Pacemaker and Garmin forerunner 235

Hi there

i am new to the PM world 3 weeks now post implant. I wear a Garmin forerunner 235 and my understanding is that my PM is set at Hr 60 ( do I shouldn’t drop below) . Subsequent to my PM implant I check my average Hr resting on my Garmin and it is still reading low resting rates. Today early morning my resting low was Hr 32. I am not sure whether there is now inaccuracy with my Garmin but it works through light monitors on my wrist .... so has anyone else had this? I only have my next check up in 6 weeks .... should I be concerned? I am 44 yrs old and a runner ...still not allowed to run yet. Thank you for your help.


32 bpm is not safe.

If Garmin is correct 32 bpm is not safe. Yes there could be a loss of capture with the pacemaker go to doctor to check.


Thank you

Garmin is not 100% accurate

The Garmin wrist based HR monitors are not very accurate.  You need to be almost hairless, have very light to albino skin, and have the watch on tight enough that it leaves an impression in your skin.  If any of those are not happening the HR reading will be inaccurate.  However, when you run if you use the chest strap there is no interference and the readings are very accurate.  I changed from the Garmin Forerunner 410 to the Fenix 5 this year.  I called both Garmin and Medtronic to make sure there would be no issues.  The chest strap has been so accurate it has helped me diagnose  problems with my pacemaker.
