HRM-Pro Plus no Respiration Rate, pulse at least 20-30 beats higher

After the running activity I found that there was no Respiration Rate recorded, the pulse was at least 20-30 higher than normal. When I went uphill, the pulse rate dropped, but when I ran downhill, the pulse rate increased. I felt good the whole time. Absolutely ridiculous. My pulse is 99% between 120 and 140 when the heart rate monitor is working fine. The battery is new and the watch is an Enduro 2. I wonder why this is happening? I wouldn't write here but it happens to me very often. A colleague who has had an HRM-Tri (+Fenix 6x) for a few years has no problems.

  • damn that sucks with h10 gets same thing.  I wonder if this is a bug with ANT+ or watch firmware ??  because it is not normal with two straps and still have same issue.
    on my end I used two HRM PRO PLUS with same gaps and phantom spikes ( this only started to happen in recent month) thank you for the update and saved me the hassle to buy , test and return H10. 

    I did a base run last night with BT and I still had weird heart rate spike up of 10 beats or so for no reason. Ran top naked so can not even be static !  same pace and had a 245 on right wrist  with perfect OHR reading as reference, kinda sad I have to use OHR to reference my HRM pro plus!  the spikes of course ruined my execution score by few points.  Thanks HRM PRO PLUS on the phantom spikes!

    although not really necessary anymore, I did miss seeing the LR balance ratio in real time( this has helped me a lot over time. and improved my running form)

    The respiration data actually just dropped out one time in begining, which I am bit stunned.  I will see how today's threshold run session BT mode again  with the respiration data.

    really miss having LTHR updates tho.  stopped getting it since feb this year.   I have improve a lot since the threshold pace since Feb. ( I have even factory resetted watch in June)

    here the chart, 3 weird +10 spikes that lasted maybe 10 secs. ( strap soaked with perfect contacts) and one missing gap in respiration

  • strange, today I did a threshold run workout session.  entire respiration data chart is missing!  wonder if garmin server problem? I also noticed my training effect 2 circles are now 2 bars instead.  are you getting respiration chart ? ( if did a workout today

  • I ran today, but I didn't have my chest monitor with me to take my pulse, and I turned my wrist monitor off just before the start. I had given up on taking my pulse.

  • ah ok,  I cant do that.  doing marathon training and really need to know my heart rate in the various workouts I do

  • HRM Pro Plus and Fenix 6 X Pro.

    My last runs are like that. I went to two cardiologists because I thought that something is wrong with my heart but I am healthy of course. I have the strap 6 months. I had also hrm pro which I sent it back because the electrodes were complete damaged with high heart rate readings after few months. I really can't understand what is going on. Every run is faulty now. It disconects for some seconds and then I have high heart rates 230bpm (respiration rate is not recording).Also sometimes before it goes up it goes low bpm.

    Do you have any updates from your issue?

  • Nope no updates. Just mass random disconnects(lots missing respiration rate and weird spike or lags during it ) Garmin support says random drop in respiration is normal ...due to heartbeats changing n stuff..

    So Instead using my hrm pro plus on every run, I am forced to just use it for intervals sessions. (And pray the disconnect is not too crazy)

    My base runs and tempo I just use wrist heart rate monitor now.(epix and 245) they actually do better job than using hrm pro plus (as crazy as that sounds ) no weird spikes and is solid 

    Which is a shame Pensive

  • It is a joke what they told you about crazy spikes?
