To study the prognostic value of heart rate (HR) variability in heart failure, risk assessment of clinical and HR variability parameters was performed in 159 patients with stable chronic heart failure. Besides low left ventricular ejection fraction, HR variability parameters reflecting impaired vagal tone (SDNN, pNN50) were found to predict an increased risk of cardiac death and death due to progressive pump failure.
为研究心率（HR）变异性在心力衰竭中的预后价值，对159例稳定的慢性心力衰竭患者进行了临床和HR变异性参数的风险评估。除了左心室射血分数降低外，反映迷走神经张力受损的HR变异性参数（SDNN、pNN50）被发现可预测心脏性死亡和因进行性泵衰竭导致死亡的风险增加。
