Abstract
Sarcoidosis is a multisystem disorder of unknown etiology commonly associated with hilar lymphadenopathy and granulomas. Cardiac involvement is less common; however, sarcoidosis is a known cause of restrictive cardiomyopathy. It typically presents as new-onset arrhythmias or heart failure, although cases of sudden cardiac death have been reported. We present a case of a 56-year-old male with a known history of pulmonary sarcoidosis, not on active treatment, who presented to the emergency department with a week of continuous hiccups every few seconds associated with non-exertional dyspnea. An initial computed tomography (CT) scan of the chest showed multiple stellate-like ground-glass opacities and the progression of bronchiectasis. Troponins were negative. On the initial electrocardiogram (EKG), he was found to be in atrial flutter and was admitted to the medical floor. Cardiology was consulted for suspected cardiac sarcoidosis, and they recommended transfer to the tertiary care center for further evaluation. Upon arrival, the patient underwent catheter ablation for atrial flutter and returned to sinus rhythm after the procedure. The initial nuclear scan with gallium was not suggestive of cardiac sarcoidosis. However, subsequent cardiac magnetic resonance imaging (MRI) showed cardiac involvement. Due to the high risk of arrhythmias, the patient was scheduled for implantable cardioverter defibrillator placement before discharge. The patient was given oral prednisone. The patient was discharged in stable condition, and interrogation of the device found it well functioning, and no significant arrhythmias were noted. Presentation of cardiac sarcoidosis can be variable, and any should be considered in any patient with a known history of sarcoidosis who presents with atypical symptoms above the diaphragm, such as hiccups or with new-onset arrhythmias.
