I am a 43 year old male, in great physical shape, not overweight, eat pretty healthy. Over the summer last year I thought I was having a heart attack, my heart was squeezing, relaxing then squeezing again which went on for a while. I called 911 & while waiting it got worse & then I became sweaty, neauseous & threw up. When they began a work up of me they saw that I was having PVC's & brought me to the hospital. The PVS were high, my pressure was through the roof yet the enzyme test came back normal & they discharged me after a few hours. I went to a cardiologist who did an EKG, echo & stress test all of which came back normal. No structural damage to the heart, no blockages. I am on Metoprolol (spelling??) 100 mg/day. I was also prescribed Adivan for sleeping, Xanaax for anxiety which my doctor is attributing to these episodes. They are a daily occurence, happening throughout the day, my heart squeezes, relaxes, squeezes, like someone holding you finger in a closed grip and a sudden squeze from time to time.Any comments please?
