Abstract 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.
