Cardiac monitoring

External ECG recording

The DECRO emitter is capable of recording a low noise and high resolution (24 bits) Electrocardiogram (ECG) using two electrodes placed on the left and right flanks of the animal after local clipping. The electrodes are protected by the jacket.

ECG is recorded at 500 Hz and exhibits low noise levels with QRS complexes. The software provides built-in 50 Hz noise removal filters, automatic cardiac cycle detection and heart rate calculation.

Automatic event detection:

  • R peaks automatic detection

Physiological parameters calculated:

  • R-R intervals (mS)
  • Heart Rate (BPM)

Example of ECG signal recorded on an animal at rest

An example of ECG, Cardiac Rate and activity signal

The ECG signal above is recorded during a resting phase from an adult Sprague Dawley male rat, dressed with DECRO jacket. The figure displays from top to bottom the ECG signal (lead II configuration ECG) with R-R intervals detected, instantaneous heart rate and activity level reflecting resting phase over 10 seconds.
