目的:了解心电图在急性右室心肌梗死诊断中的临床应用价值。方法:对43例急性右室心肌梗死患者的跟踪检查资料展开回顾性分析。结果:急性下壁心肌梗死病患再加做右胸V3R-V5R导联检查后发现的右室心肌梗死诊断率是70%;心电图检查可见V1导联ST段升高,V2导联ST段压低的病患确诊作右室心肌梗死的发生率达13.95%;同时,经心电图检查可见Ⅲ导联比Ⅱ导联ST段抬升程度高的病患确诊右室心肌梗死发生率为18.6%,两种检查结果更接近,比较无统计学差异(P>0.05)。结论:当前临床主要采用常规十二导联进行右室心肌梗死的心电图诊断,若有必要需加做右胸导联检查,增强右室心肌梗死诊断准确性,使病患及早得到有效治疗。
Objective: To understand the clinical value of electrocardiogram in the diagnosis of acute right ventricular myocardial infarction. Methods: A retrospective analysis was performed on the follow-up data of 43 patients with acute right ventricular myocardial infarction. Results: The diagnosis rate of right ventricular myocardial infarction was 70% in patients with acute inferior myocardial infarction who were diagnosed with RV-V3R-V5R. ECG of ST segment elevation in V1 lead and ST-segment depression in V2 lead Of patients diagnosed as right ventricular myocardial infarction incidence rate of 13.95%; the same time, the electrocardiogram can be seen in the lead Ⅲ lead than Ⅱ lead ST segment elevation in patients diagnosed with right ventricular myocardial infarction was 18.6%, two The test results were closer, no statistical difference (P> 0.05). Conclusion: The current clinical use of conventional 12 lead ECG diagnosis of right ventricular infarction, if necessary, need to do the right chest lead test to enhance the diagnostic accuracy of right ventricular myocardial infarction, so that patients receive effective treatment as soon as possible.
