Patent ID: 6923772

Claim:
A device for measuring a synchronicity of contraction of a heart to determine if an individual would be a responder to cardiac resynchronization therapy, the device comprising: a first electrode adapted to be positioned at a first ventricular wall location and configured to mechanically measure movement of the first ventricular wall location; a second electrode adapted to be positioned at a second ventricular wall location and configured to mechanically measure movement of the second ventricular wall location; a processing module coupled to the first and second electrodes, the processing module adapted to process a first signal produced by the first electrode at the first ventricular wall location and a second signal produced by the second electrode at the second ventricular wall location and generate an output based on the processed signals; and a comparator module coupled to the processing module to indicate that the individual would be a responder if the output of the processing module exceeds a threshold and to indicate that the individual would be a non-responder if the output of the processing module is below the threshold.
