- W2353949512 abstract "Objective To evaluate the prognostic significance of Heart Rate Turbulence(HRT) in chronic heart failure(CHF) patients. Methods 41 CHF patients and 20 patients without obvious heart diseases(control) waere measured using digitized 24h-Holter ECG recordings.LVEF、LVDD、HRT、HRV、QTd were compared in order to evaluate predictive values of HRT in CHF. Results The value of the HRT onset in patients with CHF death was significantly higher than that in control patients(-0.02±1.15,-1.24±2.0;P0.05).The value of the HRT slope was significantly lower in CHF death than in control(1.22±0.92,3.81±1.62;P0.05).The HRT slope and onset in CHF patients with VT were nearly identical to those without VT.As to the correlations between HRT,LVEF,and HRV in the CHF patients,the HRT slope was significantly correlated with the LVEF(P0.05),SDNN(P0.01),and HF(P0.01).Single Cox-regression analysis revealed that TO and TS,LVEF,TS,TO were the statistically significant predictors of CHF death(P0.05).Multivariate Cox-regression analysis revealed that TO and TS was a stronger predictors of CHF death than others(P0.01). Conclusion The HRT slope appears to be a powerful prognostic marker of CHF death and CHF hospitalization.As prognostic markers,TO and TS are stronger predictors of CHF than LVEF.However,it has limited value for predicting fatal ventricular arrhythmias." @default.
