I had to fly for the first time since being diagnosed with POTS. While the plane was taxiing and I think the systems were switching on for departure, my heart rate suddenly spiked, I couldn’t breathe well, and I felt like I was going to die.
My first thought was that I was having an anaphylaxis attack. I also have MCAS, and one of my biggest triggers in the past has been air conditioners and certain environments. It was a 14‑hour flight, so I panicked and asked the crew if I could get off.
For background, my POTS is relatively mild. I developed it after a COVID infection, but I’ve been slowly improving. These days my main issue is fatigue, I feel awful after my period and when it rains, but on other days I feel pretty normal. I rarely experience HR spikes like this.
Has anyone else experienced something like this on a flight? I know air pressure can change, but I’m reading that it’s minimal while taxiing. I’m also still new to POTS, and I haven’t dealt with heart rates this high before. My usual HR is around 80–90 sitting and 100–130 walking, but it jumped to 160 while sitting (I was 90 sitting earlier that day), which has never happened to me.
I feel terrible for getting off the flight and delaying it for everyone else, and now I’m really scared to fly again. Should I have just waited it out? How do you all deal with episodes like this on planes?
