We're doing anecdotes here, so... I think the post-COVID symptoms made me aware of parts of my body I had never had to 'deal with' or pay serious attention (I'm not into sports...). Feeling your heart doing weird stuff in normal conditions, isn't surprising to trigger anxiety and panic. The first time I felt like keeling over after some mild-the-month-before bicycle effort, I fell not only the heart symptoms but sudden fear and anxiety that compounded the situation. I called 911 a week later because I felt very strong and unusual heart symptoms, feeling like a heart attack. Nothing on either ecg, doppler, blood analysis, heart mri, effort test, absolutely nothing - the EMT said at first 'so many calls these days, most looking like panic attacks, poor people suffering with no physical traces of a problem'. ER doc was 'we didn't find anything but don't hesitate next time, it wasn't nothing and even if it's "just" a panic attack we can help'. The problem went away after 6 months of doing frequent/daily light cardio activity...
