Narrow Complex Ventricular Tachycardia
Myocardial infarctions are frequently complicated by tachyarrhythmias, which commonly have wide QRS complexes (QRS duration > 120 milliseconds). Many published criteria exist to help differentiate between ventricular and supraventricular mechanisms. We present a case of a 61-year-old male with a history of hypertension, hyperlipidemia and coronary artery disease with prior stenting of the right...
متن کاملIschemic Ventricular Tachycardia Presenting as a Narrow Complex Tachycardia
This report describes a patient presenting with a narrow complex tachycardia in the context of prior myocardial infarction and impaired ventricular function. Electrophysiological studies confirmed ventricular tachycardia and activation and entrainment mapping demonstrated a critical isthmus within an area of scar involving the His-Purkinje system accounting for the narrow QRS morphology. This v...
متن کاملVentricular Tachycardia with Narrow QRS
gram. Tachyeardias originating in the left bundle branch and documented by right, left, and His bundle recordings have been produced in animals given excessive digitalis. We have noted a similar tachycardia in a patient with ischemic heart disease receiving digitalis during hypokalemia. The QRS complexes were 0.10 sec in duration and by contour suggested an ectopic focus located in the posterio...
متن کاملA Narrow QRS Complex Tachycardia:
An 80-year-old man underwent an electrophysiologic procedure because of recurrent episodes of supraventricular tachycardia. Episodes of nonsustained narrow QRS complex tachycardia occurred spontaneously after catheter placement. Examples of the onset and termination of an episode of tachycardia are shown in Figures 1 and 2, respectively. What is the mechanism of the tachycardia? What is the lev...
