充血性心力衰竭患者动态心电图的研究进展

Research Progress of Dynamic Electrocardiogram of Patients with Congestive Heart Failure

在充血性心力衰竭(CHF)病情进展过程中可伴发各种不同类型的心律失常,导致患者病死率增加。一直以来,CHF的早期诊断和干预均是临床改善患者预后的重难点。心脏动作电位传导延迟、心肌电生理改变、复极电流降低等是心力衰竭疾病发生、发展过程中心肌损害的主要动态心电图表现,对患者的预后有重要的警示作用。动态心电图对帮助临床更加全面了解患者心肌-心电学改变具有重要意义,对疾病的早期治疗有一定的指导价值。

The progression of congestive heart failure(CHF)may be accompanied by various types of arrhythmia,which increases the mortality of the patients.Early diagnosis and intervention of the disease have long been valued clinically,which is the key and difficult point to improve the prognosis of the patients.Cardiac action potential conduction delay,myocardial electrophysiological changes and decreased repolarization current are the main dynamic electrocardiogram manifestations of myocardial damage during the occurrence and progression of heart failure,which has an important warning effect on the patient′s prognosis.The dynamic electrocardiogram is of great significance to help the clinic more comprehensively understand the changes of the patient′s myocardium-electrocardiology,and has a certain guiding value for the early treatment.
