Abstract
In order to improve the accuracy of the pacemaker's parameter adjustment and to avoid the surgical replacement of the pacemaker when the battery is exhausted, this paper designs a novel single-chamber pacemaker circuit based on low-power single-chip microcomputer. The circuit uses digital control to accurately control the amplitude, pulse width and frequency of the pacing pulse. The circuit is also designed with wireless charging function, and wireless communication with the programmer can wirelessly charge the pacemaker and know the charging information in real time. Wireless charging function can reduce the number of times the patient replaces the pacemaker or even completely avoid it.
