A 64-year-old man with a history of a dilated cardiomyopathy presents to the emergency department with worsening shortness of breath. A chest radiograph shows changes consistent with congestive heart failure. He is treated with intravenous furosemide (Lasix) and oxygen. His pulse is noted to be rapid, and a 12-lead ECG is obtained.
