Well my heart always pounds in these situations. I hate going out because of heat. Always feel like fainting. The funny thing is I had 100s of these "about to faint" situations but it never actually happened. It basically gets to ~110BPM, vision starts to get blurry, kind of white as if there was a very bright light. I just sit down an it slowly reverts back to normal. Buys me some time to get to an AC'd place lol. I kind of had it forever. Just a bit more severe in the last few years that I don't have to go out everyday, so probably heat is more of a shock. I wish it was 17C everywhere.
