Electrocardiograms and Echocardiography of MI Rats and Normal Rats Show the Successfully Established MI Models (Sensitivity: 10 mm/mV; Paper Speed: 50 mm/s)

(A) Electrocardiogram of rats in the sham group indicated a rather smooth ST segment and T wave. (B) Representative M-mode images with end-diastole and end-systole indicated by arrows. (C) Measurements of FS and EF. Measurement data were expressed as mean ± SD. Statistical analysis was performed using an independent sample t test. *p < 0.05, **p < 0.01 versus the sham group. N = 20.
