  1. Systolic blood pressure (BPV) and heart rate (HRV) variabilities computed from 0.20 to 3 Hz (total power), low-frequency (LF: 0.20-0.75 Hz) and high-frequency (HF: 0.75-3 Hz) bands of control (C), diabetic (D), myocardial infarcted (MI) and diabetic myocardial infarcted (DMI) rats. Data are reported as mean ± SEM. *p ≤ 0.05 compared with C; †p ≤ 0.05 compared with MI.
