Dizziness in a patient with a right atrial mass

摘要

A 63-YEAR-OLD, 93-kg, 170-cm man with an extensive history of cardiovascular disease presented to the cardiology clinic in the authors' institution complaining of "feeling lightheaded and dizzy." The patient stated that his symptoms initially began 3 months before this admission. His dizziness occurred as often as once per minute, was often accompanied by dyspnea, and caused him to awaken several times per night. The patient further reported that he could feel his heart "pause." He denied syncope, chest pain, and other constitutional complaints including fever, night sweats, and weight loss. The past medical history was notable for coronary artery and peripheral vascular disease.
