impulses to bypass the AV node, forming a re-entrant circuit between the AV node and the accessory pathway — sustaining an SVT (AVRT). 👉 The good news? Catheter ablation can target and eliminate the pathway — effectively curing the SVT. 📈 ECG Signs of an Accessory Pat
