i am a young teen and this happens like 6 times a month: in differnet places and times i was just about to fall asleep when my heart stoped for 1/2 a second and then pumped really hard slow, it took my breath away, i breathed in like a gasp really fast, it was the worst it had ever happened i had a heart murrmue when i was born, but docter recently like 2 weeks ago didnt hear anything, we asked him too...? what is this? if i go to a ? specialist how can they test my heart, stick a needle in it? scary i i started realizing i had it this year, he said i grew out of it at 12, but idk it doesnt hurt, just shocking
