during my hiking when I get on some steep areas I notice that I can feel my heart beat in my neck and ears.... but as soon as it get less steep it tends to go away! Is this normal? I have no other symptoms or history of heart problems. resting HR is normally high 50s to mid 60s, work out or hike 3 to 5 times a week BP is normally between 125/70s to 140/ over 70s depending on the day. Blood sugar is always good and cholesterol is very low though my good cholesterol has always been on the low side.. Have had treadmill, event monitor, holter monitor, ultrasound and EKGs done in the last 10 years and no signs of problems.
