Abstract:
A method for 24 h recording of the heart rate (HR) in unrestrained, freely moving rats is described. Commercially available biotelemetry transmitters were used in combination with normal ranged FM-receivers. The data presented show a pronounced diurnal rhythm in the HR of the rat. When the rats are exposed to noise a large increase in the HR could be demonstrated. The system described is also suitable for analysis of the time parameters of the electro-cardiogram (ECG).
