高血压患者的心电图可出现多种异常改变,包括:V1导联P波终末电势增加、QRS波时限延长、碎裂QRS波、QT间期延长、ST-T改变、左室高电压等.这些改变可与左室收缩及舒张功能不全、心肌缺血相关,也可以是房性心律失常或室性心律失常的预测指标,甚至可以作为心源性死亡、脑卒中的危险因素.本文将对原发性高血压患者心电图特点、发生机制及临床意义作一综述,旨在帮助临床工作者提高对高血压患者靶器官损害的预防意识,进一步减少和避免患者的靶器官损害发生,降低高血压的致残率、病死率.“,”There are many abnormal changes in electrocardiogram in hypertensive patients,including the increase of terminal potential of V1 lead P wave,prolonged QRS duration,fragmented QRS,QT interval prolongation,ST-T change,left ventricular high voltage and so on.These changes can be associated with systolic and diastolic dysfunction of left ventricular,myocardial ischemia,can also be atrial arrhythmia or ventricular arrhythmia predictors,and even can be used as cardiogenic death,stroke risk factors.This review elaborated the characteristics of electrocardiogram in patients with essential hypertension,and its mechanism and clinical significance,designed to help clinicians to improve the prevention of target organ damage in hypertensive patients,to further avoid the occurrence of target organ damage,reduce the morbidity and mortality of hypertension.
