May aid differential diagnosis of wide QRS tachycardias; leaves open prospective validation of mechanism-based algorithms.
Wide QRS Complexes. Wide QRS complex tachycardia is a commonly encountered arrhythmia and its appropriate diagnosis often poses a challenge to most physicians. The origin of a wide QRS complex is either supraventricular with abnormal ventricular activation or ventricular. This review addresses the main electrophysiologic mechanisms involved in the genesis of a wide QRS complex and its maintenance as a sustained arrhythmia.
