Embodiment Construction

[0044] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the application and together with the description serve to explain the principles of the application.

[0045] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings that need to be used in the description of the embodiments or the prior art. Obviously, for those of ordinary skill in the art, In other words, other drawings can also be obtained from these drawings without paying creative labor.

[0046] The first thing to explain is that RA means the right atrium;

[0047] RV means the right ventricle;

[0048] LV means the left ventricle;

[0049] AP represents atrial pacing marker;

[0050] RVS indicates right ventricular sensing marker;

[0051] RVP represents right ventricular pacing marker;

[0052] LVP stands...

Abstract

The invention provides a device for automatically measuring a left ventricular pace-making threshold and a control method thereof. The device comprises a right atrial electrocardio data acquisition module, a right ventricular electrocardio data acquisition module, a heart rhythm stability detection module, an interventricular conduction stability detection module, a left ventricular pacing capturedetection module and a left ventricular pacing pulse generation module. The control method comprises the following steps: 1, detecting heart rhythm stability, wherein if the atrial rate fluctuates around an average value, and the conduction from the right atrium to the right ventricle fluctuates around the average value, executing the step 2; 2, detecting interventricular conduction stability, wherein if the conduction from the left ventricle to the right ventricle fluctuates around an average value, executing the step 3; 3, setting a certain range near the conduction average value from the right atrium to the right ventricle as a capture loss window, setting a certain range near the conduction average value from the left ventricle to the right ventricle as a capture loss window, and if the two windows do not overlap, executing the step 4; 4, gradually decreasing the left ventricular pacing pulse amplitude, and determining the threshold by the capture and capture loss windows.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for automatically measuring the left ventricular pacing threshold and a control method thereof. Background technique [0002] In recent decades, with the aging of the social population, the number of people with heart failure has shown a trend of increasing year by year. With the rapid development of drug therapy, cardiac resynchronization therapy (CRT) developed in the 1990s also opened up a new treatment platform for heart failure patients, which improved the heart function of many drug-refractory congestive heart failure patients, and significantly Reduced the fatality rate. [0003] The exact curative effect of CRT has been confirmed by multiple large-scale clinical trials, and 100% biventricular synchronized pacing is the prerequisite for its effective work. However, in actual situations, the left ventricular electrode is prone to dislocation or micro-disl...
