> my heart had an irregular beat followed by a drop in blood pressure Yes I had that happen EXACTLY. After a coffee a few years back. First I felt a little weird beat in my heart, like it skipped a beat. That sort of scared me which probably made it worse, then blood pressure dropped a ton. Almost like i might pass out. Lost fine control of my fingers as they cramped up into an eagle's claw position. Then all was well after a few minutes of controlled breathing. I strongly suspect caffeine played a role. But I only had my "normal" morning coffee, an XL cup from a gas station. Was nothing unusual for me. It's hard/impossible to confirm what my problem was. Regardless I drink decaff now and get the same enjoyment from it.
