I have also had a poor quality of sleep since I started Bisoprolol and have started using melatonin which has helped. I have heard so many things about Ivabradine that I really want to try it, and might again ask the doctor about it at the next appointment, last time he said something about trying to get some samples. I know it is very expensive but I also found they have a program for lower income to help get the medication at a lower price.
The heart doctor has told me that the IST doesn't have to do with my nerves, but doesn't believe I have a heart defect in any way but from what I've reading people with IST normally have one or the other. At my next appointment (wow that is getting to sound old) he said we might talk about an ultrasound and if I need one. So far I think he believes that I am just extra sensitive in that part of the heart.
I do have a blood pressure monitor but I don't use it like a should, and when I finally feel like checking it the device is in another room. I ended up buying the Kardia Mobile (early christmas gift), and I have an oximeter that shows heart rate as well, But I'm not sure how they compare with the doctor office's stuff so I'll be taking them with me at my next appointment to try to see which one is closest.
Its almost funny that you mention about the gallbladder, about a year ago they said the pain in my ribs (which turns out to be inter coastal neuralgia, fancy words for nerve damage) was my gallbladder, and I went through several tests and an ultrasound where they found a so called polyp. They wanted to remove my gallbladder but since I was sure that they pain wasn't from the gallbladder and the polyp wasn't to cancer size I waited it out. 3months later at the next scan the "polyp" was gone. Meaning it wasn't a real polyp, not really sure what it was. I do have several other digestive issues, some of them seem to be getting alittle better since I've been on the beta blocker, though I have no idea how that works. The heart doctor believes I might have colitis but my normal doctor hasn't followed through on checking with this issues.
I'm glad to have found this site and I hope for some good support, its hard to go through this stuff alone.
