Podcast #197: Ashman Phenomenon

Author: Dylan Luyten M.D.

Educational Pearls:

  • Ashman's Phenomenon occurs in the setting atrial fibrillation and mimics ventricular tachycardia, but is harmless.
  • On ECG, the pattern of Ashman Phenomenon is a long cycle, followed a short cycle, followed by a complex wide complex beat.
  • The wide complex beats have right BBB morphology. The long R-R followed by a short R-R leads to conduction down the left bundle branch while the right bundle branch is still in a refractory period.
