Amiodarone is an antiarrhythmic medication used to treat and prevent different types of irregular heartbeats. The drug can be used to prevent ventricular tachycardia, ventricular fibrillation and wide complex tachycardia. The medicine can also be appropriate for atrial fibrillation and paroxysmal supraventricular tachycardia. It is taken orally.
In this case, Zuk’s cardiologist, Dr. David Cannom, doubled the dosage of the Amiodarone after the patient experienced breakthrough AFib. After taking the increased dosage for several months, Zuk complained of different negative side effects. This prompted a chest x-ray that showed interstitial change in the left upper lobe. Dr. Cannom recommended a follow-up visit.
