In the field of cardiac resynchronization therapy is left ventricular pacing via the coronary sinus a mature technique.

Abstract

In the first reported case of cardiac resynchronization therapy (CRT) in 1994, left ventricular (LV) pacing was performed using an epicardial approach. ¹ The use of a lead inserted into a coronary sinus (CS) tributary vein to pace the LV was initially proposed in patients in whom right ventricular (RV) pacing could not be performed by a transvenous approach and later by Blackburn and Gibbs ² and Daubert et al.³ for cardiac resynchronization.
