A 61-year-old man is hospitalized after receiving an implantable cardiac defibrillator (ICD). The patient has a long history of coronary disease and sustained an anterior wall myocardial infarction 3 years ago. Two weeks ago, he had an episode of pulseless ventricular tachycardia and was successfully resuscitated. This episode led to the ICD placement. In addition to the ICD, the cardiologist also plans to initiate antiarrhythmic therapy with amiodarone. Which of the following is the most important side effect of this therapy?
(A) Hypotension
(B) Pulmonary fibrosis
(C) Prolongation of the QT interval
(D) Recurrent ventricular arrhythmia
(E) Skin discoloration
