目的：描述室颤复苏初始阶段的心律变化，与虚脱和除颤之间的间隔、存活和旁观者启动的心肺复苏（CPR）有关。患者：1980年至1992年期间发生院外心脏骤停的所有患者，他们通过紧急医疗服务系统（EMS）获得，其中开始复苏尝试并发现室颤。结果：共有1216例患者纳入研究。在首次除颤后转为脉冲发生心律的患者中（n = 119），56%的患者出院，而转为心搏停止的患者中有6%出院。第三次除颤后的相应数字分别为49%和2%，第五次除颤后分别为28%和7%。在第一次除颤发生在崩溃后不到5分钟的患者中，28%的患者直接转换为脉冲发生节律，而在第一次除颤发生在崩溃后12分钟或更长时间的患者中，只有3%的患者直接转换为脉冲发生节律。结论：在院外心脏骤停并发现室颤的患者中，除颤后的存活率与初始心律变化之间存在很强的关系。这些节律变化与塌陷和第一次除颤之间的间隔直接相关。(C)1997 Elsevier Science爱尔兰有限公司
Aim: To describe rhythm changes during the initial phase of resuscitation from ventricular fibrillation in relation to the interval between collapse and defibrillation, to survival and to bystander-initiated cardiopulmonary resuscitation (CPR). Patients: All patients who suffered out-of-hospital cardiac arrest between 1980 and 1992, who were reached by the emergency medical service system (EMS), in whom resuscitation attempts were initiated and who were found in ventricular fibrillation. Results: In all, 1216 patients were included in the study. Among patients who converted to a pulse-generating rhythm after the first defibrillation (n = 119) were 56% discharged from hospital as compared with 6% among patients who converted to asystole. The corresponding figures after the third defibrillation were 49% and 2%, respectively, and after the fifth defibrillation 28% and 7%, respectively. Among patients in whom the first defibrillation took place less than 5 min after collapse, 28% directly converted to a pulse-generating rhythm as compared with 3% when the first defibrillation took place 12 min or more after collapse. Conclusion: Among patients who suffer out-of-hospital cardiac arrest and are found in ventricular fibrillation, there is a strong relationship between survival and initial rhythm changes after defibrillation. These rhythm changes are directly related to the interval between collapse and the first defibrillation. (C) 1997 Elsevier Science Ireland Ltd.
