Humph, I’m just getting back into things after a horrid cold a few weeks ago. This morning I feel a VERY slightly tight chest in a way that I normally associate with an oncoming cold. My HRV and my resting HR seems slightly up so that might also indicate a nascent infection.
I’m pretty sure it has happened before, but so rarely I don’t remember any details; the “thumping sensation” was definitely familiar though. I’ve been using an hrm for sports for 15+ years and have probably got 6years data on TP so there is a good chance I may have recorded other instances without thinking about it. Is there any way to filter TP workouts by hrmax (e.g. find workouts where hrmax >190) so that I can go through and see if any other workouts look like genuine spikes?
Definitely go see a doctor, it’s not easy for them to find anything of any issue, especially if it only happens during hard exercise.
I had this happen a couple of times, settling down by itself after a few minutes back to normal, for it to not happen again in the ride. Ruled out faulty HR monitor.
Took Prints of the workouts and HR to the GP who was impressed with the information and referred me for further tests.
Had a 72h ecg test, and it showed no issues, even with multiple hard rides during that time, and told to come back if it happened again.
As it happens, my neighbour is a cardiac specialist and advised that it’s probably SVT (supraventricular tachycardia), and I’ve likely had it for ages, just more visible with HR monitor wearing.
Potentially fixed by catheter ablation, but if it’s not causing me to feel ill, light headed, fainting etc, probably best to leave alone.
It only appears when I’m feeling run down, fighting a bug, or about to come down with a sickness. Happened a couple of weeks ago on a ride with a sharp climb, stopped at the top for 5 minutes for it to settle down and then didn’t show up for the rest of the ride. Day after was struck down with a horrible cold for 2 weeks.
Obviously different for everyone, but has it happened before to your knowledge?
Definitely go see a doctor.
