I get a weird symptom on LSD lately. Occasional heart flutters / palpitations, that feeling 1 beat missing but it's just my heart beating twice suddenly instead of a single beat. It's not atrial fibrillation if I can trust my watch. For better of for worse I have a pretty accurate view of my heart health, I had palpitations for a while so I went through every test and should have a "mostly" healthy heart. The main point though besides the fluttering: my heartrate variability nosedives during a trip on LSD. My normal HRV heart rate variability is usually around 60 which is meh, but on LSD it dips into very low territory sub 20s. After trips it always balances out but I'm honestly getting annoyed and worried at heart flutters).

I'm curious if anyone else found similar symptoms of particuarly: 1: heart palpitations, 2: drastic drop in heart rate variability?
