why does a raised heart rate from an anxiety or a panic attack pound very obviously in your chest while a raised heart rate from exercise doesn’t?

Question

At least in my experience, a sudden rapid heart rate from a panic attack feels like my heart is litteraly jumping around in my chest, but when I’m running and I stop I can tell my heart is beating fast but it’s not “bouncing around in my chest”. The same bouncing thing happens when you nearly avoid a car wreck or some other catastrophic event. If the heart rate is high in both situations, why does one feel more bouncy?

Answer 1

The way I understand it, is your body produces cortisol when you are anxious, so the racing heart plus the cortisol make the sensation worse or feel different.
