Abstract

The application relates to the field of a medical apparatus, in particular to a method for improving safety ventricular pacing reliability, a circuit, a storage medium and a device. The method for improving safety ventricular pacing reliability comprises the steps of obtaining average characteristic value of PVC waves and QRS waves; creating a detection window of the PVC waves and the QRS waves; comparing the characteristic value of collection waves with the characteristic value in the window, if yes, triggering VSP pulse, or else, emitting the pulse VP after AVI; and if the VSP pulse for M times is triggered by the QRS waves, enabling the percept sensitivity of the atrium of the heart to be increased by one class. Besides, the application further provides a circuit and device for realizing the method. The relevance of the characteristic value and the average characteristic value of the PVC waves and the QRS waves is detected through a created detection window, the VSP pulse is furtheraccurately triggered, the percept sensitivity of the atrium of the heart is adjusted, the number of times that the VSP is triggered or restrained by errors is reduced, and the VSP triggered reliability is improved.

Description

technical field [0001] The present application relates to the field of medical devices, in particular, to a method, circuit, storage medium and device for improving the reliability of ventricular safe pacing. Background technique [0002] The number of patients implanted with dual-chamber pacemakers has shown a steady increase in recent years. VSP (Ventricle Safety Pacing: Ventricle Safety Pacing) function is a basic function necessary for dual-chamber pacemakers, and its purpose is to ensure the safety of ventricular pacing. [0003] The VSP pulse is not a ventricular pulse that is routinely delivered by a dual-chamber pacemaker, it is only triggered under specific circumstances. The VSP function is within 100ms after the AP is released. If the ventricular sensing circuit senses any electrical signal, the pacemaker will send a VSP pulse at 100ms. The strength of the electrical signal sensed by the ventricular channel will change, and the time limit of the far-field signal...
