Abstract:
Objective:To investigate the correlation between heart rate turbulence(HRT)and heart rate variability(HRV)indices,and the impact of mean R-R interval,?-blocker and other factors on HRV and HRT.Methods:76 postinfarction patients were recruited.24-hour,three-lead ambulatory electrocardiography was performed in all subjects for the analysis of HRV(including SDNN,PNN50,RMSSD,HF,LF)and HRT(including TO and TS).And the general clinical data of each case were collected.Results:TS was positively correlated with SDNN(r=0.559,P
