He denies URI symptoms, fevers/chills or recent sick contacts. At baseline, he is able to walk several miles without difficulty and now is limited to < 1 city block. His PMH is notable for paroxysmal atrial fibrillation for which he has been on warfarin and amiodarone for several years. He also has an AICD for his history of non-ischemic cardiomyopathy (most recent EF of 40%).
