ABSTRACT:
A sensor for use with a rate-responsive pacemaker is disclosed which is responsive to blood oxygen content, thereby allowing the cardiac rate of the pacemaker to closely mimic the natural response pattern of the heart to changing physiological need. The sensor integrates the output from a photosensor driven by blood-reflected light from an LED, and when the integrated output reached a predetermined threshold latches the circuit, enabling the use of time to indicate the level of blood oxygen content. The sensor thus advantageously requires neither a voltage doubler in the driving circuitry, or an analog-to-digital converter in the output circuitry, reducing both complexity and power consumption of the blood oxygen sensor.
