Abstract

A 77-year-old male presented to the emergency department with dyspnea. A third-degree atrioventricular block was present in the electrocardiogram and an echocardiography showed a moderate mitral regurgitation with a diastolic functional insufficiency. Hemodynamic variations were assessed in the context of heart rhythm disturbances. (Level of Difficulty: Intermediate.).

Keywords: acute heart failure; atrioventricular block; diastolic mitral regurgitation.
