[Improving interference freedom of asynchronous cardiostimulators].

Abstract

In their every day life the patients with implanted cardiostimulators are infrequently undergo the effects of electromagnetic interference sources that might seriously disrupt the normal performance of cardiostimulators (CS). For the asynchronous CS (EKC-2, EKC-4, EKC-8) the dependence of the CS pulse repetition period on the the frequency and amplitude of interferences is given. The interference resistance and stability of these apparatus is shown to be materially increased if a condenser of 10 nF capacity is to the CS output terminals connected.
