Radiofrequency catheter ablation of atrial tachycardia due to myocarditis six months after a viper bite

The present report describes a 20-year old man who developed an incessant atrial tachycardia several days after snakebite. Antiarrhythmic treatment was ineffective and six months later radiofrequency ablation of atrial tachycardia was successfully performed. A chronic arrythmia was considered as manifestation of toxic-allergic myocarditis. The possible mechanisms leading to myocarditis are discussed.
