Electronic Monitoring verses Manual Monitoring heart rates

[1peaches77]

Every single electronic monitor  I have used reads my heart rate tachy.  My resting rate according to the monitors that have a chest strap and then a wrist band, always runs between 120 - 160.  When checking my pulse ( the same time as wearing the electric monitor) manually my resting rate is normaly in the 80's.  While performing my cardio work out I continue to access myself.  I have 0/10 pain, no shortness of breath ( I can talk in full sentences), no vertigo (dizziness), nothing.  Yet, my monitor will show my heart rate as high as 196.  I am a 35 year old female that weighs 180 pounds and I am 69 inches tall.  My blood pressure remains low.  My thyroid comes back fine, my 12-ECG shows Normal Sinus Rhythm.  I have no explanation as to why electronic heart rate monitors alway read me high.  I have used the wrist watch, the chest band with the wrist watch, the finger device (pulse ox machines), automatic blood pressure cuff machines that reads your pulse and defibulators.  All show tachy or very close to tachy.  The most accurate ones so far have been the defibulators and the blood pressure cuff machines.  Any suggestions would be helpful.  I have asked many collegues and no one can give me a scientific answer.

I have since made an appiontment with a cardiologist about my heart rate.  I'm curious to find out what is going on.  Thanks to all who have tried to help me.  Your kindness is truelly appreciated.

I have had the chest band-wrist monitor show my heart rate to be extremely high when it wasn't.  The cardiologist told me to get rid of it.  My bp machine does not always show an accurate reading for heart rate, but it is better than the chest-band monitor.  I most always recheck my pulse manually, frequently I am taking my bp & hr to make sure they're not too low to take my next dose of beta blocker.  I think manual is best, in particular if there is any question.  Hope this is of some  help.  Good luck.

It could be that when you are on these monitors, you are subconsciously nervous, thus, causing the raise in heart rhythm, I really cannot think of any other reason. Have you asked your cardiologist why this is?
