Hi - before xmas, DS (7yrs) had a terrible pain in his chest quite out of the blue. We were all chatting in the kitchen when he suddenly gripped his chest and throat and said he couldn't breathe.
I was really worried and about to take him to A & E but sat him on the worktop and calmed him down until it stopped.
Since then, he has complained a few times saying "my heart hurts" and so I kept checking his heart whilst he was sleeping. It felt all over the place, mainly as though it was coming out of his chest and really fast. Even though I felt it at rest, it also felt as though it was doing an extra beat; kind of like.........
bum, bum
bum, bum
bum, bum
bum, bum,bum ,bum
bum,bum
(IYSWIM?)
So a few weeks ago I had him checked out with the GP who listened to his heart for a couple of mins and said she thought it was arrhythmia, common in children. She said if he got pains again, to take him back and that she thought the down beats were faster than the up beats (sort of how she worded it 
.
I'm still owrried he wasn't sent for an ECG - should I take him back or does this sound common?
