Lately, about once every couple days or so or even less, i can feel my heart skip a beat. Sometimes it's realy mild, like the heart is just skipping, but the very last time it was like my heart had like a seizure. I could feel it, it almost set off a panic attack as soon as i felt it i almost went into shock i thought my heart was gonna stop. It specifically felt like it was having a seizure, and i've heard about most people don't even notice their hearts skip, but this was too noticable. Any thoughts?
