Figure 1: Heart hypertrophy and ventricular repolarization in control and diabetic rats treated with vehicle or carqueja essential oil. (a) Representative traces of electrocardiographic recorded in awake rats treated with vehicle or carqueja essential oil. (b) Cardiac hypertrophy index (HW/BW), the division of the heart weight value (mg) by body weight (g), HW/BW. (c) QT interval duration, in milliseconds. (d) corrected QT interval duration (millisecond), corrected by Bazett's formula: corrected QT = QT/RR. The four experimental groups: CoV (n = 5 animals), CoCar (n = 4 animals), DMV (n = 4 animals) and DMCar (n = 5 animals). **P < 0.01 versus CoV; ***P < 0.001 versus CoV; ****P < 0.0001 versus CoV;##P < 0.01 versus CoCar;###P < 0.001 versus CoCar. The parameters were evaluated with one-way ANOVA and Newman–Keuls posttest
