Sustained ventricular tachycardia in cardiac hemochromatosis treated with amiodarone.

Cardiac hemochromatosis can cause heart failure and cardiac arrhythmias. Among these arrhythmias, ventricular tachycardia may be resistant to treatment. A case of cardiac hemochromatosis complicated with ventricular tachycardia that did not respond to intravenous lidocaine, procainamide or propafenone, nor to DC cardioversion, was successfully treated with amiodarone. Amiodarone, a class III antiarrhythmic drug, may be highly effective in similar cases.
