If a person has heart disease, clogged arteries, what symptoms would manifest. I had a cardiolite stress test done Feb 06 and all ws fine Could things have changed that much in a year? Would my blood pressure be affected, heart rate..etc? I ve worn a holter monitor and am awaiting the results. Office EKG came out normal except for high heart rate which brought me to the doc. He increased my Tenormin which i just started this morning. Last night though i had this weird and scary thing happen. All of a suddent i had this sensation completely on my left side..from little below my shoulder all the way down to my pelvis. hip area and then it passed ..must have lasted about five sec. Scaredme. Any ideas
