Abstract

The invention relates to the technical field of medical instruments, in particular to a method for improving the electroporation effect and a preheating pulse ablation system. According to the method for improving the electroporation effect, a preheating pulse ablation system is included, compared with the prior art, the method for improving the electroporation effect and the preheating pulse ablation system are provided, and target biological tissue is preheated through intracardiac radio frequency ablation (RFA), so that cell activity is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method for improving the effect of electroporation and a preheating pulse ablation system. Background technique [0002] The heart acts like a pump to promote the normal operation of blood circulation in the human body. It automatically and rhythmically sends electrical signals to various parts of the heart through the sinoatrial node, causing the atrial and ventricular muscles to contract and relax according to a certain rhythm to promote blood flow. When the generation and conduction of electrical signals are abnormal, the heartbeat will be too fast, too slow or irregular, which is called arrhythmia. At present, in clinical practice, radiofrequency ablation is widely used to treat the problem, and blocks the transmission of abnormal ECG signals by removing myocardial tissue at a specific location. [0003] Intracardiac radiofrequency ablation (RFA) is to push the el...
