Lesson Thirty-two New Algorithm Using Only Lead aVR for Differential Diagnosis of Wide QRS Complex Tachycardia
Making an accurate rapid diagnosis in patients with wide QRS complex tachycardia remains a signifi-cant clinical problem1. We recently proposed a new simplified four-step decision treelike algorithm to dis-tinguish between regular monomorphic wide QRS com-plex tachycardias caused by supraventricular ventricular tachycardia (SVT) and ventricular tachycardia (VT).
