Nonsustained ventricular tachycardia

Abstract

The value of electrophysiological testing in guiding antiarrhythmic therapy was examined in a study of 62 patients with nonsustained ventricular tachycardia and chronic coronary artery disease. This study demonstrated that patients with electrophysiologically inducible sustained ventricular tachycardia and ejection fractions less than 40% are at high risk for sudden cardiac death. Patients at high risk who are discharged on an antiarrhythmic regimen that prevents induction of sustained ventricular tachycardia by programmed stimulation appear to be at lower risk for sudden death.
