各种原因引起的高度或完全性房室传导阻滞,常发生急性心源性脑缺血综合征,其死亡率极高。对这类病人必须进行积极的抢救,但往往药物治疗难以凑效,安置心脏起搏器是治疗该病的一项有效措施。在危急的情况下或一些不需长期起搏的患者给予临时起搏常可收到预期效果,使病者转危为安。近年来,我们用临时起搏(用双电极导管由静脉插入至右心室近心尖部,另端引出体外连接上海 AXQ—1型携带式R—抑制型按需心脏起搏器),抢救了2例因冠心病致高度和完全性房室传导阻滞倂发急性心源性脑缺血综合征或头晕,经人工起搏后(1例安置4天,1例为 A variety of causes of a high degree or complete atrioventricular block, often occur in acute cardiogenic cerebral ischemic syndrome, the mortality rate is extremely high. For such patients must be actively rescued, but often difficult to cope with drug treatment, placement of pacemakers is an effective measure to treat the disease. Provisional pacing in patients in critical situations or in patients who do not require long-term pacing often receives the expected results, putting patients at risk. In recent years, we have used temporary pacing (double-catheter catheterization from the vein to the apical part of the right ventricle, the other end leads to in vitro connection Shanghai AXQ-1 portable R-suppressed on-demand cardiac pacemaker), the rescue of 2 Cases due to coronary heart disease caused by a high degree and complete atrioventricular block 倂 issued acute cardio-cerebral ischemic syndrome or dizziness, after artificial pacing (1 case for 4 days, 1 case
