The effects of thermal acclimation at 25 or 5 degrees C on electrical activity in the heart were investigated in Pseudemys scripta, Terrapene carolina, Chrysemys picta marginata, Chrysemys picta dorsalis, Chelydra serpentina, and Sternotherus odoratus. The durations of the QRS complex and P-R, R-T and R-R intervals were found to increase with decreasing… CONTINUE READING
