心电图ST段压低对急性肺栓塞栓塞面积诊断价值
打开文本图片集
[摘 要] 目的:分析急性肺栓塞(APE)患者心电图ST段压低情况,探讨其与栓塞面积相关性。方法:选择128例APE患者为研究对象,按照是否出现ST段压低分组,分析两组患者栓塞面积、死亡率等指标的差异。结果:128例APE患者中,有72例患者出现心电图ST段压低,发生率为56.25%,较大面积组的aVF、V2、V6导联ST段压低发生率高于小面积组(P<0.05),大面积组的Ⅲ、aVL、aVF、V1、V6导联ST段压低发生率高于小面积组(P<0.05),大面积组Ⅲ、aVL、V1、V2导联的ST段压低发生率高于较大面积组(P<0.05)。ST段压低组与非压低组比较,休克发生率为4.05%vs3.7%,死亡率为8.11 %vs0%,压低组死亡率高于非压低组,组间比较差异有统计学意义。结论:APE患者心电图ST段压低发生率高,不同栓塞面积患者的ST段压低发生率和心电图表现有差异,ST段压低APE患者病情严重程度较高。

[Abstract] Objective: Analysis st-segment depression in acute pulmonary embolism patients. Methods: 128 patients with APE were selected as the research object, grouped according to st-segment depression . Results: 72 cases of patients with st-segment depression, the occurrence rate was 56.25%, the middle area group of AVF, V2 and V6 Leads st-segment depression occurrence rate is higher than the small area group (P < 0.05), the largest area group III, AVL, AVF, v1, V6 st-segment depression occurrence rate is higher than the small area group (P < 0.05), the largest area group III, AVL, lead V1 and V2 of st-segment depression occurrence rate is higher than that of the middle group (P < 0.05). The incidence of shock was 4.05%vs3.7% ,the mortality was 8.11%vs0%, the mortality of the depression group was higher...
