Minute volume rate-responsive pacemaker using dual unipolar leads |
摘要 |
A rate-responsive pacemaker including a pulse generator for providing pacing current pulses at a controlled rate and two unipolar leads are provided. The pulse generator also applies a measuring current between one of the electrodes and a reference point in the pacemaker. The impedance between the other electrode and the reference point is measured across a lung of the patient. The impedance of the patient varies as a function of patient's pleural pressure, and therefore, the impedance thus represents the patient's minute volume. The rate of pacing is automatically adjusted in response to changes in the patient's minute volume.
