To evaluate if the 0.1-Hz low-frequency oscillations of R-R interval are a reflection of rhythmical pattern of discharge of the sympathetic outflow, we analysed in 10 decerebrate cats heart rate and cardiac sympathetic efferent discharge variability. A predominant low-frequency component was present in both signals, thus suggesting that the 0.1-Hz rhythm indeed reflects a rhythmical pattern of discharge of sympathetic outflow.
为评估R-R间期的0.1赫兹低频振荡是否反映了交感神经传出放电的节律模式，我们分析了10只去大脑猫的心率和心脏交感神经传出放电变异性。两个信号中均存在占主导地位的低频成分，因此表明0.1赫兹节律确实反映了交感神经传出放电的节律模式。
