Case Report (n=1)
A clinical case report presenting an ECG for interpretation in a 78-year-old woman with HFrEF and an irregular heart rhythm.
Case aids ECG recognition in HFrEF; leaves open generalizability without further validation.
A 78-year-old woman presented to the emergency department with progressive dyspnea and palpitation.She had a medical history of hypertension, type 2 diabetes, right coronary artery stent, and recently diagnosed heart failure with reduced ejection fraction (30%-35%).She was treated with metoprolol, which failed to alleviate her symptoms.The initial laboratory finding was notable for 3 negative serial troponins.She was noted to have irregular heart rhythm on telemetry, for which cardiology was consulted for management of atrial fibrillation.Her admission 12-lead ECG is shown in Figure 1.How would you interpret this ECG?What is the most likely diagnosis?Please turn the page to read the diagnosis.Figure 1.Twelve-lead ECG on admission.
