A ECG recordings of the hM4Di + Model group. B The statistical analysis of ST deviations in each group of rats. Data are expressed as the mean ± SD. ***p < 0.001, n = 6 rats/group. C The statistical analysis of LF/HF ratio in each group of rats. Data are expressed as the mean ± SD. ***p < 0.001, **p < 0.01, n = 6 rats/group. D Comparison of frequency domain analysis in each group of rats. E Comparison of left ventricular echocardiography in each group of rats. F The statistical analysis of LVEF, LVFS, LVIDs, and IVSs values in each group of rats. Data are expressed as the mean ± SD. ***p < 0.001, **p < 0.01, n = 6 rats/groupBack to article page
