随着新型电解剖定位系统及人类心房正常传导的计算机模型的开发成功〔1〕,人们对窦房结的结构功能、窦性激动的起源及在心房的传导有了更深刻的认识,并对病理状态下窦房结的功能状态能够进行深入研究。在老年人及窦房结疾病、房性心律失常、心力衰竭、先天性心脏病等疾病中观察 With the success of the development of a new computerized model of electroanatomic location system and normal conduction of human atria, people have a deeper understanding of the structural function of sinus node, the origin of sinus excitability and conduction in the atrium The pathological status of the sinus node functional status can be further studied. In the elderly and sinus node disease, atrial arrhythmia, heart failure, congenital heart disease and other diseases observed
