1. The effects of a high concentration of CO2 (PCO2 = 250 mmHg and PO2 = 360 mmHg in water) and MS222 (tricaine methanesulfonate, 1/8000 or 1/5000) on the electrocardiogram (ECG) in carp were examined using five kinds of bipolar leads from the body surface. 2. In the carp anesthetized with the high concentration of CO2 for 30 min, the QRS duration, PQ interval and and direction of the QRS axis on the frontal plane significantly changed. Even after recovery from anesthesia, delay in the QRS… CONTINUE READING
