I can see how that would happen. I tend to forget to chart things and think, "Oh, what's been happening the past couple days?" I figure if I can't remember it, it must not have been too exciting. I've glanced at some other trackers and they're quite complex with severity and frequency and minute by minute accounts. I didn't do that with heart monitors (yeah, I'm a bad girl) and I'm not going to do it with the tracker. Just keeping the basics for my concerned doctor.
I was using it privately at one time; but, due to alot of what your explaining on top of other things, I decided to stop using it and delete it. In my case, it seemed to play a part in keeping my mind on symptoms all the more...in order to document the episodes.
I thought I'd use it for fun. I keep mine private though and I don't record every heart hiccup or moment of dizziness. I just track the really annoying stuff in case I have to face my doctor. That's always the first thing she asks me: how is your heart? Blecchh. If I didn't write something down, I wouldn't remember it at all. Well, I remember one very bad day a few days before my Dad died, felt like I was having a heart attack. But I'm still alive so I guess it's OK. :-)
I don't use the stuff on this site - I keep my own spreadsheet. Cardiac nerd, I guess.
