ABSTRACT:
A pacemaker system includes an electrode lead having a distal tip electrode for supplying stimulation pulses to cardiac tissue and a ring electrode, the electrode lead being connected to a cardiac stimulator. A detector is contained in a stimulator housing and is connected to the electrode lead for detecting electrical cardiac activity between said ring electrode and said tip electrode. Measurement of a signal dependent on physical activity of the subject in whom the pacemaker is implanted is obtained either by applying a voltage on the ring electrode during a predetermined measuring period and measuring a current through the ring electrode during at least a part of this period, or by, after detection of a QRS wave, applying a potential on the ring electrode and measuring the current between the housing and the ring electrode during the measuring period and also applying an alternating current between the tip electrode and the housing and measuring a voltage difference between the tip electrode and the ring electrode. The stimulation rate is then adjusted dependent on the measured value or values obtained.
