The non-organic premature ventricular systole was divided into daytime group (78 cases) and night group (57 cases). daytime group: the number of non-organic premature ventricular systole in daytime accounted for more than 50% of the total number of non-organic premature ventricular systole in the whole day. nocturnal group: the number of non-organic premature ventricular systole in the whole day accounted for more than 50%. The time domain indexes of heart rate variability (HRV) were compared between daytime and nighttime groups, and their correlation was analyzed. 2.3 According to the 24-hour data of dynamic electrocardiogram, the occurrence times of pre-ventricular systole in each time period (01:00-24:00) were recorded.

The effects of pre-ventricular systole on left atrial diameter (LAD), interventricular septal thickness (IVST), left ventricular end-diastolic diameter (LVEDD), left ventricular posterior wall thickness (LVPW), left ventricular ejection fraction (LVEF) and other cardiac function indices were analyzed by SPSS 19.0 statistical software. The measurements were expressed by mean (+) standard deviation (sx (+). Results: 1 135 patients with non-organic premature ventricular systole were compared in clinical data. 1. Comparison of basic data of heart rate variability, age and sex in patients with different loads of premature ventricular systole There was no significant difference among the three groups (P 0.05), but there was significant difference in the total number of ventricular premature contractions among the three groups (P 0.01). There was no significant difference in the total number of premature ventricular contractions between the two groups (P 0.05). The clinical data of 2 103 patients with non-organic premature ventricular contractions were compared. 2.1 There was no significant difference in cardiac function between the three groups of age and sex (P 0.05), but there was no significant difference in the total number of premature ventricular contractions among the three groups of different load. There was no significant difference in age, sex and total number of non-organic premature ventricular systoles between the two groups (P 0.05). 3 135 patients with non-organic premature ventricular systoles had no significant difference (P 0.05). Comparison of heart rate variability in pre-systolic patients 3.1 Comparison of heart rate variability between different non-organic pre-ventricular systolic loads showed that there was no significant difference between the three groups (P 0.05). SDANN values gradually decreased with the increase of non-organic premature ventricular systolic load (P 0.05). There were significant differences in SDANN indexes between low and medium load (P 0.05), and between low and high load (P 0.05). SDANN values gradually decreased with the increase of non-organic premature ventricular systolic load. There was no significant difference in heart rate variability between 2-day non-organic premature ventricular systole and nocturnal non-organic premature ventricular systole (P 0.05). There was significant difference in r-MMSD between 2-day non-organic premature systole and nocturnal non-organic premature ventricular systole (P 0.05). The frequency of non-organic premature ventricular contraction with high load reached its peak at about 10:00 a.m. and its peak at about 1:00 a.m. The frequency of non-organic premature ventricular contraction with daytime predominance also reached its peak at about 10:00 a.m. and at 1:0 a.m. The number of nocturnal non-organic premature ventricular contractions peaked at about 1:00 a.m. and reached a low at about 13:00 p.m. There was no significant difference in LAD, IVST, LVEDD and LVPW between low load group and high load group (P 0.05). There was significant difference in LVEF between low load group and high load group (P 0.05). There was no significant difference in left atrial diameter (LAD), interventricular septal thickness (IVST), left ventricular end-diastolic diameter (LVEDD), left ventricular posterior wall thickness (LVPW), left ventricular ejection fraction (LVEF) between the two groups (P CONCLUSION: 1. With the increase of non-organic premature ventricular systolic load, the values of 65 Compared with patients with premature ventricular systole, the nocturnal r-MMSD index was significantly lower, mainly related to parasympathetic nerve damage; 3 Non-organic premature ventricular systole showed circadian rhythm changes. With the increase of non-organic premature ventricular systolic load, the frequency of premature ventricular systole also increased. 4 With non-organic premature ventricular systolic load. The left ventricular ejection fraction (LVEF) decreased gradually with the increase of LVE ejection fraction (LVEF).
