2. Fig. 1
Electrocardiogram (ECG), trendgram of RR intervals and power spectrograms in a control Wistar rat and in an MCT-treated rat. A representative ECG record for 1.6 s in a control rat (A) and in an MCT-treated rat (B). Trendgrams of RR intervals for 300 s obtained from a control rat (C) and an MCT-treated rat (D). Short thick bars in panels C and D indicate time during ECG records (panels A and B) were obtained. Power spectra of heart rate (RR interval) fluctuations (E, F) deduced from the trendgrams in (C) and (D), respectively.

Group data of heart rate (HR) and spectral parameters in control Wistar rats and in MCT-treated rats. (A) HR; (B) Total power (TP); (C) HF power and (D) the ratio of LF to HF power (L/H): the number of experimental animals is given in parentheses. *P<0.05, ***P<0.001.

Effects of atropine on HR and power spectral parameters in control Wistar rats and in MCT-treated rats. HR (A, B) and the other parameters, TP (C, D), HF (E, F) and L/H ratio (G, H), in the control rats and in the MCT-treated rats were obtained from ECG records prior to and 30 min after the injection of atropine (2 mg/kg). The number of experimental animals is given in parentheses. *P<0.05, **P<0.01, ***P<0.001.

Effects of propranolol on HR and power spectral parameters in control Wistar rats and in MCT-treated rats. HR (A, B) and the other parameters, TP (C, D), HF (E, F) and L/H ratio (G, H), in the control rats and in the MCT-treated rats were obtained from ECG records prior to and 30 min after the injection of propranolol (4 mg/kg). The number of experimental animals is given in parentheses. *P<0.05, **P<0.01, ***P<0.001.
