Garmin Epix Pro Heart Rate Measurement Issue

Chris
over 2 years ago

Hi there,

I'm writing to share an experience I recently had with my Epix Pro (Gen 2), one of Garmin's premium watches designed to deliver accurate health and fitness measurements.

Today during my run I encountered a concerning issue with the heart rate monitoring function that I'd like to bring to your attention. There was a significant discrepancy in my heart rate readings, which I believe is indicative of a problem with the heart rate monitoring feature on my device. To provide a clear picture, I've attached images of both my heart rate chart and pace chart from the run in question.

The issue manifested as follows:

  1. In the first half of my run, my heart rate readings were consistently below 130 BPM, despite putting in a full effort. My typical heart rate during this level of exertion is around 150-160 BPM.

  2. Suddenly, at a single moment, my heart rate measurement jumped to 150 BPM and remained at that level for the duration of the run.

The attached image shows that this jump in heart rate occurred while my pace remained stable. It's a small proof that there was no corresponding change in physical activity that could explain such a spike in heart rate.

I'd like to emphasize that I took special care to ensure the watch was properly positioned and that my wrist was clean before starting the run. The Garmin Epix Pro is designed to excel in providing accurate health and fitness measurements, which is why I find it unacceptable that a simple and crucial measurement like heart rate could be so far off the mark.

As a user of one of Garmin's top-tier devices, I expected reliable and precise heart rate monitoring, especially during workouts.

If any other users have encountered similar issues or have suggestions for troubleshooting, I'd greatly appreciate your insights. But mostly I'd like to hear from Garmin's support about that matter. If there is no guarantee that a watch with this price-tag can make the simplest measurement right, while being in ideal conditions (tight strap, not extreme weather etc) then what's the point of having it in the market?
I mean, there is a point, since people like me buy it, but I guess it will not continue for long if your performance remains that bad.

Cheers

    Hi , had you a chance to test latest beta firmware? I saw there are some jumps in the Sensor Hub firmware release number.

    Hi, yes, but not since 16.17/16.18 version, i'm only doing Trail Run since that and it's pretty difficult to look at this type of activity. Alos the temperature is over 12°C here at Paris since 2 weeks.

    I will provide a feedback after a "cool" run next week.

    The temperature does not have anything to do with the bug, as it happens during indoor and outdoor runs.

    Lower ambient temperatures allow for a more consistent HR measurement graph. Your body doesn't get as hot and your pulse generally stays lower and more consistent.

    It's a Garmin, request Wink

    "Hello! I'm reaching out to a couple of users directly regarding the erratic HR issue. When you are able to try another activity, can you record another activity and let me know how the data looks? To give it the best 'chance', I'm also requesting that you warm up a little to get your blood flowing first. Please also note what the temperature is outside if it's outdoor! "

    And sometimes indoor temp is cold

    "Temp ~10°c in garage, on cycle trainer."

    I’m sure it is a Garmin request but the fact they are asking something totally irrelevant makes me think they’re still at a loss with one of the most unbelievable bugs I’ve ever seen. And I have had it for 10 months already.

    Can do that - in fact asked if there is sth. I can provide a few posts back here in the thread.

    What data/format is requested - the diagrams (then see few posts back already) or the exported activity data (can provide that based on a past run as well), or ...?

    I can provide some for sure. Keep us posted in case they want additional info outside this thread

    It’s still happening to my epix on the latest beta firmware. Just did a run yesterday and it spiked from 150 to 180 and stayed there the rest of the run. Happened around mile 4 of 6.

    I had a similar problem during an elliptical workout. Epix Pro on the left wrist, AWU on the right wrist and heart rate monitor connected to the elliptical. During the first training phase the AWU and the heart rate monitor measured the same value, EPIX PRO a much higher heart rate. Halfway through the workout, the EPIX Pro was in line with the other two measurements.
