Effects of OA, DTX-1 and YTX on rat electrocardiogram (ECG). ECG parameters (HR, PR interval, QTc interval and T wave) were analyzed before and at different times after intravenous administration of 20 µg/kg OA to 5 rats, 16 µg/kg DTX-1 to 5 rats and 10 µg/kg YTX to 7 rats. (A) Representative ECG recording at 50 mm/s. The landmarks and the measurements of PR interval, R-R interval, QT interval and T wave duration are indicated; (B) HR; (C) PR interval; (D) QTc interval and (E) T wave were measured for all treated rats in ECG recordings at the following times: −10 (before toxin administration), 0 (toxin administration), 50, 110, 170 and 230 min. At every time point ECG was recorded for 10 min.
