Certain observations in electrocardiogram and enzyme variation in dogs, following scorpion venom injection.

The effect of scorpion venom of Buthus Tamulus species on blood pressure, ECG, enzyme and electrolytes were studied in dogs. Venom was given in doses of 2 and 4 mg/kg body weight. Hypotension and tachycardia were observed with low dose and bradycardia was significant with high dose. ST segment depression, T wave changes, shortening of PR interval were the important ECG changes apart from ventricular extrasystoles. With high dose, QRS amplitude was reduced and duration prolonged. QTC interval was also significantly prolonged. Significant increase in SGOT, SGPT and LDH levels were observed but no change in serum electolytes was seen.
