Electrophysiology technology is used to measure, record and dissect the electrical marvels and characteristics of organisms, while cardiac electrophysiology refers to the comprehensive judgment and corresponding treatment by recording the electrical exertion in the heart, assaying its performance and characteristics to reason. Besides routine medicine control, electrophysiological surgery can't only control arrhythmia symptoms and ameliorate the quality of life, but also ameliorate the prognostic and reduce the prevalence of stroke, cardiovascular events and death.

Cardiac electrophysiological surgery includes two-dimensional cardiac electrophysiological surgery and three- dimensional cardiac electrophysiological surgery. Compared with two- dimensional cardiac electrophysiology surgery, three- dimensional cardiac electrophysiology surgery has egregious specialized advantages, substantially including high mapping viscosity, accurate catheter positioning, short mapping time, low- cure radiation,etc., which can ameliorate the success rate of surgery and reduce the radiation damage to cases and croakers, and is gradationally replacing two- dimensional technology.
Catheter ablation are the main treatment for arrhythmia surgery. There are three products involved in catheter radiofrequency ablation surgery, videlicet, three- dimensional mapping system, mapping catheter and ablation catheter. Simply put, the three- dimensional mapping system and mapping catheter are used to collude and model the heart, measure the original electrical signals and pacing of the heart and find the position of the lesion, and also the ablation catheter is used to ablate the lesion( the myocardial towel is clotted and necrotic by heating). Ablation also includes radiofrequency ablation and cryoablation. At present, the effectiveness of radiofrequency ablation for fairly simple supraventricular tachycardia, similar as binary atrioventricular nodal pathways and atrioventricular reentry, with clear medium, can reach about 95( generally refers to one- timenon-recurrence), and the success rate for ferocious atrial fibrillation can reach about 90, while the effective rate for patient atrial fibrillation is only about 70. The increase in the driver's operating experience and the nonstop preface to new products is anticipated to continuously ameliorating the operative effectiveness. Croakers need a certain literacy wind and the popularization and popularization of the three- dimensional system.
Excellent damping, coetaneous beating with the heart, stable contact and delicate relegation.
Soft head end to avoid myocardial towel damages.
A variety of electrodes distance, furnishing demarcation of ECG signals to specific corridor. It must be strong and full signals diagnostic electrophysiology catheter.
The hardness of the catheter is gradationally changed from the electrode section to the main body of the catheter, which improves the project and the in- place capability of the catheter.
