Abstract：Objective To investigate the correlation between ventricular premature complexes(PVC) and mean heart rate, as well as the frequency domain characteristics of Holter monitor in nonelderly population of different genders. Methods One hundred and ten cases of non-elderly outpatient patients with PVC load of >1% were enrolled and divided into male group and female group. After the Holter examination, the average heart rate per hour of each sample and the correlation analysis of PVC were divided into fastheart rate correlated PVC (F-HR-PVC), slow heart rate correlated PVC (S-HR-PVC) and independent heart rate correlated PVC (I-HR-PVC), so as to analyze the proportion of PVC types and time domain indexes of heart rate variability(HRV) between the two groups ResultsIn the male group, the proportion of F-HR-PVC was significantly higher than that of the female group (60.0% vs.33.3%), while the proportion of I-HR-PVC and S-HR-PVC was lower than that of the female group respectively(24.0% vs.36.7%, 16.0% vs.30.0%) HRV analysis of the patients in the two groups showed that rMSSD (40.64±27.40 vs.27.83±9.31,P=0.020) and pNN50 (11.60±9.31 vs. 7.17±5.92, P=0037) in the male group were higher than that of the female group. The SDNN and SDANN showed no statistical difference between the two groups.ConclusionIn the nonelderly population without definite heart disease, the proportion of F-HR-PVC in the male group was higher than that in the female group, and the proportion of S-HR-PVC and I-HR-PVC was lower than that in the female group, suggesting that the clinical incidence of PVC in the male group may be related to the increase of sympathetic nervous tone, and the female group may be related to the sympathetic parasympathetic nervous system and estrogen.
