Hi everyone, new here. Have been getting fast heart rate over past 12 months. Ended up in cardio unit in July. Discharged wifh Bisoprolol 2.5mg. Due angiogram and am terrified for some reason. HR not fully under control. One day its 65-75 then for some reason it will shoot up to 112 and stay there for anythjng between 15 min to 8 hours. Live alone and frankly get frightened. Frightened of angiogram as an unrelated procedure went slightly wrong last year.
