ABSTRACT:
An implantable heart stimulator has a heart signal detector adapted to detect electrical heart signals and to apply the detected signals to at least two detection channels. Each detection channel includes a filter, with each filter having a passband that differs from the passband of the other filters. Each channel also includes a threshold detector and a peak amplitude determining unit connected to the output of the filter in that channel. A heart event identifying unit is connected to the outputs of each channel and unambiguously identifies a type of signal which produced a detected heart event by applying predetermined identifying criteria to the outputs of the threshold detector and the peak amplitude determining unit from each channel.
