ABSTRACT:
A device for detecting pathological tachycardia, in particular for use with an implantable device for terminating tachycardias, having a classifican device, responding to at least one electrical signal derived from the heart, which if the classification criterion is met outputs an output signal indicating pathological tachycardia, having a plurality of classification devices for checking various classification criteria within one heart interval or on the basis of the evaluation of preceding heart intervals; a controllable counter that is connected to the outputs of the classification devices via first logic means; means for incrementing the counter state of the counter by a predetermined counting amount each time, if during a heart interval at least one of the primary classification signals appears; means for keeping the counter state constant or decrementing it by a predetermined counting amount, if no primary classification signal appears within the heart interval; and discriminator means, which output the output signal indicating the occurrence of pathological tachycardia if the counter state of the counter exceeds a predetermined value.
