Heart Rate Increases (30M)
Toward the end of November I had a bout of gastroenteritis. Then had a cold about a week later. It wasn’t covid according to 2 rapid tests. I felt pretty much back to normal after that for a week or so and then I noticed my resting heart rate was higher and my heart rate is about 15-20 beats higher across the board (walking, exercising, etc). It’s been like that now for 3 weeks with no improvement. I have taken 12 days off exercising and that didn’t help either. I am a pretty fit individual and do a lot of endurance cycling. To give you an idea, before this I was riding 9hrs a week and I did 8000mi on the bike in 2022. My resting heart rate is typically 48-53bpm. No history of high blood pressure.
I saw my primary care doctor and he did an ekg, electrolyte panel, thyroid, blood count and echocardiogram. All of which were normal.
Sometimes I feel minor short bursts of pain on the left side of my chest but they are mild at best and don’t last for more than a few seconds.
I was referred to a cardiologist but haven’t gotten in yet.
I’m looking for some wisdom here if anyone has an idea what this could be and how to recover from it so I can get back to normal. Thanks!
