本文收集了下壁梗塞时,有、无心脏传导阻滞者各60例,并对两组的病史、临床及死亡原因等进行对照分析。结果示:急性下壁心肌梗塞并发心脏传导阻滞,绝大多数发生在梗塞早期,且大多数能完全恢复,仅少数出院时仍为I°AVB或室内阻滞,其死亡率高于无阻滞组,有统计学意义(P<0.05)。并发房室传导阻滞的主要原因是心脏受累较广泛而严重,多数病人的死亡与严重的心功能障碍有关;但亦有死于心脏无收缩者,此种病人若药物不能提高心率或不能用提高心率的药物时,应考虑安置临时心脏起搏器。心脏传导阻滞消失后,仍应积极改善心功能,病人应逐渐进行体力活动,尽量避免各种应激状态,以免突然增加心脏负荷而导致病人死亡。
This collection of inferior wall infarction, with and without heart block each 60 cases, and the two groups of medical history, clinical and cause of death were compared. The results showed that: the acute inferior myocardial infarction complicated by heart block, the vast majority occurred in the early stage of infarction, and most of them can be fully recovered, only a few were still I AVB or intraventricular discharge when discharged, the mortality rate was higher than no resistance Hysteresis, with statistical significance (P <0.05). Concurrent atrioventricular block is mainly due to heart involvement is more extensive and serious, most of the patient’s death and severe heart dysfunction; but also died of no contraction of the heart, such patients if the drug can not increase the heart rate or can not be used Heart rate of drugs, should consider placing temporary pacemakers. After the disappearance of heart block, should still actively improve cardiac function, patients should gradually physical activity, try to avoid a variety of stress states, so as not to suddenly increase the heart load and cause the patient to die.
