Freedom From Left Ventricular Lead-Related Complications Through 3 Months3 months

The primary safety endpoint for this study is freedom from left ventricular lead-related complications through 3 months.

Freedom From System-related Complications Through 3 Months3 Months

The co-primary safety endpoint for this study is freedom from system-related complications through 3 months.

The Primary Effectiveness Endpoint for the Promote Q System Was the Responder Rate to Biventricular Pacing at 3 Months.3 Months

The primary effectiveness endpoint for the Promote Q system was the responder rate to biventricular pacing at 3 months. A responder per protocol was defined as a patient with an LV pacing threshold of \<2.5 V at 0.5ms in the D1-M2 pacing configuration (Vector 1) AND at least one other non-standard programmable biventricular lead vector. Non-standard vectors included Vector 2 (D1-P4), Vector 4 (M2-P4), Vector 6 (M3-M2), Vector 7 (M3-P4), Vector 8 (M3-RV coil), Vector 9 (P4-M2) and Vector 10 (P4-RV coil).
