A normal healthy heart beat is called a Sinus Rhythm, What you are experiencing is known as Sinus Tachycardia. Meaning that the number of beats per minute is elevated above what is “normal”, which is why you are shaking. Now coming from a professional standpoint I would personally go to the Emergency Room, not because i am a pussy or anything but ultimately because like any motor you heart can give out after such abuse. But it depends on the person.
