The E/e’ ratio is a reasonable alternative, but because filling time is variable beat to beat in atrial fibrillation, there is no easy way to do an E/e’. To compensate try dividing the average of 3 E wave speeds by the average of 3 e’ speeds try to level off the variation.
Thank you for this video. Could you suggest what other methods you could use to assess LAP in a patient with AFib and short of breath?
