question: I have premature pvcs, which are rampant now because I have been battling bronchitis for over two months. Tonight my bp was 142/96. Had sudden sharp pain under right breastbone and under right arm. It was accompanied by a feeling like you get before you pass out. I do pass out from time to time due to vasal issues. It came on me so sudden and even ten minutes later, which is now, I have the feeling. The pain right now is under my left breast bone and my teeth hurt. Am I having a heart attack?
