i have rapid resting heart rate. about 90 per min. does that mean when i exercise, i will be panting more than others and also take a longer time to cool down?

is it normal to be able to feel your heart beat...like one beat tt feels something like a burp? feels abit like gas escaping but nv reach ur throat? i dun know how to describe but i have this feeling sometimes. sometimes also i can feel one strong beat , feels like e heart suddenly got very near my skin surface.

If you have a rapid resting haert rate because of lack of fitness, then yes, you will be out of breath more easily when exercising, and it will take longer to recover.

As for feeling your heart beat... I'm not sure what you're describing, but I often feel my heart beat. For me it's absolutely normal.

90 bpm is a normal resting heart rate. On the high side of normal, but still normal.

However, yes the fact that your resting heart rate is on the high side means that you're probably not in shape and will therefore tire more easily during exercise, until you have become more fit.
