Key result
A novel method using fast Fourier transform on single-lead ECG successfully isolated respiratory rhythms in anesthetized and awake mice, allowing simultaneous monitoring of cardiac and respiratory functions.
A novel method using fast Fourier transform on single-lead ECG allows simultaneous monitoring of respiratory and cardiac function in mice.
New method links peripheral cardiorespiratory monitoring with central neuronal recordings; leaves open autonomic interactions in cardiovascular disease.
Normal circulatory and respiratory systems are essential for animals to survive and are regulated by the autonomic nervous system, which is under the control of the central nervous system. However, it still remains unknown whether and how the peripheral systems and individual neuronal activity in the central nervous system interact with each other. To address this question, we developed a simple method that monitors both circulatory and respiratory activity, which can be easily combined with neurophysiological experiments.

Sato et al. (2018) studied this question. Simultaneous monitoring of respiratory and cardiac function using ECG and fast Fourier transform was evaluated on Isolation of respiratory signal from ECG. A novel method using fast Fourier transform on single-lead ECG successfully isolated respiratory rhythms in anesthetized and awake mice, allowing simultaneous monitoring of cardiac and respiratory functions.
