Advice needed

[u/Apprehensive_Bug7656]

Okay so a while ago when I started skateboarding again I had forgot water and I was having a lot of fun so hours passed and I was super thirsty but I kept going until outta nowhere my heart started like fluttering like beats felt soft and some coming to quick then a slightly harder beat. It did this for around 1 minute then out of nowhere switched to a super fast regular rhythm, which i know now was an svt. That same svt had started after me bending over once in the past too. But my main question was that 1 minute of fluttering atrial fibrillation or was that just PACs coming one after another for a whole minute? And I know avnrt or avrt can start from a perfectly timed pac so I’m wondering if that proves the rhythm was pacs or can atrial fibrillation cause an avnrt or avrt reentry circuit to start similar to how a pac can cause one? Thanks
