ABSTRACT:
An implantable cardioverter including two electrodes for sensing depolarizations of a chamber of a patient's heart, one electrode providing a near field signal, one electrode providing a far field signal. The device defines a desired cardioversion pulse delivery time as a first time interval following the onset of the far field signal. The device measures a second time interval between the onset of the far field signal and the detection of the near field signal, and delivers the cardioversion pulse synchronized to the detection of the near field signal, using the first and second time intervals to define a synchronization interval following detection of the near field electrogram.
