Key result
Electrophysiologic study provides diagnostic and prognostic value for managing VT, unexplained syncope, and guiding therapy.
Why the study?
Electrophysiologic study is important for managing patients with ventricular tachyarrhythmias but its specific indications require clarification.
What are the indications for electrophysiologic study in patients with ventricular arrhythmias?
What are the indications for electrophysiologic study in patients with ventricular arrhythmias?
Electrophysiologic study is a critical tool for the diagnosis, risk stratification, and management of patients with ventricular arrhythmias and unexplained syncope.
Electrophysiologic study provides valuable information in the management of patients with known or suspected ventricular tachyarrhythmias. It should be used when there is uncertainty about the origin of a wide QRS tachycardia. It is useful in evaluating heart disease patients with unexplained syncope and in stratifying prognosis and guiding therapy in patients with malignant ventricular arrhythmias. All patients being considered for treatment of ventricular tachyarrhythmias with an electrical device should undergo thorough electrophysiologic study. Electrophysiologic study is also indispensable in guiding ablative therapy in patients with drug-refractory malignant ventricular arrhythmias.

Pinski et al. (1992) conducted a review in Ventricular arrhythmias. Electrophysiologic study was evaluated. Electrophysiologic study provides valuable diagnostic and prognostic information for managing ventricular tachyarrhythmias, evaluating unexplained syncope, and guiding device or ablative therapy.
