Specifications
Application
The logger is ideal for a variety of studies including those looking at behaviour and stress response, in the fields of laboratory animal research, wildlife research, animal welfare and fish physiology.
Leadless ECG Derived Heart Rate
The heart rate is derived from a leadless single channel ECG. As the electrodes are part of the housing the logger is especially easy to implant. The logger takes a burst measurement of ECG at the set time interval and calculates the mean heart rate for each recording. For validation purposes, individual ECG bursts can be saved. In addition each burst is graded with a QI (quality index).
Stress-Free Long-Term Studies
The logger is especially useful when a comprehensive data set throughout the research is needed with no disturbance to the animal. The heart rate logger has a battery life of 19 months, with sampling interval of 10 min at 600 Hz.
