Title:
PACEMAKING SWITCHING CIRCUIT, PACEMAKING SWITCHING APPARATUS, AND IMPLANTABLE CARDIAC PACEMAKER
Document Type and Number:
WIPO Patent Application WO/2021/232788
Kind Code:
A1
Abstract:
The present application belongs to the technical field of medical instruments, and provides a pacemaking switching circuit, a pacemaking switching apparatus, and an implantable cardiac pacemaker. A first electrode and a second electrode are connected by means of an electrocardiogram acquisition circuit so as to receive electrocardiogram acquisition signals, and a switching circuit is used to connect a pacemaking circuit to the first electrode and the second electrode. The switching state of the switching circuit is controlled by means of a switching control signal, thus controlling the output state of a pacemaking pulse signal, and then the pacemaking circuit and the electrocardiogram acquisition circuit are integrated into the same circuit. Instant switching is performed according to requirements, and the problem is solved in which the circuits of existing pacemakers have large volumes, extremely complicated structures, and high power consumption.
