Title:
PHYSIOLOGICAL MODE SWITCHING CONTROL METHOD FOR CARDIAC THERAPY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/001479
Kind Code:
A1
Abstract:
Disclosed is a physiological mode switching control method for a cardiac therapy device. The method comprises the following steps: S1: using a unified functional module to realize mode switching, and configuring different operating modes of the cardiac therapy device in a bit combination manner; S2: starting a mode switching process after a mode switching request has been received, detecting that a valid cardiac event exists in the switching process, and determining, according to the type of the valid cardiac event and the types of the operating mode before and after conversion, the opportunities for mode switching and timing setting; and S3: determining, according to the type of the valid cardiac event and the type of the converted operating mode, a timing interval that is set in the process of mode switching, and controlling the mode switching process to be completed within a cardiac cycle. The present invention can simultaneously take into account the AV conductivity, the heart rate stability and the timing stability, has the characteristics of fast response speed, flexible operation and simple action, and solves the problems in the existing mode switching of low response speed, long interval possibly occurring in mode switching, asynchronous A and V timings, and unstable heart rate.
