急性下壁心肌梗塞常累及右心室,从而影响其预后。本文就心电图VR导联ST段抬高作为下壁心肌梗塞预后指标的可靠性进行临床研究。方法:200例急性下壁心肌梗塞住院病例,其中男性153例,女性47例,年龄35～91岁,平均63.5±6岁。诊断标准:典型胸痛持续30分钟以上;心电图Ⅱ、Ⅲ、aVF导联中不少于二个导联的ST段抬高≥0.1mV;入院24小时内肌酸磷酸激酶(CK)测值达正常值2倍以上(>140单位/升)。全部患者均作标准12导联心电图及右心导V_3R-V_6R。对照方法选用尸解、冠状血管造影及右室或双室造影、~(99-)Tc核素扫描、以及右心压力监测血液动力学改变.
Acute inferior myocardial infarction often involves the right ventricle, thus affecting its prognosis. In this paper, ECG lead VR ST segment elevation as a prognostic indicator of myocardial infarction reliability of clinical research. Methods: 200 cases of acute inferior myocardial infarction hospitalized cases, including 153 males and 47 females, aged 35 to 91 years, mean 63.5 ± 6 years. Diagnostic criteria: typical chest pain for more than 30 minutes; ECG Ⅱ, Ⅲ, aVF leads more than two ST-segment elevation lead ≥ 0.1mV; within 24 hours after admission creatine phosphokinase (CK) measured as normal More than 2 times value (> 140 units / liter). All patients were as standard 12-lead ECG and right heart V_3R-V_6R. The control method was autopsy, coronary angiography, right ventricle or double-chamber angiography, ~ (99-) Tc nuclide scan, and right heart pressure to monitor hemodynamic changes.
