From the limited information you have provided it is difficult to accurately say if you have heart disease
How old are you? How much do you weigh, your height, your activity level? etc.
Is this your heart rate
when you are resting?
If so, do you have a sensation/awareness of feeling your heart beating which makes you uncomfortable?
Do you have any problems with your thyroids?
Many many questions... would be helpful if you provide more detail so everyone could help you.
