Abstract
A pacemaker with position sensing capability permits built-in monitoring of hemodynamic changes. A miniature position sensor, such as a magnetic coil, is fixed to each implanted pacing lead. The pacemaker housing contains a generator unit, including a magnetic field transmitter. The magnetic field transmitted by the generator unit causes the position sensors to generate position signals, which are returned via the pacing leads to a control unit of the pacemaker. Based on these signals, the control unit senses relative positions of the location sensors, and hence the motion of the leads in the heart. Other location sensing techniques are also disclosed.
