心房扑动(AF)的扑动波(F)频率一般为250～400次/分,以300～350次/分较为多见;而F波频率低于200次/分的AF目前尚少见报道。现将我院所见2例(本文暂称为“慢频率型”AF)报告如下。临床资料 2例患者均为男性,年龄分别为72岁和79岁。 (1) 病因:2例患者临床诊断均为冠心病,病程均在20年以上。 (2) 出现AF时心电图特点:F波频率分别为188次/分、200次/分,房室传导比例2:1～4:1,在不同导联中出现有ST-T改变;房扑发生的起止状况:
Atrial flutter (AF) flutter wave (F) frequency is generally 250 to 400 beats / min to 300 to 350 beats / min more common; and F wave frequency less than 200 beats / min AF is still rarely reported . Now see in our hospital 2 cases (this article is referred to as “slow frequency type AF”) reported as follows. Clinical data 2 patients were male, aged 72 and 79 respectively. (1) Etiology: 2 cases of patients with clinical diagnosis of coronary heart disease, duration of more than 20 years. (2) The appearance of AF ECG characteristics: F wave frequency of 188 beats / min, 200 beats / min, atrioventricular conduction ratio of 2: 1 ~ 4: 1, appear in different lead ST-T changes; atrial flutter Occurrence of starting and ending conditions:
