A rare complication of scorpion venom: atrial fibrillation.

Although the clinical findings of scorpion stings are often mild, they may lead to multiorgan failure and even cardiogenic shock. The toxin has both local and systemic effects. Local effects include edema, bruising(ecchymosis), and burning pain,whereas systemic effects include nausea,vomiting, hypotension or hypertension, cardiovascular toxicity, renal failure,and hemorrhage at different areas. The toxins have been implicated in a number of cardiac arrhythmias, including torsade de pointes, long QT syndrome, and atrial fibrillation. Here, we present a 90-year-old woman with no history of drug use or complaints due to dysrhythmias who developed atrial fibrillation after being stung by a scorpion.
