thanks...interesting thought...although my oximeter indicates a pulse rate of 35bpm when I feel the palpitations..sent doc the kardia ekg, and he says they are pacs....so perhaps, a different arrhythmia after the ablation either from the heart healing or maybe the medication(I started flecainaid and metropol after the AFib episode 2 weeks ago...he wanted me to take it for next 30-60 days...but for sure the palpitations are not phantom...I am in very good shape, no co-morbidies, work out 3 -4 times per week .... never out of breath even when I had the AFib episodes... ..but I guess only 4 weeks since ablation, so maybe need some more time....very frustrating!
