Pulse stimulation device and method, and medical apparatus

A pulse stimulation device, comprising an R-wave sensing module, a cardiac stimulation pulse generator, and at least one control electrode, wherein the control electrode corresponds to a preset stimulation position;

• the control electrode is electrically connected to the R-wave sensing module and the cardiac stimulation pulse generator, respectively, and the R-wave sensing module is communicatively connected to the cardiac stimulation pulse generator;
• the R-wave sensing module is used to obtain a surface electrocardiogram and/or obtain a myocardial electrocardiogram by collecting an electrocardiogram signal based on the control electrode;
• obtain a first R-wave sensing time of an R-wave occurrence based on the myocardial electrocardiogram and/or a second R-wave sensing time of an R-wave occurrence based on the surface electrocardiogram;
• and
• determine a first pulse delivery time corresponding to the preset stimulation position according to the first R-wave sensing time and/or a second pulse delivery time corresponding to the preset stimulation position according to the second R-wave sensing time;
• the cardiac stimulation pulse generator is used to deliver a cardiac electrical stimulation pulse for CCM to the corresponding control electrode according to the first pulse delivery time and/or the second pulse delivery time.
