Optional technology of invasive temporary cardiac on-demand pace-making sensing source

Abstract

The invention discloses an optional technology of an invasive temporary cardiac on-demand pace-making sensing source. According to the optional technology of the invasive temporary cardiac on-demand pace-making sensing source, a self-developed temporary cardiac on-demand pacemaker is connected and combined with a monitor in a matched manner; a combined pace-making and monitoring integrated instrument provides a more reliable pacing-sensing technology; the pacemaker collects intracardiac electrocardiogram signals through a pace-making electrode; the intracardiac electrocardiogram signals are transmitted to the monitor through using a communication module; intubation medical staff observe an intracardiac electrocardiogram through the monitor, and accurately judges a location where the electrode is located based on a synchronous surface electrocardiogram; after the pace-making electrode is led to a proper position, the pacemaker carries out on-demand pace-making on ventricles; as for the problem of difficulty in fixing a pace-making position in the clinical temporary cardiac pace-making VVI technology, the integrated pace-making and monitoring integrated technology can greatly improve the understanding of the medical staff on pace-making states greatly; and as for the problem of difficult processing caused by a situation that a clinical temporary cardiac on-demand pace-making sensing source is unreliable, surface electrocardiogram R waves from the monitor are provided and are adopted as a stable ventricular pace-making source.

Description

technical field [0001] The invention relates to the field of medical electronic instruments, and more specifically relates to an optional technology for an invasive temporary cardiac on-demand pacing sensing source. Background technique [0002] Invasive temporary cardiac on-demand pacing technology is one of the most important clinical treatments at present. The traditional invasive temporary cardiac on-demand pacemaker is placed in the patient's heart cavity through a pacing catheter connected to the pacemaker, and the pacing electrode (bipolar) collects intracardiac electrical signals while emitting pacing pulses. And input the electrical signal in the heart chamber to the ECG preamplifier, and then pass through a series of signal processing circuits to form a TTL level to control the temporary cardiac pacemaker to issue pacing pulses. When the pulse generator does not sense the TTL level, the pacemaker delivers pacing pulses according to the doctor's parameter settings;...

Problems solved by technology

In addition, the temporary cardiac pacing VVI technology usually takes a long time for clinical treatment, up to more than 10 days, and the temporarily fixed pacing electrodes are mostly in a semi-suspended state in the ventricular cavity, which often leads to the occurrence of pacing electrodes in the cardiac cavity. Displacement, causing sensory failure, false perception and missed perception often occur, seriously affecting the therapeutic effect of temporary cardiac pacing
