There were 1323 deaths due to ischaemic heart disease in Belfast from 20 July 1981 to 19 July 1982. Some 496 (37%) of these were in persons aged less than 70 years. By World Health Organisation criteria 247 (19%) of these deaths were classified as definite myocardial infarction and 749 (57%) as possible myocardial infarction. Dyspnoea, collapse, and typical pain were the main symptoms at the onset of the fatal attack. In hospital only 12% of deaths in persons aged less than 70 years and 14% of those aged greater than or equal to 70 years were due to presumed primary rhythm disturbance, whereas outside hospital these proportions were 78% and 59% respectively. The median survival time was 84 minutes and was shortest in men aged less than 70 years (62 minutes). Outside hospital a relative was the most likely aid sought initially (70%) and the median delay time from onset of symptoms to calling for medical aid was eight minutes. Among 128 witnessed deaths in persons aged less than 70 years occurring outside hospital due to presumed primary rhythm disturbance the median survival time was 8 X 25 minutes. Improvements in facilities available for resuscitation including public education could result in the prevention of a proportion of deaths caused by primary rhythm disturbances.
1981年7月20日至1982年7月19日期间，贝尔法斯特有1323人死于缺血性心脏病。其中约496人（37%）年龄小于70岁。根据世界卫生组织的标准，这些死亡病例中247例（19%）被归类为确诊心肌梗死，749例（57%）为可能的心肌梗死。呼吸困难、虚脱和典型疼痛是致命发作开始时的主要症状。在医院里，年龄小于70岁的患者中只有12%的死亡以及年龄大于或等于70岁的患者中14%的死亡是由推测的原发性节律紊乱导致的，而在医院外，这些比例分别为78%和59%。中位生存时间为84分钟，在年龄小于70岁的男性中最短（62分钟）。在医院外，最初最有可能寻求帮助的是亲属（70%），从症状出现到呼叫医疗救助的中位延迟时间为8分钟。在128例年龄小于70岁、在医院外因推测的原发性节律紊乱而死亡且有目击证人的病例中，中位生存时间为8×25分钟。改善包括公众教育在内的可用复苏设施，可能会预防一部分由原发性节律紊乱导致的死亡。
