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

Intraventricular conduction delay (IVCD) is a critical ECG finding, marked by a widened QRS complex (≥120 ms), reflecting delayed electrical conduction within the ventricles. Left bundle branch block (LBBB) is characterized by a deep S wave in lead V1, broad, single-peaked R waves in lateral leads (I, aVL, V5-V6), and a delayed R wave peak time (>60 ms in V5-V6), indicating left ventricular conduction impairment. Conversely, right bundle branch block (RBBB) presents with a QRS duration exceeding
