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. The ECG below shows an example of Ashman's phenomenon. Figure 4. ECG showing Ashman's phenomenon during atrial fibrillation. Figure 5. Web19 set 2024 · Ashman phenomenon is often misinterpreted as a premature ventricular contraction (PVC) because of its appearance on the EKG as a single wide QRS …

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

WebAshman beat is an aberrantly conducted supraventricular beat due to change in refractory period of conduction system according to the preceding cycle length. Ashman phenomenon can be seen in any supraventricular arrhythmia. WebFigure 1 shows a premature atrial beat causing aberrant ventricular conduction.
