电生理检查心肌电生理检查对心律失常发病原理的认识、诊断分析的提高及防治措施的发展具有重要意义,目前,这方面的工作开展较快。希氏束电图既是房室传导障碍最可靠的定位手段,亦是电生理检查的必要部分。西安自制9极导管,只用一根导管即可完成记录希氏束电图及刺激心脏。评定不应期是深入了解正常和病 Electrophysiological examination of myocardial electrophysiological examination on the pathogenesis of arrhythmia understanding, diagnosis and analysis of the development and prevention and control of the development of great significance, at present, the work carried out in this area faster. His bundle beam is not only the most reliable means of localization of atrioventricular conduction, but also an essential part of electrophysiology. Xi’an self-made 9-pole catheter, only one catheter can be completed record His bundle and stimulate the heart. Assessment of refractory period is a deep understanding of normal and sick
