Problems solved by technology

However, when the lead falls off while the patient is wearing a temporary pacemaker, it cannot be detected automatically. It needs to be judged by naked eyes or by observing the waveform of the patient's ECG signal with the help of an electrocardiogram machine. detrimental to patient safety

Abstract

The invention relates to a pace-making lead shedding detection method and a temporary cardiac pacemaker. The method comprises the following steps: forming a pace-making pulse by discharging by a pace-making capacitor, and obtaining an impedance value of a pace-making system according to the discharge duration, the initial voltage at two ends the pace-making capacitor before discharge, the end voltage at two ends of the pace-making capacitor after discharge, and the capacitance value of the pace-making capacitor. , and determining whether the pace-making lead is shed or not depends on whether the impedance value is outside the normal interval. The method solves the problem that the lead is detached and a pace-making circuit is disconnected when the pacemaker is used, and the disconnection is not easy to find in time, the pacemaker helps the doctor to respond quickly to the pace-making lead shedding, and the patient's safety is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a method for detecting the falling off of a pacing lead and a temporary cardiac pacemaker. Background technique [0002] When a clinical patient is using a temporary pacemaker, venipuncture is first performed on the patient's lower extremity to draw out the pacing lead, and then the external pulse transmitter of the temporary pacemaker is connected to the pacing lead, and then the pulse transmitter emits energy provided by the battery Through the conduction of the pacing lead, the electrical pulse stimulates the myocardium in contact with the electrode, so that the heart is excited and contracted, so as to achieve the purpose of treating cardiac dysfunction caused by some arrhythmias. However, when a patient wears a temporary pacemaker, it cannot be automatically detected when the lead falls off. It needs to be judged by visual observation or by observing the patient's ECG signal...
