I finished week 6 yesterday and, at 67 and never having run before, I am very pleased. Up to yesterday my highest heart beat registered on my Fitbit was 155 but yesterday there was a 2 minute spike of 186. Alarming! It cones down readily when I finish and my resting HB is 55.

Can't comment on your heart rate, I don't monitor mine, but very well done for completing week 6. I've just got in from doing run 1 of week 6. Maybe I should monitor my heart rate? I'll be 60 in February.

I wouldn’t over worry about this... wrist based heat rate monitors are notoriously susceptible to picking up on cadence and are also not 100% accurate to start with. If you felt ok, then you probably weren’t anywhere near in trouble... usually you’d experience other issues that you’d feel before getting to your true maximum HR. If you’re concerned, speak to your GP for advice and as things (within the NHS at least) are getting back to normality you may be able to go for a test if deemed necessary by them.
Great job with the running... you got this, enjoy closing it out.

As UnfitNoMore says, it probably reverted to detecting your foot cadence instead of your heart rate for a moment. It will be more obvious by looking at the HR plot ... if you see the spike is very sudden, you can be sure it's a false reading. Hearts are not made of metal, to be switched on/off in an instant... any changes happen relatively gradually.

Well done.
If you feel fine then you probably are, but if you feel dizzy, faint or sick then get checked out.
Many HRMs can be inaccurate.
