Combined Epicardial-Endocardial Approach to Ablation of Inappropriate Sinus Tachycardia.

摘要

Epicardial-Endocardial Approach to IST Ablation. A combined epicardial-endocardial approach to ablation of inappropriate sinus tachycardia in a highly symptomatic patient who failed to respond to medical therapy and endocardial ablation is described. The anatomy and physiology of the sinus node is discussed, providing a basis for performing this procedure. This case provides an additional therapeutic option for a condition that often is difficult to manage. (J Cardiovasc Electrophysiol, Vol. 15, pp. 237-240, February 2004)
