Very good points made so far. I have a few questions (which you needn't answer of course):
1) Why did you think of PFO? Sometimes, when someone offers a question of self-diagnosis, especially a cardiac one, there may be a point of simmering worry about personal/family history.
I'm a bit curious about the apparent asymmetry of the event.
2) Was there any weakness in the arm?
3) How long did the episode last and did it resolve by itself?
4) Do you notice anything else strange happening? Perhaps any change of vision or balance or speech or thinking?
