ABSTRACT
Objective To explore the changes of deceleration capacity of rate (DC) and analyze its correlation with heart rate variability (HRV) and other factors in patients with coronary heart disease. Methods One hundred and twenty-nine patients with coronary heart disease (coronary heart disease group) and 109 healthy people (control group) were enrolled in this study. DC and HRV parameters were measured by using digitized 24 h Holter. The correlation between DC and HRV parameters, other factors were analyzed. Results The levels of DC, SDNN, SDANN, SDNNi, PNN50, TP, LF, HF, AC in coronary heart disease group were significantly lower than those in control group(5.64±1.67) ms vs. (6.71±1.47) ms, (106.60±20.53) ms vs. (138.82±31.22) ms, (96.94±20.06) ms vs. (127.47±31.87) ms,(28.53±14.75) ms vs. (52.24±14.65) ms, 87.72%vs. 103.86%,(1 967.10±966.16) ms2/Hz vs. (2 846.70±1 443.41) ms2/Hz,(326.43±195.35) ms2/Hz vs.(457.64±254.30) ms2/Hz, 85.88 vs. 106.39, (-6.18±2.15) ms vs. (-7.00±2.51) ms, P<0.05 or<0.01. DC was correlated with SDNNi, PNN50,TP,LF, HF, AC both in total population or in coronary heart disease group and control group by using multiple linear correlation analysis ( r=0.586, 0.356, 0.531, 0.563, 0.435,-0.433, P<0.01). After removing confounders, DC was correlated with age, SDNNi, rMSSD, PNN50 and AC (P<0.01). Conclusions DC decreases in patients with coronary heart disease and is strong correlativity with HRV parameters. DC could be used for quantitative detection of autonomic nervous function.
