THE CHATTERJEE PHENOMENON: A DEMONSTRATION OF CARDIAC MEMORY IN PACED RHYTHMS.

Introduction: While T-wave inversions (TWI) are associated with various pathologies, they are rarely associated with cardiac memory, termed the Chatterjee phenomenon.

Case: A 76-year-old man with sick sinus syndrome with a pacemaker presented with chest tightness and new onset TWI in his precordial leads. On admission, he tested positive for COVID-19, but remained stable and only required minimal supplemental oxygen.

Cardiac tamponade as a complication of bronchogenic cyst.

Bronchogenic cysts are rare incidental findings, but they can have life-threatening complications. Herein, we report a case of a 44-year-old man who presented with complaints of left-sided chest pain, intermittent dyspnea, and pink-tinged sputum. Computed tomography angiography of the chest revealed a large cystic mediastinal mass in the subcarinal location.

Acute ischemic stroke as initial manifestation of undiagnosed iron deficiency anemia: case-report and literature review.

Cerebrovascular disease is the second leading cause of death in the United States in adults aged 65 years and older and is most commonly caused by atherosclerosis. More so, cryptogenic strokes account for one-third of all ischemic strokes. At the same time, iron deficiency anemia is prevalent worldwide and mostly affects females of childbearing age.

Ventricular fibrillation as an initial manifestation of cardiac sarcoidosis.

Cardiac sarcoidosis is a rare immunologically driven process seen in 2% to 5% of patients with systemic sarcoidosis. We present a 31-year-old woman who presented after a ventricular fibrillation cardiac arrest. A comprehensive diagnostic workup was unrevealing.
