Hi all -- My question is does onset of A Fib come before or after diastolic dysfunction? I had one bout with A Fib 2 months ago and when they did the echo they found Grade 2 diastolic dysfunction. Everything else on the echo was normal (except mild mitral valve regurgitation, mild tricuspid regurgitation, mild pulmonary hypertension, the LV was within normal limits [4.0cm], no LVOT obstruction, no systolic problems at all - hyperdynamic (what does that mean) EF of >60%). Note: I was in A Fib when this echo was taken. Could that have affected the whole echo? Could the diastolic dysfunction be a false positive? This whole experience has been very scary. I am on the same med as before - 25mg metoprolol/day and a 325 mg aspirin. They did a cath and no blockages. The cath said by EF was 60-65%. I feel like I am waiting for the next shoe to drop...another A Fib incident or something with the diastolic dysfunction. I would just like to understand the whole thing a little better. I talked with the cardiologist...was not much help..
