Review Question - QID 212893

A 38-year-old woman presents to the emergency department for acute-onset chest pain. She reports that while eating breakfast this morning she experienced a 10/10 crushing chest pain that resolved within 5-10 minutes. She reports diaphoresis, dysphagia, and shortness of breath during the episode but denies fever, chills, weight changes, or nausea/vomiting. The patient admits to having 4-5 similar episodes within the past 4 months, each lasting around 5 minutes with no obvious precipitating factor. Her past medical history is unremarkable besides some residual cough from an upper respiratory infection last week. She experiences another episode at the emergency department. A bedside electrocardiogram (ECG) is obtained and shown in Figure A. Troponin is 0.03 ng/mL. Her pain resolves following nitroglycerin administration. What other finding would you expect to find in this patient?
