Ventricular Escape Rhythm (Idioventricular Rhythm) A ventricular escape rhythm is a life-preserving, default cardiac rhythm that emerges when there is failure of higher pacemakers. It occurs when the rate of supraventricular impulses arriving at the ventricles falls below the intrinsic firing rate of the ventricular pacemaker cells. Pacemaker Hierarchy & Intrinsic Rates: · SA Node: 60–100 bpm · AV Node (Junctional): 40–60 bpm · Ventricles: 20–40 bpm Mechanism: When impulses from the SA and AV no

Ventricular Escape Rhythm occurs when the ventricles take over pacing due to failure of the SA and AV nodes. SA Node: 60–100 bpm AV Node: 40–60 bpm Ventricles: 20–40 bpm 🚨 Causes Severe sinus disease Advanced AV block Myocardial infarction Drug toxicity (e.g., beta-blockers, digoxin) Hyperkalemia Cardiac surgery complications. #Cardiology #ECG #Arrhythmia #MedEd #idioventricularrhythm | Abdallah Othman

Ventricular tachycardia is an abnormal heart rhythm coming from the bottom chamber of the heart. Dr. Weijia Wang, electrophysiologist at Marshfield Medical Center, explains what ventricular tachycardia is and how to treat it whether it be with catheter ablation or stereotactic body radiation therapy. | Marshfield Clinic Health System
