Electrophysiologic studies in patients with ventricular tachycardia.
Invasive electrophysiologic studies are used to guide drug and non-pharmacologic therapy, including surgery, in patients with ventricular tachycardia. We discuss the indications, methods, and results of electrophysiologic studies in these patients. Both catheter and intraoperative studies are described. This approach to patients with ventricular tachycardia is contrasted to the approach using noninvasive electrocardiographic monitoring.
