There was first-degree AV block in 5 patients (2.7%) documented by electrocardiogram and in 9 patients(7.6%) revealed during Holter monitoring.
一度房室阻滞经心电图证实为5例（2.7%），经动态心电图监测为9例（7.6%）。
The total number of complication was 72 cases, in which complete AV block and cardiac tamponade accounted for 31.9% (23/72) and 26.4% (19/72) respectively.
并发症共发生72例，其中最多的为完全性房室传导阻滞23例（31。 9% ）和心包填塞19例（26 .4% ）。
RESULTS astemizole could slower the heart rate of mice, prolong P-R and Q-T interphase, even arise the complete AV block and sinus beat stop with the dose increase.
结果阿司咪唑使多数小鼠心率减慢，PR间期和Q T间期延长，随剂量增加，甚至可引起完全性房室传导阻滞和窦性停搏。
Background - Fetal atrioventricular (AV) block is an uncommon lesion with significant mortality.
背景-胎儿房室传导阻滞罕见，但具有极高的病死率。
Roughly around under the surface ECG identified two bypass, bypass atrial fibrillation by alternating two downstream, suggesting that AV conduction block in the right way there.
大致可根据体表心电图确定有左右两条旁路，经两条旁路快速房颤交替下传，提示传导阻滞在房室正道中存在。
