急性心肌梗塞(AMI),是内科常见急症之一,急性期病死率高。不仅发生于中老年人,青壮年也有发生,发病年龄有逐渐年青趋势。 AMI最常见的死亡原因为严重心律失常和泵衰竭,二者可相互影响与并存,对突发性的心律失常不易察觉,因而大部分成为猝死的原因。据一些统计资料表明:约50％病人未到达医院即已死亡,其中大部分是发病后一小时内。住院病死率过去30～40％左右,其中65％死于头三天,85％死于第一周。近十余年来由于AMI治疗的迅速进展,尤其在有条件的大医院设立“冠心病监护室”(CCU)与电子监护系统如24小时动态心电图(Holter)的临床应用,从而使住院病死率下降至12～15％。本文将重点讨论AMI中心律失常的紧急处理原
Acute myocardial infarction (AMI), is one of the common medical emergency, high mortality in acute phase. Not only occurs in the elderly, young adults have also occurred, the age of onset of a gradual young trend. The most common cause of death in AMI is severe arrhythmia and pump failure, which can interact with each other and coexist. Sudden cardiac arrhythmia is not easily detected, and most of the causes of sudden death. According to some statistics, about 50% of patients died before they reached the hospital, most of them within an hour after onset. In-hospital mortality in the past 30 to 40%, of which 65% died in the first three days, 85% died in the first week. In the recent ten years, due to the rapid progress of AMI treatment, the clinical application of “coronary care unit” (CCU) and electronic monitoring system such as 24-hour Holter has been set up especially in large hospitals with conditions so that in-hospital mortality Decline to 12 ~ 15%. This article will focus on the AMI arrhythmia emergency treatment of the original
