WebAshman's phenomenon is a special type of aberrant ventricular conduction, in which a bundle branch block occurs as a result of an abrupt change in the length of the cardiac cycle.

WebThe key to understanding the pathophysiology of Ashman's phenomenon is the fact that refractory period of an impulse that travels in the ventricular muscle varies from beat to beat in patients with an underlying atrial fibrillation. 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 Richard Ashman (of New Orleans) (1890 –1969), after first being described by Gouaux and Ashman in 1947. static ospf 優先度 https://texasautodelivery.com
