Let's see if I have this right. This is my first time wearing a monitor for 30 days. I tried a 24 hour monitor, but of course nothing happened during that time. My pounding, racing and fluttering symptons became worse since the 24 hour monitor. I do have vasular disease. Hope something comes out of this 30 day one. Anyway, the monitor sometimes gets this little alarm looking token popping up and looks like it's sending signals. Does this mean that something was out of the ordinary? Sometimes its several in one day. Other days nothing. Also there is no light on my screen. It's hard to see anything. Is this the way they are made?
