Feelings of impending doom are also a symptom of adenosine injection. [1] Interestingly, caffeine is an adenosine receptor antagonist.

Had it done to me twice, 2 of the worst experiences in my life. They did the first one and did not push enough. The doc said do you want the good news or the bad news. I choose the good, apparently there is a significant portion of people who's heart does not restart after adenosine, and they have to use the paddles to get it started again. The good news was that mine restarted so it will always restart when given the medicine. The bad news was they did not push enough to stop the SVT so they had to do it again. That was bad news it's a horrible experience. All of the symptoms of a heart attack with the exception of the pain. Can't breath, tingling, darkening vision. You think you are going to die when you feel you heart stop.

I've never really considered it a feeling of doom. It only lasts a partial second or two and you don't really have time to feel anything.

I mean, it literally can take your heart going 400 beats a minute, stop it, and instantly start going 72. It feels fucking crazy but I never have time to feel "doom" specifically.

I do know that the paramedics love administering it though haha.
