After multivariable adjustment, consumption of tuna or other broiled/baked fish was associated with specific HRV components, including indices suggesting greater vagal predominance and moderated baroreceptor responses (eg, higher root mean square successive differences of normal-to-normal intervals [P=0.001]; higher normalized high-frequency power [P=0.008]; and lower low-frequency/high-frequency ratio [P=0.03]) and less erratic sinoatrial node firing (eg, lower Poincaré ratio [P=0.02] and higher short-term fractal scaling exponent [P=0.005]) but not measures of circadian fluctuations (eg, 24-hour standard deviation of normal-to-normal intervals).

经过多因素校正，鲔鱼或其他烤鱼的摄入与HRV某些特异性指标相关，包括了反映更强的迷走神经张力的指数和适当的压力感受器影响如更高的正常-正常均方根连续差[P=0.001；更大的正常化高频功率[P=0.008]；更小的低频/高频功率比［P=0.03］以及更少的窦房结电冲动游走（如，更低的Poincaré比［P=0.02］和更高的短期分形定标指数［P=0.005］），但不测量昼夜波动（如24小时正常-正常间期的标准差）。
