Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for cooperating with a high-voltage electric pulse ablation and an electrophysiological recorder. Background technique [0002] Atrial fibrillation (AF) is the most common cardiac arrhythmia, with an incidence of about 2%, and its incidence gradually increases with age. The most serious complication of AF is thromboembolism, which can lead to stroke and myocardial infarction, among which stroke is the most common complication of AF death. [0003] There are two broad categories of treatments for atrial fibrillation, drug treatments and non-drug treatments. According to "Atrial Fibrillation: Current Understanding and Treatment Suggestions-2015" published by the Cardiac Electrophysiology and Pacing Branch of the Chinese Medical Association, the current drug treatment of atrial fibrillation mainly includes: controlling the ventricular rate, restoring and maintaining sinus rh...

Problems solved by technology

The most commonly used method for electrophysiological ablation today is to connect a mapping catheter to observe, collect, display and store cardiac electrophysiological signals during electrophysiological ablation in real time through an electrophysiological recorder. This has the following disadvantages: the mapping catheter cannot measure the actual ablation There is a certain deviation between the ECG signal at the tissue location and the actual ablated tissue location; the high-voltage electrical pulse signal will enter the electrophysiological recorder, causing the ECG signal to be interfered and cannot reflect the real ablation effect; the high-voltage electrical pulse signal entering the electrophysiological recorder Physiological recorder may damage electrophysiological recorder
