1份心电图诊断心力衰竭的探讨及文献复习

The Discussion and Literature Review on One Copy of Electrocardiogram in the Diagnosis of Heart Failure

摘要: 目的：通过对1例明确诊断为心力衰竭患者心电图的深入分析，探讨心电图诊断心力衰竭方法的可行性。方法：收集该患者的临床资料，包括病史、临床表现、心电图、心脏超声、胸部X线等，结合心电图“掉头”现象及国内外文献，深入探讨心力衰竭心电图的特点。结果：患者心电图的基本特征为完全性左束支传导阻滞(complete left bundle branch block, CLBBB)，在病程中相继出现“掉头延迟”、“掉头迟钝”及“掉头失败”等心电特征。结论：本例心力衰竭患者的心电图表现符合心力衰竭心电图的变化特征。

Abstract: Objective: To explore the feasibility of electrocardiogram in diagnosing heart failure through in-depth analysis of electrocardiogram of one patient with definite diagnosis of heart failure. Methods: The clinical data of the patient were collected, including medical history, clinical manifestation, electrocardiogram, echocardiography, chest X-ray and so on. Combined with the “U-turn” phenomenon of electrocardiogram and the literature at home and abroad, the characteristics of heart failure electrocardiogram were discussed in depth. Results: The basic characteristics of electrocardiogram were complete left bundle branch block (CLBBB). In the course of the disease, the characteristics of “U-turn delay”, “U-turn slowness” and “U-turn failure” appeared successively. Conclusion: The electrocardiogram of this patient with heart failure is consistent with the electrocardiogram changes of heart failure.
