Abstract
Data on the effects of certain animal venoms on the ECG in in men and experimental animals are presented. The Latrodectus bites in humans caused sinus bradycardia, high P waves in II and III leads, flattened T-waves, and a prolonged QTc-interval. In guinea pigs Wenckebach's phenomenon was observed. Negative T-waves including atrioventricular block I degree were also seen after envenomation of guinea pigs with the venoms of the spiders Steatoda paykulliana and Pterinochilus sp. In guinea pigs injected with the venom of the scorpion Mesobuthus gibbosus sinus bradycardia, Wenckebach's phenomenon, elevated ST-intervals and atrioventricular dissociation were seen. Following stings of Hymenoptera in humans, a wandering pacemaker, negative T-waves and slow ventricular tachycardia were observed. Weeverfish and sconpionfish stings in some patients resulted in an atrioventricular block I degree. After the injuries by the sea anemone Anemonia sulcata, the jelly-fish Pelagia noctiluca, Seolopendra cingulata, Tabanids and Vipera ammodytes no significant ECG changes were registered.
