RESUMEN
The present study was conducted in 80 cases of snake bite to understand their possible, biochemical and electrical cardio toxic effects. All patients were subjected to routine and specific investigation (ECG, X Ray, SGOT, CPK, CPK - MB, Troponin levels). Subjects were included in three groups, haemotoxic, neurotoxic and non - envenomed group. They were subjected to investigations at the time of admission, 24 hours and 72 hours after the admission. No significant statistical change occurred in cardiac enzymes in all groups at the time of admission. Significant statistical change occurred in LDH, CPK-MB at 24 hours and 72 hours after admission in haemotoxic group. Significant statistical change occurred in Troponin levels and CPK and SGOT at 24 hours after admission but no statistical change occurred at 72 hours after admission. But there was no statistical significant change in biochemical parameters in a neurotoxic group. At admission, there was tachycardia in 29 cases (53.7%) in haemotoxic group and in 16 cases (29.7%) at 24 hours which was statistically significant. At admission there was bradycardia in 10 cases (18.5%). In neurotoxic group there was tachycardia in 6 (60%) cases at admission and in 2 cases (20%) at 24 hours. There was bradycardia in 1 case in neurotoxic group. No significant change occurred in all groups at 72 hours. The present study showed significant statistical ECG changes at admission in the non - envenomated, neurotoxic and hemotoxic groups in the form of tachycardia or bradycardia. Also significant statistical ECG changes in the form of tachycardia was observed 24 hours after admission in hemotoxic group. It could be concluded that snake bites especially haemotoxic group carry the risk of inducing cardio toxic effects but these effects are not fatal.
