Abstract

1396366 Heart pacemakers AMERICAN OPTICAL CORP 19 July 1972 [19 July 1971] 12448/74 Divided out of 1396365 Heading A5R The disclosure is identical to that in Specification 1396365 but the claims relate to a heartbeat stimulating apparatus monitoring system for monitoring a power supply of the aparatus which is aranged to produce electrical heartbeat stimulating pulses, the system comprises a. device having means for sensing a decrease in the voltage of the power supply the device also having pulse width control means responsive to the operation of said sensing means for increasing the width of each stimulating pulse produced by the heartbeat stimulating apparatus or a function of said voltage decrease, the system also comprising means for monitoring said pulse width control means for providing an indication of the voltage remaining in the power supply.
