A few times in the past several months (and again just a fe whours ago), I experienced what I think may be Afib. I am genrally not doing anything in particular when these episodes occur. I will try to describe as best that I can.
My heart feels like it is beating rapidly, hard and just flopping around. It doesn't feel like the normal pause then thud of a PVC. It feels out of rhythm for about 10-15 seconds and then is normal again. During the attack, I feel very weak, lightheaded and out of breath. I feel the urge to squat down when this happens which causes the feeling to terminate.
Could these be episodes of Afib? I have had numerous EKGs and two holters. The only finding have been infrequent PVCs and PACs. I think I have these episodes too infrequently for any monitor to catch.
I started taking Toprol XL last week. Do beta blockers help Afib? I am hoping once enough of the beta blocker is in my system, it will help stop these attacks. They feel so much worse than the worst PVCs feel and I never thought I would experience anything that felt worse than those things.
