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 wave in sinus rhythm (WPW). - WP

Reentrant Tachycardia vs. Junctional Tachycardia 🚀 Reentrant tachycardia refers to abnormal rapid heart rhythms caused by re-entry circuits within the heart. Let’s explore the differences between atrioventricular re-entry tachycardia (AVRT) and junctional tachycardia (JT): Atrioventricular Re-entry Tachycardia (AVRT): Mechanism: Occurs in patients with accessory pathways (often seen in Wolff-Parkinson-White syndrome). ⚡ECG Features: Orthodromic AVRT: Anterograde conduction via the AV node, resu
