理想的心脏起搏刺激应包括直接和唯一夺获传导系统近端而无心室和心房感知与夺获,不影响瓣膜功能,克服引起束支传导阻滞或电机械失偶联的束支远端和浦肯野纤维病变。本回顾性分析将对传导系统的功能解剖、现有的特殊起搏部位命名、各种为求达到理想传导系统起搏所用方法的利与弊进行讨论。房室传导系统的解剖和生理房室结和慢径心肌位于Koch氏三角内。该三角由直达 Ideal cardiac pacing stimuli should include both direct and unique acquisition of the proximal end of the conduction system without the perception and capture of the ventricles and atria, without affecting the valvular function, overcoming the distraction of the bundle branch causing bundle branch block or electromechanical misdiagnosis And Purkinje fiber lesions. This retrospective analysis discusses the functional anatomy of the conduction system, the naming of existing special pacing sites, and the pros and cons of various approaches used to achieve optimal conduction system pacing. Anatomical and Physiologic AV Transes Atrioventricular node and slow pathway myocardium are located within the Koch triangle. The triangle by the direct
