Patent ID: 11420068

Abstract:
A method and a medical device for implementing a dual-chamber pacing mode without ventricular pacing are disclosed. The method includes: obtaining pacing mode information configured by a user; controlling a dual-chamber pacemaker to operate in an ADD mode and detecting whether there is a need for delivering a pace; and performing a predetermined interruption process if a need for delivering a pace is detected. The predetermined interruption process includes: 2041) determining whether a chamber to be subsequently paced is a ventricle; 2042) if it is determined that the chamber to be subsequently paced is a ventricle, determining whether there is a need for delivering a real ventricular pace; 2043) if delivery of a real ventricular pace is not needed, delivering a virtual ventricular pace VVP and resetting a first atrial escape interval; and returning after the predetermined interruption process is terminated. According to the present method and device, physiological transitioning to or from a DDD mode is enabled when so desired, resulting in reduced patient discomfort. In addition, enhanced implementation convenience, reliability and direct validatability with reduced verification workload can be achieved.
