For the past 2 years i have had palpitations which was recently diagnosed as pvcs and pacs they got better for a while now since october ive had bad palpitations, nausea, shortness of breath, and sometimes i wake up out of my sleep gasping for air. All i think about are my symptoms . It drives me crazy that i cant focuse on anything to get my mind off of this . When i eat my heart pounds so fast and hard and wen i stand up i get even more short of breath . I have no clue what can be causing all of this but i feel lost and hopeless .
