Implantable cardiac pacer and process for operating a cardiac pacer with a synchrous rate of stimulation of the cardiac muscle limited to a maximal value

摘要

The invention relates to an implantable cardiac pacemaker with means for detecting spontaneous cardiac muscle contractions in the area of an atrium and means for stimulating cardiac muscle contractions in the area of a ventricle, which, after detection of a spontaneous cardiac muscle contraction in the area of the atrium, stimulate a cardiac muscle contraction in the area of the ventricle. In this case it is proposed that the rate of stimulation of cardiac muscle contractions in the area of the ventricle should be limited to a maximum value (HSR) which slightly exceeds the heart rate (AR) adapted to the respective physical activity (KA) of the patient. …IMAGE…
