50例慢性房颤患者经动态心电图(DCG)检测发现有2～3秒长间歇者16例(32%)。对这16例作随访,平均时间37±8个月。男女各8例,年龄68±3.6岁。慢性房颤平均时程5.3±1.2年。用DCG 逐个记录和测量长间歇,分析其特点,包括最长间歇的长度(MP),MP 出现的心率及平均心率、每一千个心搏中长间歇出现的频率、以及每小时中长间歇的总数量等。同时观察患者临床状态及洋地黄应用情况。
50 patients with chronic atrial fibrillation by dynamic electrocardiogram (DCG) test found that 2 to 3 seconds long intermittent in 16 cases (32%). Follow-up on these 16 cases, the average time of 37 ± 8 months. 8 males and 8 females, aged 68 ± 3.6 years old. Chronic atrial fibrillation average duration of 5.3 ± 1.2 years. Long periods were recorded and measured one by one with DCG, and their characteristics were analyzed, including the longest intermittent length (MP), the occurrence and the mean heart rate of MP, the frequency of medium and long intervals per one thousand heartbeats, The total number and so on. At the same time observe the clinical status of patients and digitalis application.
