Echocardiographic Assessment During Exercise of Heart Failure Patients With Cardiac Resynchronization Therapy

This prospective echocardiographic study investigated the respective impacts of left ventricular (LV) pacing and simultaneous and sequential biventricular pacing (BVP) on ventricular dyssynchrony during exercise in 23 patients with compensated heart failure and ventricular conduction delays. During...
