Has anyone ever had this?? I feel like every 10 seconds or so, especially on my exhale, my heart jumps. It's the weirdest feeling in the world!! It's been happening for months but on and off. I tried to bring it up to the doctor so he gave me an ekg which was normal. He chalked it up to anxiety. I'm afraid it's so much more than that!! Ugh if anyone has felt this can you please respond. I've had a racing heart. This is totally different. It jumps. Or restarts. Or something!
