Yesterday I was sitting down after breakfast and suddenly out of nowhere, I had what I can only describe as 2 heart spasms (have had palpitations in the past and it wasn't like this). Within a few seconds I felt very faint and as if I was going to black out. My heart rate was about 140 an hour after, but was back to normal by the afternoon. Would you bother doing an e-consult about this? I feel fine today and am hoping it was just a one off, weird episode.
