I am a 52 year old female, 183 lbs. Normally healthy. When I sit back in a recliner I have a very heavy feeling in my chest and have the feeling I need to gasp for air. My blood pressure is normally 95/60. At the dr's yesterday it went up to 136/80 but after a few minutes went down to 116/60. There are times I can feel my heart beating very hard and I can feel this in my throat. It also feels like someone is grabbing my throat and squeezing. The dr. has scheduled an echo stress test for next week. With the echocardiogram and cat with dye being normal he feels it could be my heart skipping a beat. Last night it felt like it was skipping every other beat. I was very lethargic and uncomfortable. Any ideas?
