Abstract
An atrium-controlled heart pacemaker has a monitoring circuit for interrupting tachycardia which may be generated by the pacemaker. The monitoring circuit includes a P-wave counter and a window generator connected thereto. The window generator prescribes a window for the P-wave counter within which a predetermined maximum number n of P-waves is allowed to appear. When the n.sup.th P-wave appears in the window, forwarding of the n+1.sup.th P-wave to the stimulation circuit is blocked.
