ABSTRACT

The diagnosis of myocardial ischemia is not confine to the alteration of the RS-T segment and of the T wave. Conduction disorders at any level can be caused by the ischemia itself and contribute to the diagnosis, as well as the ventricular arrhythmias. On the other hand, conduction blocks do not hinder or hide the diagnosis of ischemia. The primary and secondary characteristics of the T wave and RS-T segment are discussed. The relevance of the knowledge of ventricular activation vectors in bundle branch blocks is shown, as well as their alteration in case of associated myocardial infarction. Emphasis is made on the importance of the deductive method in the electrocardiographic interpretation.
