一、定义：病窦综合征最初由Lown氏命名，该氏对心房颤动以电去颤后未恢复窦性节律而出现的种种房性节律，认为是由于窦房结的冲动产生异常或窦一房传导障碍所致。目前一般认为病窦综合征包括以下若干类型：①窦性及房性活动均停止；②窦一房阻滞；③心房颤动去颤后未恢复窦性节律，④显著窦性心动过缓，⑤非药物所致慢性心 First, the definition: Sick sinus syndrome was originally named Lown ’s, the’ s atrial fibrillation after electrical defibrillation did not resume sinus rhythm and the emergence of a variety of atrial rhythms that are due to sinus node impulse abnormalities or sinus Room conduction disorder caused. At present, it is generally considered that several types of sick sinus syndrome include the following: (1) sinus and atrial activity are stopped; (2) sinus blockage; (3) sinus rhythm is not restored after defibrillation of atrial fibrillation; (4) significant sinus bradycardia Non-drug-induced chronic heart
