心律失常是小儿心血管疾病常见的一种表现。近年来有关这方面的资料日见增多。说明对本病在理论上和技术上均有了新的认识和新的发展。一、心律失常的概述正常心脏冲动起源于窦房结,按一定的频率、速度和一定的程序传布激动至心房与心室。从解剖生理学角度来讲,心律失常主要是产生冲动和传导冲动系统发生障碍的结果。故心律失常归纳为两大类:(一)冲动起源异常引起:(窦房结以下的异位节律点释放)1.各种过早搏动:房性、结性和室性。
Arrhythmia is a common manifestation of pediatric cardiovascular disease. In recent years, there has been an increase in information in this area. Explain the disease in theory and technology have a new understanding and new development. First, the overview of arrhythmia Normal cardiac impulse originated in the sinus node, according to a certain frequency, speed and certain procedures spread excited to the atria and ventricle. From an anatomical and physiological point of view, arrhythmias are mainly the result of impulsive and impulsive conduction impulsive systems. Therefore, arrhythmia can be summarized into two categories: (A) caused by the origin of impulse: (sinus node ectopic rhythm release following) 1. A variety of premature beats: atrial, nodular and ventricular.
