Ihave been having these symptoms for almost a year. I get tightness in my upper chest and sometimes my neck. Every two or threes months I will have a near syncopal epsiode. Sometimes associated with a short quick walk or slow stride up a filght of stairs. I get very dizzy, sometimes tunnel vision. I usually have to set down or put my head between my legs. This is accompianied by a feeling of SOB. Although I feel like I am exchanging air at the time. The new symptom is the feeling of my heart skipping a beat. This has happen the last couple of days. I have a high family history of heart and stroke disease. I have been taking Vitoran for almost three years for high colestoral, It is now under 175 with a ratio of 3 to 5. When the symptoms started I had an EKG, stress test and stress echo. These have all been normal. I even had a heart cath, which showed a 30% narrowing of my anterior desending coronary artery and a couple of lesser narrowings in two other vessels. I take paxil (20mg) a day for depression. I have taken this for over 10 years. My job is often stressfull, but I am an even keeled non flustered individual. Everytime I go to the doctor things check out normal. I am beginning to fill like I m going crazy and am becomming increasings concerned.
