Abstract
- Flecainide acetate is a potent class Ic anti-arrhythmic drug with a major sodium channel-blocking effect. Flecainide toxicity can cause myocardial impairment and precipitate circulatory collapse, particularly in patients with renal failure. Electrical and hemodynamic deterioration during flecainide toxicity may not respond to conventional treatments. We report the successful management of flecainide toxicity using extracorporeal membrane oxygenation (ECMO), hemoperfusion, and bicarbonate administration maintaining alkalinity.
