Looks like it settled down at the 20-25 min mark. Definite anomalies up until then. Yep dry contacts will yield radical bpms until they get wet. I always give the pads a lick before I put them on. Another reason to keep them rinsed and clean.

I suspect that the last time that I went for a ride without licking (in some form or the other) the electrodes was maybe 1995 (back in the Polar days where just getting a connection was a victory). And trust me here, in the middle of August after 15-20 minutes into a ride, I am soaking wet.

dave

ps. Here is one from late June - 1+ hours into the ride here in Southcentral NC. If better electrical contact is the problem, then some kind of medical electrode gel is the right answer. And I have no idea if this relates at all to the problem being discussed. But they certainly could be related.

Strange, have you been checked for any type of arrhythmia?

DaveLeeNC

And here is a classic. The time is misleading. This one was indoors and I first did 30 minutes at 95-100% of ftp, stopped very briefly and saved that ride, and did another 40 pretty steady at around 80% ftp. You are wet an hour+ into that kind of ride.

Dave,

Does that happened more than not on every high effort ride?

DaveLeeNC

Not that I have noticed, but it is not super common...so hard to tell. My riding tends to be relatively uniform in effort (for better or worse).

I have noticed VERY rare tachycardia events (3 times in the last 2 to 3 years). My doctor has chosen no further action at this time. I usually notice these but those symptoms are so mild I can imagine missing that during exercise.

Polar H10 is now ANT+ compatible and battery changes can be done by levering the cover open with a screwdriver.

DaveLeeNC

A bit pricey but an interesting option. Thx. dave

Laseranimal

Look at the Polar H9 then, still ANT+ compatible just doesn't give you the Duel Bluetooth Smart, the accelerometer, and the ability to store workouts without using a device that the H10 does

DaveLeeNC

Here is a high level view of the differences between an H9 and H10... https://www.polar.com/blog/polar-oh1-vs-polar-h10/ Significant (from my perspective) is that they both use no threads of any kind. You use a screwdriver to pop up a plastic cover. Also note that they do NOT use CR2032's - they use CR 2025's which might be a factor to folks (like me) who just bought a bunch of CR2032's.

And wouldn't you know it, I tried to put my Tickr on just now and one of the snaps had broken. Back to my old Garmin I guess. As long as it registers it'll be OK but I replaced it the first time because it wouldn't register for about 15-20 minutes into the ride. Outside that was OK but inside a lot of my rides were short.

I'll check with Wahoo about a replacement strap.

From sweat corrosion? You need to do a better job at rinsing that puppy! That happened to me before I started rinsing it. Wahoo replaced my strap and they should replace yours as well.
