I purchased a digital BP/Pulse checker. The type with a cuff for the arm, from the local Boots and it seems to be fairly accurate on pressure having checked it against the one at my GP's. However when it comes to the pulse rate I have made an assumption that 199 is the default error rate. I don't think it goes any higher. Most of the time that's the reading I get and I am pretty sure it's not correct. In fact as it's working a little heart shows each pulse and with me it misses quiet a few and then I get the 199 reading. Occasionally i do get a reading of 74 or 84 but only occasionally. Just of a matter of interest does anyone else use one of these and have similar readings?
