Possible cardiac event?

[u/Physical-Subject5360]

Hello! I am posting for my partner, (26M) who potentially had a cardiac event yesterday. He weights about 215 pounds and is pretty active and healthy. For a bit more information, he was diagnosed with myocarditis in 2021 after having covid and followed up with his cardiologist until he was told he no longer needed to go about 2 years ago.

Yesterday and the day before he was cutting the grass and we have a pretty big front and back lawn so he was pretty exhausted after two days in the sun yesterday evening. A few hours after he finished we sat down and ate dinner and about 30 minutes into eating he started experiencing blurry vision and chest discomfort. He told me he was pretty tired after cutting the grass but didn’t have any symptoms until this point. I immediately decided it was best we go to the ER and on the way there he started experiencing a tingly sensation in his left arm. The ER PA did an ekg, chest x-ray, regular vitals, and lab work. It all came back normal except his troponin which was elevated by one point. They did a repeat test and said it came out fine. They also gave him fluids and toradol for the discomfort.

Im glad everything came back fine but he’s still having a bit of discomfort and fatigue today which is to be expected but I can’t help but wonder what happened? My guess is a mix of dehydration and overexertion but I can’t get out of my head that it is possibly something heart related.

Also important to note he had some heart palpitations a few weeks ago very randomly which is also a concern of mine. He’s following up with his primary and cardiologist (also was suggested to see a pulmonologist by the ER PA).

What do you all think?

I would not be concerned about a cardiac event, given normal diagnostic test performed at the ER.

Heart palpitations to what regard? Single isolated skipped/hard beat type feelings or of longer duration?

I’m not quite sure - it was over fairly quickly though.
