title: [Amidaron-induced dermatopathy resulting from unnecessary Cordarone therapy of ventricular parasystole].
abstract: The case history of a patient is reported who was treated with a variety of antiarrhythmics over a period of years because of refractory ventricular "bigeminy". As the arrhythmia did not respond to any kind of therapy, amiodarone treatment was started, which the patient received in a maintenance dose of 600-400 mg/day for 4 years. More recently, a bluish-grey hyperpigmentation of the face and other areas of the skin exposed to sunlight developed. A cutaneous biopsy of the hand revealed pigment deposits and lamellated lysosomal inclusions characteristic for amiodarone dermatopathy. The interactive, computer-assisted analysis of the ventricular ectopic activity has clearly demonstrated its innocent, parasystolic nature. The differentiation between ventricular extrasystolic and parasystolic activity is essential, because the latter arrhythmia does not require specific antiarrhythmic pharmacotherapy.
