I has a stent put in 1year ago. All of asudden my heart rate increased 108 to 112 resting. Had a nuclear stree test done results are normal. Doctor had already increased my Cardizem Cd to 360 in Am <180 at night. Heart rate was good for 2days ,around 80 . Yesterday I flt like my chest was going to explode. Took Maltha and 2 nitro, pain went away..
Many times a day I fel a chest discomfort that lasts for seconds,sometimes it feels like someone blew a bubble in my chest. Doctor feels all test are okay I could be feeling the racing in my heart. I"m decafinated and can't take beta blockers because of a history of asthma. Haven't used inhalers in years. Any ideas.. I'm afraid of an Aneursym
