Well, coming to the end of Day 6... I went in last Wednesday at noon, and I came home Monday morning. It's now Tuesday night, and other than having a lot in common with kittens (strength, not mobility), I'm feeling great.
Tomorrow, I need to go for lab work in the morning, so we'll get another look at what my INR is settling out to. (it was 1.7 when I left on Monday AM). Happy coindidence; my wife went to the local small-town pharmacy to see if they had all the prescriptions I needed, and when she gave the list to the Pharmacist, he said "oh, cardiac patient, eh? What was it, a valve?"
Turns out the guy was a Cardiac Pharmacist at a major centre for 10 years, then bought this small-town Alberta drugstore so he could move his young family out of the city. He told her to have me call, anytime, if I had questions or concerns, gave her his home phone number, and helped her order a Coaguchek XS with supplies, which is what the pharmacist from the INR clinic at the U of A had recommended. (She also recommended letting THEM help me to stabilize the INR, and running tests in parallel with the lab for a while, so they could help me learn to do this on my own...)
Wow. The quality of care on this little journey has been world-class, from start to finish; I sure as hell don't want to do this again, but knowing how good the care is, I wouldn't be afraid to, either.
OH! And I finally can hear my valve!! It sounds incredibly faint, like a watch, and the sound just blends into the background, but once I figured out what to look for, it's right there! (I reorded my chest with my iPhone, and it was very clear... from that point on, I can hear it no problem.) But only in one ear... I can't hear it with my left ear (ah, approaching deafness, probably caused by the open-window effect over the last million or so miles. - for you aussies, that's the left side, in normal cars
My resting HR is 91 now - a far cry from the 58 that's been normal most of my life, but I'll take it, for now. I've got time, patience, and I'm sure it'll come along.
