A mean reduction of plasma calcium level to 51 per cent of normal infusion of 4.7 per cent Na2EDTA solution into four cows was associated with a mean reduction of 48 per cent in cardiac output. Hypocalcaemia sufficient to produce sternal recumbency in a further four cows resulted in a highly significant fall in the mean arterial blood pressure, which returned to normal immediately after treatment with an intravenous infusion of 350 ml of 32.5 per cent calcium borogluconate.
向四头奶牛静脉输注4.7%的乙二胺四乙酸二钠（Na2EDTA）溶液，使血浆钙水平平均降至正常水平的51%，同时心输出量平均降低48%。另外四头奶牛因低钙血症而出现胸骨卧位，其平均动脉血压显著下降，在用350毫升32.5%的葡萄糖酸钙静脉输注治疗后，血压立即恢复正常。
