右室心肌梗死与心电图改变

The Right Ventricular Myocardial Infarction and Electrocardiogram Change

多年来右室心肌梗死 (RVI)在临床报告中不多见 ,但近年来右室心肌梗死逐渐引起广泛重视 ,心电图对右室心肌梗死早期做出明确的诊断 ,对于右室梗死的治疗和愈后十分重要。心电图是诊断心肌梗死的常规检查方法 ,具有简便、迅速、无创、实用价值强等优点。由于右胸导联ST段上移幅度低 ,持续时间短 ,恢复较快 ,异常Q波假性出现率高 ,加之未加做右胸导联或就诊不及时而容易漏诊 ,给临床诊断、治疗带来一定困难。采用心电图V4R导联ST段上移≥ 0 .1mV诊断右室心肌梗死 ,经过统计发现 ,右室心肌梗死的发生率约在 7% 2 3%。

The right ventricular myocardial infarction has been actually r are in the clinical report for many years,but the right ventricular myocardial i nfarction causes the extensive attention gradually in recent years,making clear diagnosis to the right ventricular myocardial infarction in early days in electr ocardiogram,the treatment and prognosis of the right ventricular myocardial infa rction are very important.Electrocardiogram diagnose routine inspection method o f myocardial infarction, have simple and convenient,rapidly,unscathed,practical value getting better advantage.Because right chest lead ST segment elevation the range low on section,duration is short,it is very fast to resume,the false appe aring rate of unusual Q wave is high,in addition it does not do the right chest lead or not go to a doctor in time and apt to leak to be examined, it is difficu lt to bring to clinical diagnosis,treatment and is sure. Adopt electrocardiogram V 4R lead and unite ST segment elevation≥0.1 mV and diagnose the right ve ntricular myocardial infarction,through counting and find,about 7 %~23 % of inc idence of the right ventricular myocardial infarction.
