急性心肌梗死(AMI)是一种严重威胁中老年人生命的心血管急症,其特点是发病急,进展快,病死率高。确诊后应尽早抢救,保护心肌,缩减梗死范围。因此,快速有效的院前急救,安全平稳的途中监护以及相关医院的专科特色治疗构成了成功抢救患者、降低死亡率的有效链条。而要保证该链条的高效运转与衔接,需要具有现代先进科学技术的院前急救通讯指挥系统。武汉市急救中心于2001年引进了120通讯指挥调度系统。2003年对整个系统进行了改建使之成为更具现代化的通讯指挥系统。本研究通过对比引进该系统前后相关时间段和 Acute myocardial infarction (AMI) is a cardiovascular emergency that is a serious threat to the life of the elderly, characterized by acute onset, rapid progression, and high case fatality. After the diagnosis should be rescued as soon as possible, protect the myocardium, reduce infarct size. Therefore, fast and effective pre-hospital care, safe and stable en-route care, and special hospital related specialties constitute an effective chain to successfully rescue and reduce mortality. To ensure the efficient operation and connection of this chain, a pre-hospital emergency communications command system with modern advanced science and technology is needed. Wuhan City Emergency Center in 2001 introduced a 120 communications command and dispatch system. In 2003 the entire system was rebuilt to make it a more modern communications system. This study compares the time period before and after the introduction of the system
