已知溶栓疗法((?))是拯救濒死心肌最有前途的方法之一,其疗效的好坏则取决于(?)的开始时间,愈早愈好。本文就心肌梗塞((?))时住院前及住院阶段的TJIT进行比较。方法:选择对象应符合以下条件:(?)为原发性,年龄不超过70岁,典型血管性发作至少持续30min,住院前及住院阶段(?)时间分别在起病后2h和5h内。心电图应符合:STv_1~-v_4~-抬高≥0.3mV,STⅠ、Ⅱ或v_5-v_6~-抬高≥0.2mV;下壁(?)时STⅠ、Ⅱ抬高≥0.1mV或STv_1~～v_4~-降低≥0.2mV。有下列情况者除外:心肺复苏后,有出血倾 Thrombolytic therapy ((?)) Is known to be one of the most promising ways to rescue dying myocardium, and its efficacy depends on the onset of (?) As soon as possible. This article compares myocardial infarction ((?)) With pre-hospital and in-hospital TJIT. Methods: Subjects should meet the following conditions: (?) Primary, age less than 70 years old, typical vascular episodes lasts at least 30min, pre-hospital and hospitalization (?) Time were onset within 2h and 5h. ECG should be consistent with: STv_1 ~ -v_4 ~ - elevated ≥ 0.3mV, ST Ⅰ, Ⅱ or v_5-v_6 ~ - elevation ≥ 0.2mV; ST Ⅰ, Ⅱ lower wall (?) Elevation ≥ 0.1mV or STv_1 ~ ~ v_4 ~ - Reduce ≥0.2mV. Except for the following cases: after cardiopulmonary resuscitation, bleeding dumping
