Abstract
|
|
|
Experimental hypocalcemia was induced in normal goats by intravenous infusion with various concentration of Na₂-EDTA solution.
1. Progressive depression of reflexes and body temperatures paresis, and cardiac arrest were observed in two groups infused with 4% and 8% EDTA solution, whereas paresis and cardiac arrest were not observed in 3% EDTA group.
2. The patterns of electrocardiogram were changed according to the decrease of plasma Ca level in all of 7 goats. When plasma Ca decreased to 6㎎ per 100㎖ or below, sinus bradrcardia or tachycardia and prolongation of QT interval were showed, while atrioventricular block was noted in case which the plasma Ca level decreased to 4㎎ per 100m1 or below. Fibrillation and cardiac arrest were evident in case which the plasma Ca level decreased to as low as 3㎎ per 100㎖.
