Intracavity electrocardiosignal processing and display method and temporary cardiac pacemaker having function

Abstract

The invention discloses an intracavity electrocardiosignal processing and display method and a temporary cardiac pacemaker having the function. The intracavity electrocardiosignal processing and display method includes the following steps: acquiring an intracavity electrocardiosignal; pre-processing the intracavity electrocardiosignal; storing the pre-processed intracavity electrocardiosignal in real time; detecting if a pace-making parameter adjustment command is triggered or not, and entering the next step if so; and invoking and displaying the intracavity electrocardiosignal which is storedin real time on a pace-making parameter adjustment interface in the same screen. The temporary cardiac pacemaker acquires the intracavity electrocardiosignal, pre-processes the intracavity electrocardiosignal, performs electrocardio event marking, electrocardiosignal intercepting or electrocardiosignal sampling, and then makes a corresponding display response according selection. In displaying, the temporary cardiac pacemaker can display real-time continuous electrocardiosignal or display a wave signal having a single electrocardio event having rich detail information, can indicate the current perception sensitivity, and can allow a user to rapidly make a determination and adjust the corresponding parameter.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a method for processing and displaying intracavity electrical signals and a temporary cardiac pacemaker with the function. Background technique [0002] In some patients, due to slow heart rate, arrhythmia, weakened heart contractility, reduced blood pump volume, insufficient blood perfusion of various organs of the body, ischemia and hypoxia cause functional failure, the heart may stop beating at any time, endangering the life of the patient. Placement of a temporary cardiac pacemaker in bedside emergency can immediately increase the heart rate and improve ischemia and hypoxia. It is the most effective and safest way to rescue patients and the most direct way to increase the patient's heart rate. A temporary cardiac pacemaker stimulates the myocardium by sending out pulsed electrical signals, causing the heart to contract, thereby replacing the original cardiac pacemaker and con...

Problems solved by technology

However, the traditional temporary cardiac pacemaker only has the function of pacing output. The operator cannot timely check the current actual intracavity electrocardiographic signal acquisition through the temporary cardiac pacemaker. Signal inferred pacing capture

Moreover, it is impossible to judge whether the electrode of the implanted pacing lead predicts that the long-term implantation will be good through the surface ECG signal provided by the external ECG monitor.

The operation and use of the traditional temporary cardiac pacemaker must be used with the help of an external ECG monitor. There is no simple operation method for providing temporary pacing and observing the intracavity electrical signal function at the same time with a single instrument, which reduces the work efficiency and cannot accurately judge whether it is captured or not. No, it is impossible to judge whether the implanted pacing lead can predict good long-term implantation, which greatly reduces the accuracy and real-time performance of the instrument judgment
