动态心电图中频发室早与血压的关系

The relativity between frequent premature ventricular contraction in ambulatory electrocardiography and blood pressure

目的分析中老年患者动态心电图中频发室早与血压变动之间的关系,为临床诊断及治疗提供可靠的依据。方法选取原发性高血压伴频发室早患者、原发性高血压无室早患者、频发室早不伴有原发性高血压且无器质性心脏病的患者各148例及148名正常人作为研究对象,所有患者均进行动态心电图和动态血压监测,并用统计学软件从多维度进行统计学分析。结果在无器质性心脏病患者组中,伴室早患者的收缩压高于无室早组;伴有室早的高血压患者频发室早的发生率较高,心电图异常也较为严重,而无室早的高血压患者中大多伴有不同程度的心律失常。结论频发室早的发生与血压的改变之间存在一定的相关性。

Objective To explore the relationship between frequent premature ventricular contraction（ FPVC） in ambulatory electrocardiography（ AECG） of middle aged and elderly patients and the changes of blood pressure,as well as to provide reliable reference for clinical diagnosis and treatment. Methods The research objects were divided into 4 groups with 148 cases each,that was,the patients with primary hypertension complicating FPVC,primary hypertension patients without PVC,FPVC patients without primary hypertension or organic heart disease and healthy people.All the enrolled cases underwent AECG and ambulatory blood pressure monitoring. Data were analyzed by statistics software from different angles. Results Among the patients without organic heart disease,the systolic pressure of patients with primary hypertension complicating FPVC was higher than that of cases without PVC. The incidence of FPVC was relatively high in hypertension patients with PVC,and their ECG abnormalities were more severe. However,most of hypertension patients without PVC were complicated with various degrees of arrhythmia. Conclusion There exists some relativity between the occurrence of FPVC and the changes of blood pressure.
