when jogging on a treadmill, I have been getting a really panicky feeling when my heart gets about 165 bpm and I feel light headed, sometimes it feels like my heart wont slow down and I get scared. What could that be? I am 29 years old and exercise regularly, but getting my HR up above 165 has always been scary.
