  • Look Inside

Continuous recording of the heart beats were examined in 26 patients with various lesions of the central nervous system and in eleven healthy subjects. EEG, electromyogram, ocular movements and respiration were recorded simultaneously. The correlation between the location of lesions and alterations in heart rate were specifically inves-tigated. The results obtained were as follows.

1. The changes of heart rate were classified mainly into 3 groups, such as normal type, with-out spontaneous fluctuation of heart rate and type with slow oscillation of the base line and/or dis-turbance of respiratory arrhythmia.

2. The changes of heart rate were well corre-lated with the location of lesions. Heart rate in cases with lesions of the cerebral hemisphere and the hypothalamus showed normal type. Slow os-cillations of the base line and/or disturbance of respiratory arrhythmia were observed in cases with lesions of "cérveau isolé". No spontaneous fluc-tuation of heart rate was noted in a case with lesion of "encéphale isolé".

3. It is concluded that the main factors influ-encing on heart rate might be impulses from the respiratory center to the cardioinhibitory center in the medulla. The alterations of heart rate were not directly influenced by EEG, horizontal eye movements, eye blinking, disturbance of conscious-ness and phenomenon of the increased intracranial pressure.
