[|Human|] I have been taking a generic form of Lopressor because about six months ago I had a bout of afib and went to the hospital to get checked out. My regular doc and a cardiologist attended.  The gave me echograms and ekgs and other tests and found all was well-- no damage.  They said I had the heart and lungs of a much younger man-- Im 64 and not at all overweight and I work out six days a week,but I still have what feels like an ocassional flutter or two-- no pain or tightness or anything else.My question: does this ocassional flutter have anything to with the beta blocker? Anxiety?
[|AI|]  Hello, Beta blockers doesn't cause flutter, but there are given in patients with flutter. Because flutters causes heart to beat at very fast rate which may decrease the blood pressure. So protect from this happening, beta blockers are given. Anxiety may be a precipitating cause sometimes but It's not exactly the cause for it. Hope I have answered your query. Let me know if I can assist you further.
