Bounding pulse while day and when lying on bed??

[electricpower177]

So i have POTS and probably innapropriate sinus tachycardia,the problem is while lying on bed i fell strong,throbbing pulse in my chest,wrist,fingers,neck etc and can calculate my heart rate without even putting my fingers on wrist as my whole body feels and hear every ******* beat and even all day when im sitting or relaxing i have strong beat in my chest thats bit discomforting..My blood pressure and pulse rate however remains normal.

ARE THESE SYMTOMPS REALTED TO POTS AND IST??
