据报告急性心肌梗塞病例中有12～25％房室传导阻滞(以下简称房阻),各种房阻的发生在急性下壁心肌梗塞(IMI)时,较前壁心肌梗塞多二至四倍、当急性(IMI)时传导阻滞经常位于房室结,可能适当的近端闭塞是来自房室结动脉,因其在90％病例是从右冠状动脉分枝而来。急性(IMI)以及下列各种症状是被建议应用心脏起搏治疗:阿斯氏征发作,心力衰弱(充血性心力衰竭或休克),以及室性心律不齐引起的心动过
It is reported that 12 to 25% of cases of acute myocardial infarction in atrioventricular block (hereinafter referred to as room resistance), a variety of room resistance occurred in acute inferior wall myocardial infarction (IMI), compared with anterior wall myocardial infarction more than two to four Dorsal, conduction block is often located in the atrioventricular node at acute (IMI) and may be due to proximal atrioventricular nodal artery, as it branches off from the right coronary artery in 90% of cases. Acute (IMI) and the following symptoms are recommended for cardiac pacing: attacks of Asperger, debilitating (congestive heart failure or shock), and bradycardia due to ventricular arrhythmias
