Outcome Measures
Primary Outcomes (1)
To compare the aortic velocity time integral value derived by the QuickOptTM optimization method with that derived by the standard echocardiography optimization methods
1 day
Secondary Outcomes (2)
Time required for each optimization method considered in this study
1 day
Effects of any spontaneous cardiac events during the QuickOpt optimization process and these events are not limited to premature ventricular complex (PVC), pacemaker-mediated tachycardia (PMT), atrial fibrillation (AF) and far-field R-wave oversensing
1 day
Study Arms (1)
QuickOpt
EXPERIMENTALQuickOpt is an optimization algorithm to program the AV, PV and VV delays
Interventions
The QuickOpt algorithm will suggest values for programming AV, PV and VV delay.
