When I took my blood pressure today, I was feeling those spasms that I have felt in the past which feel like they occur in the middle of my chest. they make me feel just a little out of breath so much so that it causes me to cough at times just a little. when I took my blood pressure this morning, the readings were like 151/127 and then 118/78. It also showed the irregular heart beat symbol. These types of things have happened in the past, but stopped for a period of time and then the spasms have recently come back again. My doctor recently put me on lisinopril for high blood pressure. I wish I could find out what causes these feelings in my chest. I do work grave yard shift and my wife thinks maybe my change in schedule and lack of sleep have caused my health problems. What do you think?
