Bedside ultrasound showed no effusion and moderately decreased LV function, with B-lines of pulmonary edema. There is atrial fibrillation.

A bedside POC cardiac ultrasound was done: Findings: Decreased left ventricular systolic function. Atrial Flutter is a type of atrial tachycardia which is "Macro-reentrant," meaning that the re-entry loop is quite large, encircling much of the atrium, and you can actually see that loop on the surface 12-lead as flutter waves.
