Embodiment Construction

[0034] The implantation detection circuit, implantation detection method and device of the cardiac pacing system of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0035] The physiological basis of the cardiac pacing system is that the myocardium can produce a contraction response to any form of electrical stimulation. Using this, the pacemaker of the cardiac pacing system can give direct electrical stimulation to the diseased heart as needed, artificially making the heart Get back to normal. Cardiac pacing systems can be divided into two types: external temporary pacing...

Abstract

The invention relates to an implantation detection circuit, an implantation detection device and an implantation detection method for a cardiac pacing system. The implantation detection circuit comprises a detection module and a voltage comparison module which are connected with a pacing circuit, the detection module is used for successively detecting the voltage of a pacing pulse before and afterelectric discharge and outputting the voltage difference signal of the pacing pulse before and after the electric discharge, the voltage comparison module is used for judging whether a voltage difference exceeds preset threshold voltage, and the voltage comparison module is further connected with the control module of the cardiac pacing system so as to transmit a comparative result to the controlmodule. Compared with traditional implantation detection technology, the implantation detection circuit of a cardiac pacemaker system of the invention does not need to accurately measure current value, electrode impedance or voltage difference value, and is conducive to lowering design difficulty and simplifying a circuit structure. Further, the detection module can be realized by detection capacitors, which have a certain connected relation, and four switches, and is high in detection accuracy, simple in structure and relatively low in power consumption.

Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to an implantation detection circuit of a cardiac pacing system, an implantation detection device and a method, and also relates to a readable storage medium and a cardiac pacing system. Background technique [0002] Since the invention of the cardiac pacing system in the 1950s, both its therapeutic indications and functions have been greatly developed. In addition to the pacing function, the cardiac pacing system is also used for various arrhythmia-related diagnostic techniques. [0003] The known cardiac pacing system includes a pacemaker (cardiac pacemaker) and electrode leads, and the pacemaker and the electrode leads are implanted in the human body during the implantation operation. The pacemaker is powered by a battery and can pass through a pulse generator when needed. Distribute tiny electrical pulses (ie, pacing pulses) powered by batteries to the heart. Through the cond...
