Parenteral ATO prolonged QTc and APD.
(A) Acute feeding of ATO resulted in progressive dose-dependent prolongation of QTc. *P < .05 versus control; #P < .01 versus control; +P < .001 versus control. (B) Chronic feeding of ATO produced time-dependent prolongation of QTc. *P < .05 versus control; #P < .01 versus control. (C) APD of papillary muscle after eighth day chronic feeding of ATO, showing longer APD90 in ATO-treated ones. #P < .01 versus control; +P < .001 versus control.
