I went for a run last week intending to keep my HR low for approx 5 mins before increasing to approx 70-80% max HR, followed by a 5 min warm down
From the attached graph you can see my HR jumped up into the 150's with no change in effort before 5 mins. I didn't feel any change in myself
I carried on at a similar pace and just after 30 mins walked to finish (see blue line show pace drop off). During the walk the HR didn't come down but showed more erratic reading until all of a sudden it dropped back to the mid 90s in a similar fashion to how it spiked to the 150's at the start
Any other runners out there experience this. I'm not sure if its genuinely me or it's the Polar HR monitor not coping with my heart doing unusual things once i start running.
I think i have been in NSR since a cardioversion 12 months ago, although i do get the odd twinge that tells me that my heart isn't as it used to be
I have a doctors appt this week, so i am going to ask if i can be referred for some kind of stress tests
