Tachycardia, Diagnosis, Criteria


Wide QRS tachycardias represent one of the most challenging scenarios in the interpretation of the electrocardiogram, even among experienced professionals or specialists. The various existing diagnostic criteria are essential tools for the correct identification of the origin of tachycardia, however, the knowledge of the electrophysiological principles of cardiac depolarization is fundamental to understand them, thus allowing greater accuracy in the interpretation of the exam.
