Study Summary

The Sensor Optimization of Cardiac Resynchronization Therapy (CRT) Response (SOCR) Study is a multicenter, prospective, non-randomized acute feasibility study that is being conducted to determine if subcutaneous heart sounds and/or intracardiac impedance can acutely identify the optimal atrioventricular (AV) pacing intervals and optimal left ventricular (LV) electrodes in patients indicated for cardiac resynchronization therapy.

Primary Outcome

Current practices use the measurement LV dP/dt max to determine how the AV interval should be programmed in a CRT device. Intracardiac impedance is another method that could be used to determine the optimal AV interval. This outcome measure is the number of patients where the optimal AV interval setting as determined by intracardiac impedance agrees within one AV interval setting (30 milliseconds) of the optimal setting determined by LV dP/dt max.
