心率波动的功率谱分析提供了一种定量的非侵入性手段，评估犬短期心血管控制系统的功能。交感神经和副交感神经活动对心率功率谱做出频率特异性贡献。肾素-血管紧张素系统活性强烈地调节位于0.04H的光谱峰的幅度。在几秒到几分钟的时间尺度上，肾素-血管紧张素系统显然在短期心血管控制中起重要作用。
Power spectrum analysis of heart rate fluctuations provides a quantitative noninvasive means of assessing the functioning of the short-term cardiovascular control systems in dogs. Sympathetic and parasympathetic nervous activity make frequency-specific contributions to the heart rate power spectrum. Renin-angiotensin system activity strongly modulates the amplitude of the spectral peak located at 0.04 H. The renin-angiotensin system apparently plays a significant role in short-term cardiovascualr control on the time sclae of seconds to minutes.
