急性下壁心肌梗死的心电诊断分析

吴鹏

目的 探讨心电图在急性下壁心肌梗死诊断中的效果及价值。方法 根据病变部位将我院于2015年1月～2016年1月收治的60例急性下壁心肌梗死患者分为两组，左回旋支出现病变情况的观察组（20例）和右冠状动脉出现病变情况的对照组（40例），分析两组患者的心电图特点。结果 对照组在Ⅰ导联ST段压低或者水平、aVL导联ST段同时压低、ST段抬高水平Ⅲ大于Ⅱ导联方面敏感性和特异性更加明显，观察组在Ⅰ导联ST段抬高、ST段抬高水平Ⅲ小于Ⅱ导联方面敏感性和特异性更加明显。结论 对急性下壁心肌梗死患者进行心电图诊断，效果良好，准确率高。

【Abstract】

Objective To make an investigation on effect and value of ECG（electrocardiogram）in diagnosis of patients with acute inferior myocardial infarction （AIMI）. Methods From January 2015 to January 2016，chose 60 patients with acute inferior myocardial infarction（AIMI）who were treated in hospital and separated them into two groups. 20 patients with left circumflex artery lesion were separated into study group and 40 patients with right coronary artery lesion were separated into control group，and then make an analysis on patients’ ECG characteristics between two groups. Results Patients’ ECG image in control group showed that it was depressed in ST-segment of I-lead and ST-segment of Avl-lead，and sensitivity and specificity of segment III elevation were more than those of segment II. Patients’ ECG image in study group showed that it was elevated in ST-segment and sensitivity and specificity of segment III elevation were less than those of segment II. Conclusion ECG（electrocardiogram）is quite effective and accurate in diagnosis of patients with acute inferior myocardial infarction（AIMI）.

急性下壁心肌梗死是由心脏冠状动脉闭塞、持续性缺血缺氧引起的心肌坏死，该疾病并发症较多，主要有心力衰竭、心律失常等［1］，严重威胁患者的生命安全和身体健康，因此，需要在患病初期给予患者更加有效地诊断，方便制定出更加合理的治疗方案。本文以我院近期收治的急性下壁心肌梗死患者为研究对象，给予他们心电图诊断方法，取得了较好的诊断效果，具体过程如下。

1　资料和方法

1.1一般资料

我院于2015年1月～2016年1月收治60例急性下壁心肌梗死患者，按照病变位置分为两组。观察组患者20例，男性12例，女性8例，年龄36～75岁，平均年龄（57.4±3.1）岁；对照组患者40例，男性23例，女性17例，年龄38～76岁，平均年龄（58.2±3.5）岁。经检查，两组患者均存在持续性胸痛症状，其年龄性别、年龄及病情状况等一般资料差异不具有统计学意义（P＞0.05），具有可比性。……
