HEART

HELLO I AM 25 YEARS OLD / FEAMALE. WHO IS OVERWEIGHT I TAKE TOPROL XL 50MGS AND I USE TO TAKE MAGOXIDE BUT STOPPED FOR NO REASON BUT I WAS WONDERING IF SOME PEOPLE CAN FEEL THERE HEART BEATING THROUGHOUT THERE BODY WHILE AT REST OR SITTING STILL CAUSE I CAN DO THIS AND IT SCARES ME AND ALSO SOMETIMES I CAN FEEL MY HEART LIKE FLIP UP IN MY THROAT AND SKIP. BUT IT MOSTLEY DOES THIS AFTER I EAT..IT SCARES ME BAD..I HAVE HAD A ECHO DONE AND IT SHOWED A SLIGHTLY ENLARGED HEART WHICH THE CARDIOLOGIST TOLD ME JUST TO LOOSE SOME WEIGHT AND I SHOULD BE FINE BECAUSE IT WASENT BAD AND THAT ALL I HAD TO DO WAS FOLLOWUP WITH MY DOCTER.. SHOULD I LISTEN TO HIM OR WHAT???
