Tachycardia [Disease/Finding] Tachycardia, Ventricular [Disease/Finding] D017180 N0000003541 Tachycardia, Ventricular Tachycardia, Ventricular C0042514 1023929 M0026083 25569003 Ventricular Tachycardia C7260 An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).
