Abstract

A 49 years old Nigerian female presents with breathlessness, pedal swelling, orthopnea, paroxysmal nocturnal dyspnea (PND) and palpitation. She had a goiter. Her EKG result showed atrial fibrillation. A 27 year old Nigerian female with Grave’s disease diagnosed 10 months prior to presentation presented with breathlessness, palpitation, orthopnea and PND. She was previously treated with carbimazole and propranolol with poor compliance. A 55 year old Nigerian female presented with breathlessness, orthopnea and PND. She had a history of a goiter 30 years earlier which regressed. Thyrotoxic heart disease can present with arrhythmia or dilated cardiomyopathy.
