Figure 1

Represents the dose–response relationship in Electrocardiogram parameters following the treatment of ZnO NPs at three different doses. ZnO NPs: zinc oxide nanoparticles; ZnO NPs three doses: 25 mg/kgbw, 50 mg/kgbw, and 100 mg/kgbw. (a) HR: heart rate. (b) PR interval: conduction time. (c) R amplitude: depolarization voltage. (d) T amplitude: repolarization voltage. % Percentage of change as compared to the control group. *p < 0.05, **p < 0.001, ***p < 0.0001 compared to control group.
