Fig. 4. Representative ECG recordings of the control, MNU and RFX treated animals. Recording of the heart rate variability of the individual group control (1), toxic control (MNU, 47 mg kg−1) (2), RFX (25 mg kg−1) (3) and RFX (50 mg kg−1) (4). Increased HR and decreased HRV in the animals treated with MNU (2) and the same was restored in a treatment group (3 and 4) similar to control (1).
