Abstract

In an implantable cardiac device, atrial signals, spaced either spatially or temporally, are sensed and stored. The morphology of the signals are compared and an atrial fibrillation indication is generated if the signals are different. The device then either changes its mode of operation or applies appropriate therapy.
