Hi Leela,
I'm sorry to read that you're feeling anxious. Try not to take your pulse (I know, easier said than done!). I hve noticed lately that my heart rate has been higher even on the same dose of beta-blocker. I have also talked to people who have to change their beta-blocker dosage sometimes due to a higher or lower than normal (for them) heart rate. I know if my heart is beating like 55 and it's time for my beta-blocker, I hold off on it. Or, if my hear is beating like 110 and my regular dose hasn't helped, I'll take like 1/4 of a pill more. Remember, our heart rates aren't always the same all the time. They shouldn't be, they have to adapt to our bodies, our environment, all sorts of things. I have read about Long QT also and it scared the crap out of me for a while. I started reading the QTc on my EKG printouts and mine is scary because mine is kinda close to the borderline: my QTc is usually like 433 or 436. Some sites say it should be below 430, some say 440, most say 450 for women. I did talk to my cardiologist about it and he said that in young people, Long QT was one of the first things cardiologists looked for. Plus, the great majority of Long QT patients have relatives who have either died at an early age or who have had a cardiac arrest suddenly at a relatively early age. Many patients also experienced fainting as a child, especially after swimming or running around playing. It's a scary thing to read about, but it is RARE, and I know a cardio has checked you out, so I think you can cross this off your worry list. Don't worry about your heart rate of 56, that is totally normal, especially in a person on beta-blockers or a fit person. When I was at the peak of my running, my heart rate would barely hit 40 while I was sitting very still and quiet. I know we've talked about how beta-blockers are helpful and a hindrance to us. If you're not on a high dose, though, your heart rate is going to be controlled well. It won't get dangerously slow, so don't worry about that. Even on beta-blockers, when i wake in the morning, my heart rate is high. The medications usually don't truly last a full 24 hours (or 12 hours, whatever they're supposed to) so by the time we get up in the morning our meds have worn off, plus there's that little "adrenaline rush" of waking. I've been taking my Xanax XR in 2 doses, one in the morning and one in the late evening and it seems to help blunt that effect of the morning racing heart and shaky feeling. Take care, you are ok, you've been checked out thoroughly. Like most of us, you're just fixating on normal bodily functions. HUGS!
