病态窦房结综合征(病窦)多由窦房结(SAN)和心房(A)的退行性变所引起,常波及房室结(AVN)、希氏束或束支。诊断以心律失常为依据,症状作参考。一.诊断(一) 心电图有下列之一者即可诊断:①明显持久的窦缓(<50bpm),经运动或用阿托品后不能正常增快;②窦性心动过缓兼有SA阻滞、窦性停搏,逸搏出现缓慢;③阵发性SVT、房颤(Af)、房扑(AF)发作终止后,窦性心律恢复缓慢(>1.5s),
Sick sinus syndrome (sick sinus) and more by the sinus node (SAN) and atrial (A) degeneration caused by the constant and atrioventricular node (AVN), His bundle or bundle branch. Diagnosis based on arrhythmia, the symptoms for reference. A diagnosis (A) one of the following ECG can be diagnosed: ① significant and lasting sinus slow (<50bpm), after exercise or with atropine can not be normal faster; ② sinus bradycardia both SA block, Sinus bradycardia, escape appear slow; ③ paroxysmal SVT, atrial fibrillation (AF), atrial flutter (AF) termination of the attack, sinus rhythm recovery is slow (> 1.5s)
