Exercise Capacity Improvement by Conduction System Pacing in heArt Failure patieNts Without Compelling CRT inDication

In the conduction system pacing group, the right ventricular lead will be placed in a septal position to achieve conduction system pacing, either His bundle pacing (HBP) or left bundle branch area (LBBA) pacing. In the usual care group, the right ventricular lead will be placed in the right ventricle apex as usual.

This is the usual care group. Patients will receive a pacemaker device with the right ventricular lead inserted in the apex and not in the septal position.
