NCT02699944

Brief Summary

Despite advancements in implant technology and various techniques of optimization, there is still around 30% non-responder rate to cardiac resynchronization therapy (CRT). This study will assess the potential benefit of a body surface mapping technology to optimize CRT devices in the chronic sub-optimal responder setting.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Change in left ventricular end-systolic volume

    6 months after optimization

Secondary Outcomes (1)

  • Determine the degree to which echocardiographic measures of LV function correlate with ECG Vest measures

    6 months after optimization

Study Arms (1)

CRT sub-optimal responder

EXPERIMENTAL

Subjects who have had CRT for at least 6 months and who have not responded as well as they could, in their cardiologists opinion. Subjects' ejection fraction are still \<50% despite CRT. A ECG Vest Optimization protocol will be utilized as one aspect to determine the best CRT programming for each individual subject.

Device: ECG Vest Optimization

Interventions

As part of a standard and clinically indicated CRT optimization procedure utilize an ECG Vest as one modality for collecting information to determine best device programming.
