Hi, I had an ECG holter a few months back and apparently I had an episode of Mobitz II. The note says, “08:46, epizode of Mobitz II - < 2 s”. The cardiologist said not to come back unless I'd start fainting. I didn't question her before I went on Google and saw that it was actually dangerous. Is it possible to just have it once and never again? Should I go check with a different cardiologist? I do get sharp pains in my chest (always assume it's from anxiety or something) and sometimes I get this feeling like my heart skips a beat, I feel my blood run cold, and feel a little faint. I've never fainted though, it doesn't affect me too much.
