My heart beat is so powerful my whole body shakes and my chest jumps to each beat, even at rest. I am a very athletic and fit man, 6' tall, 210 lbs and muscular. I weight lift and do martial arts. After exercise my heart is so strong People can see it and hear it beating in my chest if in a quit room. My Dr. Has done EKGs and electro cardio grams and stress tests, and says my heart is strong as a tiger's heart. It seemed the more athletic I get the stronger and louder the beats. Strong heart! Who else out there has this same symptom.
