I know high pulse rate can be a problem for many people on this forum. The worse I feel, the higher the pulse (cause or effect, who knows?). My 'bed' days can have resting pulse 100, any movement out of bed will easily send it to 130 or higher. Quite by accident, I found that taking 500mg of calcium will bring it down to the resting rate around 80 within 1/2 hour. Works every time for me. Just wondered if anyone else had noticed this? Or could explain it?
