[Closed] Weird heart rate readings - what can I do?

Went out on the road bike today and used my HRM for the first time in a long time. About 10 miles in to the ride (with lots of climbing already done) I get to a hard climb that I know I don’t like, but only because I blow up on it. (Norwood Edge)

So today I approached it slower than usual. It ramps up to 16% from flat almost instantly but I noticed even after 4 or 5 pedals strokes I had gone from 135bmp to 174 (pretty much my absolute max) and that’s not going hard or using a big gear etc.

Normally I would have to stop about 100yds further up the climb and catch my breath back before continuing. With the HRM on I just slowed until my heart reached a more manageable level. I then continued the climb

It just appeared odd to me how my heart went from nothing to max in seconds. Can it be psychological ?

I get exactly the same feeling when I start a ride/run with other people where as if I’m by myself I never feel this way. ie completely out of it , to the point of feeling like I need to stop. Half considering taking the HRM running too !

Just interested in people thoughts. Is it psychologically induced or can going on to a very steep climb ramp your heart rate up that quickly ?

Tried changing the battery in the chest strap? Last time I was getting odd readings it was the battery.

Faulty HRM

As downhillfast says sounds a bit like a battery problem or some random other crap (even with a good battery I find every now and again it can go batshit occasionally).
If you were at max you should be feeling it. Check your heart rate manually or with a phone app to compare it.

But then he'd have had to stop 100 yards up the trail to get his breath back 🙂

Sounds like artefact to me - check your strap and maybe new battery, maybe use some electrode gel to get a good signal (I'm told flappy or rubbing shirt can cause spurious readings if the actual signal's weak)

If it happens again, get off and take your pulse - see if that matches (USUALLY it should unless your heart's absolutely bombing along so that it fires the odd "blank" that you can't feel)

isn't your wife medical? (I'm not 🙂 )

I don’t think it’s the HRM. I use it on the turbo and no spikes etc ....

I've only ever had it outside (and have had it several times, usually at the start of a ride when I've not produced any sweat and at least once WELL above what my heart's actually capable of). These days I put a dab of electrode gel on the contact bits of the strap afer a tip on here)
