Energy controlled rate-responsive pacemaker having automatically adjustable control parameters |
摘要 |
A device for use as a rate-responsive pacemaker is disclosed in which the pacing interval is controlled by the amount of energy contained in a raw signal generated by a suitable physiological sensor and processed by an energy converter to generate an output energy signal coupled to the pacemaker control circuits to adjust the pacing interval. The energy converter may be a rectifying amplifier and an integrating circuit, a voltage controlled oscillator whose frequency is measured over a suitable time interval using a time interval generator and a counter with the output of the counter being used by the control circuits of the pacemaker to vary its pacing interval, or means for measuring energy content of the raw signal and storing that measurement in memory and periodically processing it to alter the transfer characteristics of the rate-responsive pacemaker.
