Ashman phenomenon

Ashman phenomenon, also known as Ashman beats, describes a particular type of wide QRS complex, often seen isolated that is typically seen in atrial fibrillation. It is more often misinterpreted as a premature ventricular complex.

It is named for Dr. Richard Ashman (of New Orleans) (1890 –1969), after first being described by Gouaux and Ashman in 1947.
