Was this a hot flash or a heart palpitation/afib? Need some advice!

I was extremely exhausted spending 14 hour days working on setting up and growing my new online business. SO this morning, I had to go to Best buy.

We had to wait in line as they were only allowing a limited number of people in, at a time. I was first in the shade and then as the line became smaller, I was in the sun on this part of the sidewalk closest to the entrance. I started getting very hot and bothered by the heat, I started to get a queezy feeling in my stomach, then I started to feel like light headed, and my heart started racing at the same rate, not like irregularly. I then went back to the shaded area and breathed and I was okay. Funny I felt even better after this than I did when I first arrived at best buy.

I don't do well with heat or humidy esp when i'm dehyrdated or underslept. So was this a hot flash, a panic attack or Afib and a heart problem. I think it's the former not the latter but just checking. Thanks.

On a hot day, your cardiovascular system ramps up its efforts to radiate heat to cool you down. Your heart beats faster and pumps harder, and may circulate two to four times as much blood each minute as it does on a cool day. When temperatures soar, perspiring can put a strain on your cardiovascular system, too.

I get that sometimes in the heat. Especially when I am dehydrated and no food in my stomach. Standing in one spot for awhile and having your knees locked can make people pass out. That is what is sounds like to me and standing in heat just makes it worse.
