I'm experiencing this odd sensation in my chest where it feels like my heart is having a spasm or beating irregularly for a few seconds. It's not exactly painful, just really weird, and it's been happening every few months. Sometimes it even feels like its happening in my right chest or arm, which made me think it might be nerve-related. I've had heart tests done in the past, and everything came back normal, but this sensation worries me. Also, whenever I stand up or walk upstairs, my heart rate jumps up to 150 bpm and then drops back to 100 bpm shortly after, which makes me wonder if I could have POTS. I often forget to check my pulse when this happens because it scares me so much. Could these spasms be related to muscles or nerves instead of my heart? Is it normal to experience this kind of chest pain and heart sensations for just a few seconds?
