Problems solved by technology

However, giving up the right atrial electrode means that the right atrium (RA) information cannot be obtained for CRT treatment technology, and more importantly, the AS-VS / VP interval cannot be obtained through hardware and software, so that it is impossible to perform CRT treatment. The necessary AS-VP automatic search scanning program cannot find the narrowest VP through the scanning search process necessary for CRT treatment, and of course it is impossible to find the AS-VP interval corresponding to the narrowest VP (QRS) necessary for CRT treatment.

Embodiment Construction

[0076] 1. CRT-GY2 pulse generator system infrastructure and design goals

[0077] From the existing CRT pacing technology, it is not difficult to see that the atrium (A) and ventricle (V) signals are indispensable physiological parameters for CRT technology, and the AS-VS interval constructed by both A wave and V wave It is the basis for CRT pacing technology to perform therapeutic operations. However, the existing CRT technology system is in the state of establishing communication with the CRT pulse generator, coupled with the connected body surface ECG electrodes, and the supporting program-controlled instrument, under manual operation, performs scanning AS / AP- The VS / VP interval search program searches for the AS / AP-VS / VP interval corresponding to the narrowest V wave, and performs CRT pacing therapy at this interval.

[0078] The design idea of ​​the present invention is: firstly, only for LBBB patients whose atrioventricular (AV) node can transmit normally at a ratio of ...

Abstract

The invention discloses a heart pacemaker and heart pace-making system for realizing CRT treatment based on a single electrode. The heart pace-making system comprises a heart pacemaker and a program-controlled instrument used for controlling the heart pacemaker, wherein the heart pacemaker includes a pulse generator and a pace-making catheter, the pulse generator includes a housing and a pulse generating system located in the housing, and the housing includes a metal upper shell, a metal lower shell and an insulating isolation layer located between the metal upper shell and the metal lower shell. The heart pace-making system discards the separated processing situation of the traditional CRT which separately receives right atrium, right ventricle and left ventricle signals through multipleelectrodes, realizes that the housing of the pulse generator and a left ventricle epicardial electrode construct double-electrode symmetrical AV signal single-channel acquisition, achieves the integrated processing of A waves, V waves and AV so as to provide all ECG parameters necessary for the CRT technology. The heart pace-making system is simpler and more convenient in clinical operation, lowerin production cost and price and higher in intelligent level.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a cardiac pacemaker and a cardiac pacemaker system for realizing CRT treatment based on a single electrode. Background technique [0002] At present, in the clinical application of conventional CRT technology, three electrode catheters are mostly implanted, which are respectively implanted in the apex of the right ventricle, the right atrial appendage, and the left ventricle. Among them, the left ventricular electrode catheter passes through the coronary sinus and enters the vein close to the left ventricular side wall to achieve epicardial pacing. Specifically, a total of three electrodes are placed in the vein of the left ventricle, the apex of the right ventricle, and the right atrium to achieve right atrium (RA) and left and right biventricular pacing modes. By setting the individualized atrioventricular interval (A-V interval), indoor conduction interval (LV-RV...
