jason, i am in the air national guard. during the last four years i have been activated for the iraq war. during this time i started having fainting spells and blacking out. during the last incident when this happened i was rushed to the emergency room and they found the blackouts were being caused by my heart stopping ( sick sinus syndrome ) so i was rushed to surgery and a pacemaker was placed in my chest which will be there the rest of my life. a line of duty letter was completed. i know that they will medically discharge me. i have 20 total years of service in the air guard, with 13 of those years being active duty. upon being medically discharged, will i be able to start recieving a retirement check and medical benefits right away ? and, in your openion, will the medical board rate this condition that i have at 30% or above. thank you for your help sir.
