老年前期、老年期室性早搏的临床意义(附244例分析)

THE CLINICAL SIGNIFICANCE OF PREMATURE VENTRICULAR CONTRACTION IN THE PREAGED AND AGED PATIENTS——Analysis on 244 cases

室性早搏(室早,即PVCS)广泛存在于人群中,尤其常见于中、老年人。随着年龄的增长其发生率也增高。本文就24小时动态心电图(Holter)观察。

By the investigation of Holters's ECGwas performed in investigating the 244 casesof premature ventricular contraction (PVC).Authors conclude: (1) Cardiovascular diseasesare the main cause of PVC in middle agedpersons. Coronary heart disease (include my-ocardial infarction) is especially susceptibleto PYCs. (2) PVCS originated from left ven-tricle are usually induced by lesions of leftventricular wall especially that of the cardio-vascular diseases. Biventricular PVCs mayoccur simultaneously. No biventricular PVC'sare observed in noncardiovascular diseases andin normal control group. (3) Because PVCsimpact on cardiac output directly.. The morePVC grade increases, the more effect of PVCon cardiac function be enhanced. If PVC isbelow grade Ⅱ the effect on cardiac functionis little. These patients whose etiology shouldbe further invodigated. Patients with gradeⅢ on the higher should pay much careful andtry to find out the cause and treat in timein order to prevent attack of sudden death.
