Is Adenosine how heart attacks feel?

Not a typical medical question, but I've been wondering this for years. Adenosine temporarily stops your heart, right? It was an incredibly uncomfortable feeling for me when it was administered to me, and I've wondered since if it's what dying feels like, or a heart attack.

Wondering if anyone who's had this injection and a heart attack at some point could weigh in, or a medical professional.

Obviously not a dire or current issue.

If this can't be answered here, I would love to be directed somewhere I can ask!

Thanks!
