Relationship between heart rate turbulence and heart rate variability in patients with diabetes mellitus |

Abstract Objective To investigate the association between heart rate turbulence(HRT)and heart rate variability(HRV). Methods A 24-hour ECG Holter monitoring was performed to calculate turbulence onset,turbulence slope and HRV parameters in 50 patients with diabetes and 50 controls. Results The HRT and HRV in patients were significantly lower than those in controls. There are significant correlation between turbulence onset and SDNN,SDANN,low frequency power(LF)(P <0.05). Significant correlation between turbulence slope and SDNN,RMSSD,high frequency power(HF)was observed(P<0.05). Conclusion HRT was blunted in patients with diabetes mellitus and correlate strongly with HRV.HRT should be more useful in the diagnosis of autonomic nerve function damage.
