NCT01609985

Brief Summary

The Cutaneous Heart Sounds Data Collection During CRT Optimization study is an acute, prospective, non-randomized multi-center feasibility clinical trial. The purpose of this clinical trial is to collect data to assist in the testing and finalization of a hemodynamic sensor-based cardiac resynchronization therapy (CRT) optimization scheme.

Outcome Measures

Primary Outcomes (1)

  • Collection of simultaneous cardiac signals representing heart sounds and CRT-D electrogram (EGM) vectors.

    The cardiac signals collected by the modified Virtuoso® ICD and implanted CRT-D EGM vectors will be used to determine how to improve and finalize a prototyped hemodynamic sensor-based CRT optimization scheme.

    A two hour office visit within two years of CRT-Defibrillator (D) and lead system implant

Secondary Outcomes (2)

  • Comparison of modified Virtuoso® Implantable Cardiac Defibrillator (ICD) heart sounds and CRT-D electrogram (EGM) vectors

    A two hour office visit within two years of CRT-D and lead system implant

  • Determine if modified Virtuoso® ICD recorded heart sounds and CRT-D recorded EGM are able to detect phrenic nerve stimulation (PNS)

    A two hour office visit within two years of CRT-D and lead system implant
