Flecainide is a Class Ic antidysrhythmic drug that can cause dangerous heart rhythm issues, leading to prolonged PR, QRS, and QTc intervals on an ECG, particularly in overdose cases.
Treatment for flecainide overdose primarily involves fluid resuscitation and administering magnesium and sodium bicarbonate.
This report presents a case where intravenous fat emulsion (IFE) therapy successfully treated a patient experiencing severe hemodynamic issues due to flecainide overdose, suggesting IFE as a potential new treatment option.
