Hi kjt1,

I too have had heartrate issues since my concussion (I am 10 months pcs). My normal resting hr is around 70, but I have had times where it has been in the 90s and even 100-110 at rest. Needless to say it concerned me that I felt as though my heart was going to jump out of my chest.

This happened a lot during the first few months, and has occurred on occasion since. However, unlike you, mine was not exercise induced, it just happened at random times. I personally ended up seeing a cardiologist and having an ekg, ultrasound & holter monitor, all with normal results.

I still to this day am baffled by the whole thing. I am glad I got it checked out, if just for peace of mind.

Keep us posted, sending well wishes your way! P
