Figure 1. Basal evaluation of myocardial function in papillary muscles from control (n=11) and obese (n=11) rats. A, DT: maximum developed tension; B, RT: resting tension; C, +dT/dt: peak of positive tension derivatives; D, –dT/dt: peak of negative tension derivatives. Data are reported as means±SD. Student's t-test for independent samples was used to compare data.
