Abstract
An atrium controlled heart pacemaker has a switching stage which is controlled in dependence upon the appearance of atrial signals. The switching stage switches the heart pacemaker to a VVI mode for a predetermined number of stimulation pulses or natural ventricular events, or a predetermined time, upon the appearance of at least one atrial signal before a selected time limit. The time limit is derived from the difference between a smallest synchronous interval and the AV delay.
