Oh yeah, I’m also a Guinea Pig, actually a scientific lab rat, I mean specimen. You see, my recorder is recording every millisecond of of the day and the battery is good for 5 years. The problem is, I’m almost 79yo with an extremely weak and damaged heart. I may not live long enough to map out the short circuit but I realized something, this recorder will record every electrical pulse my SA node commands, including the very last beat of my heart as it dies. Gee, I don’t think anyone has ever had that event happen, wow, I’ll end up being a teaching tool. Just think, my heart will be dead but “The Beat Goes On!” Just had to do that if you know the oldie song!!!
