Sudden death, defined as the death that occurs naturally, unexpectedly and instantaneously or within the first hour of the onset of premonitory symptoms, is one of the most important challenge of the modern cardiology. This is due to both, its elevated incidence (400,000 to 500,000 cases per year in United States alone) and its dramatic presentation (many of the victims are relatively young and have an acceptable quality of life). We have studied de Holter tapes of 233 patients who died suddenly and we can demonstrate that 80% of cases were due to ventricular tachyarrhythmias (ventricular fibrillation 60% and torsades de pointes 20%) and the rameinens 20% were due to bradyarrhythmias. It is well known that ischemic heart disease is the leading cause of sudden death, being responsible for more than 80% of cases. In the present article we will analyze the relationship between sudden death and the different types of ischemic heart disease: stable angina pectoris, unstable angina pectoris, acute myocardial infarction and postinfarction and silent myocardial ischemia.
猝死定义为自然发生、意外且瞬间或在先兆症状出现后第一小时内发生的死亡，是现代心脏病学面临的最重要挑战之一。这是由于其发病率高（仅在美国每年就有40万至50万例）以及其表现惊人（许多受害者相对年轻且生活质量尚可）。我们研究了233例猝死患者的动态心电图记录，结果显示80%的病例是由室性快速心律失常（室颤占60%，尖端扭转型室速占20%）引起的，其余20%是由缓慢性心律失常引起的。众所周知，缺血性心脏病是猝死的主要原因，占病例的80%以上。在本文中，我们将分析猝死与不同类型缺血性心脏病之间的关系：稳定型心绞痛、不稳定型心绞痛、急性心肌梗死、心肌梗死后和无症状心肌缺血。
