AGT and hypertensive disorder: Scorpion venoms are species-specific complex mixtures of short neurotoxic proteins.[4] Alpha-receptor stimulation by the toxin results in hypertension, tachycardia, myocardial dysfunction, pulmonary edema.[5] Raised angiotensin I levels have also been documented, which facilitates the sympathetic outflow through conversion to angiotensin II.[6] The unopposed effects of alpha-receptor stimulation lead to myocarditis.
