Abstract:
The effects of dichlorotetrafluoroethane, Arcton 114, on the heart of rats were examined in 17 white rats. The animals inhaled dichlorotetrafluoroethane for 1 or 1.5 min. Severe electrocardiographic changes including marked bardycardia, atrioventricular heart block of the second degree and complete heart block were registered. Cardiac standstill appearing 11 to 31 min after inhalation was a death cause in all rats. These results are similar to our previous results concerning the effects of dichlorodifluoromethane (Arcton 12) on the heart of rats.
