I had an ambulance ride last night, due to a sudden heart issue.
It turned out to be a wise decision, because I had to be cardioverted electronically.
Before that, they told me they were going to inject a drug that would stop my heart, “make me feel very bad”, and would then restore it to its correct rhythm. It did everything but the latter.
Also, I was given a more defined diagnosis as to what’s wrong, and was referred to a new (and hopefully better) cardiologist.
