Brief summary

Enrolled patients implanted with Biotronik CRT-D and QP lead equipped with MultiPole pacing mode is grouped into which programmed into MultiPole pacing, or conventional bi-ventricular pacing mode. They are followed up by seven month post implantation, and predefined cardiac functional parameters are collected at each visit.

Detailed description

Enrolled patients will undergo the baseline medical tests to assess the cardiac functions (e.g. echo, blood test, and 12-Lead ECG) prior to the implantation of Biotronik CRT-D and QP lead featured with MultiPole Pacing parameter. At implantation, LV-LV conduction delays are measured in predefined LV pacing and sensing configurations. One month after the successful implantation, the patients revisit the investigation site to be adjudicated for programming MultiPole pacing or continuing bi-ventricular pacing mode, based on their echo readings by then. Patients are subsequently followed up at four and seven month post implantation to acquire the LV-LV conduction delays and echo readings, etc. at the time.

Design outcomes

Primary

Measure	Time frame	Description
Correlation between LV-LV/RV-LV intra-cardiac conduction time and multiple hemodynamic parameters	through study completion, an average of 7 months	LV-LV/RV-LV intra-cardiac conduction time will be obtained at each time frame, and correlation will be investigated with variation of multiple hemodynamic parameters from baseline up to seven month follow up.

Secondary

Measure	Time frame	Description
Rate of arrhythmia episodes	through study completion, an average of 7 months	Comparison between patient groups in terms of rate of arrhythmia
Influence by baseline characteristics	through study completion, an average of 7 months	An alanysis of the impact of the baseline characteristics on other outcomes
