for about the past three years ive been having a lot of heart issues. Ive been overweight my entire life. im a 22 year old male. I am 6'0" and 300lbs (dont tell me i need to lose weight i know that..working on it now) i have a constant rapid heart beat (110-120resting) and constant palpitations. i have a history of heart disease in males on both sides of my family.

Ive been hospitalized countless times for my condition. But they wont do any real testing because i cant afford insurance. so far what i know is that there is a problem with my sinus node
and i need a surgery i think they called it an ablation or something. first what could be causing my sinus node to mis fire like it does and second what is the prosedure? cost? and general prognosis...also lets pretend im a worst case scenario . what is the chance of a heart attack at my age and current health? thank you so much any information will help..

also smoke a pack and a half a day...yeah i know! i know!
