MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
Afternoon all..
Over the past 6 month I have noticed that my HR jumps from around 185 to 219 BMP when Im really giving it some. I hung out at over 210 BMP for over 15 mins last weekend in a race ,I knew something was up but didn't have HR on my Garmin display .
I can really feel it when its happening and it like someone has switched a turbo switch in my chest .I would love to say this is a normal thing and Im just that fit but its not, my Max HR is 190 at a push.
I have tried 3 separate HR monitors and it the same story on every one.
I guess Im asking ...Should I be worried because is scares the shit out of me when ever it happens ?
Perhaps you are wrong about the latter point? What makes you think your max HR is 190?Baggy - Member
I hung out at over 210 BMP for over 15 mins last weekend in a racemy Max HR is 190 at a push.
The other possibility is that the heart rate sensor is misreading. They're particularly susceptible to picking up spikes from an electric fence, which pulse at about 25 bpm. Add this to a more realistic max of 185-195 and you've got your phantom 219 bpm.
I'd also caution that 219 is about as high as these devices will measure anyway, so you're likely seeing an artificial cap on the reading.
Does it happen in the gym / on a turbo? Hop on a rowing machine and go flat out for 2k, which will give you a good baseline for your max.
The Garmin straps are prone to missreading due to jersey flap.
My Polar used to spike at about 230 quite regularly on certain rides (same spot every time), whereas my max is about 203 these days.

EDIT: I once left it recording whilst I drove home (not wearing the chest strap), got all sorts of weird readings off the car electrics...
It'll be a mis-read caused by interference from something. Overhead pylons, electric fence, sometimes even iron railings.
My old Polar used to spike at 230 at one particular point on a descent and a wireless cycle computer I had on an MTB many years ago went all haywire when my lights were mounted next to it - the power through the light cable running next to the computer set up all kinds of weird readings.
HR monitors are succeptible to misreads.
However, given that you say you have tried 3 different monitors and are aware of it happening even when not wearing a monitor, I would advise a trip to see your GP.
As far as I am aware excercise induced tachycardias are not seen as particularly risky but, if this is happening, it should be diagnosed and prognosed by a doctor.
