急性下壁心肌梗死伴胸前导联ST段压低对老年患者近期预后的影响

Short-Period Prognostic Effect of Gerontal Patients With Acute Inferior Wall Myocardial Infarction With Depressed Precordial Leads ST Segement

目的探讨急性下壁心梗伴胸导ST低电压对老年患者预后影响。方法选择ST低电压25例,设对照组22例,描记常规12导联ECG,后壁导联V7~9,为胸导联V3R^V5R,测量各导联ST所指高和低压幅度,下壁导联ST段至少有2个指抬高>1.0mm,V1~V4导联至少有2个导联ST压低>1.0mm。结果A组心梗后心绞痛11例,多形性室早8例,心功不全Ⅱ级10例,死亡4例。B组(对照组)心绞痛4例,室早2例,心功不全Ⅱ级3例,死亡0例。结论胸前导联ST段压低的急性下壁心梗病人预后不良。

Objective To study the short - period prognostic effect of gerontal patients with acute inferior wall myocardial infarction with depressed precordial leads ST segement, method Select 25 patients with depressed precordial leads ST segement as research group and 22 patients as control group. Trace normal 12- lead ECG, posterior wall V7 - V9, right chest V3R- V5R. Measure the elevated and depressed amplitude of every lead.At least 2 leads of inferior wall with ST- segement 〉 1 mm and V1 - V4 leads〉 1 mm. Rusult In the A group, there were 11 patients with postinfaretion angina ,8 with multiple ventricular beat, 10 with cardia dysfunction classⅡ ,4 death. In the control group,4 with angina,2 with multiple ventricular beat,3 with cardia dysfunction class Ⅱ ,0 death. Conclusion The patients with acute inferior wall myocardial infarction with depressed precordial have a unfavourable prognosis.
