Having never in my life so far (i am 54) had concerns regarding my heart, i now find myself having tests and checks done as a result of treatment i have had since Feb 2013. After chemo, radio and hormone tablets (started themin Sept) i suddenly began having funny episodes of either dizziness with racing heart or just the sensations of skipped heartbeats/faster than normal rhythm. I had ECG at GP then a stay overnight in hospital with another ECG,Echocardiogram,Heart monitor overnight then sent home with a prescription for Bisoprolol (beta-blocker) and no real explanation as to what was happening - just told to see your GP.
I have to take the beta-blockers for a year at least and was referred to the Anticoagulant unit to be started on Warfarin(apparently with Atrial Fibrillation which is what the hospital wrote in my notes (I didn’t know this) you need Warfarin to prevent strokes. I have refused this as i haven’t even seen the Cardiologist (my june appt was cancelled until aug) and i have not been sat down with anyone to explain what is going on. i feel likei am in limbo and can’t move forward with anything or make plans as i have this cloud hanging over me and anxiety when i feel a bit out of sorts and can’t do anything about it.
I have read a recent report on the Breast Cancer Site (i think this is an American equivalent to this site for B/C patients to chat like we do) that only a small percentage of women actually report that they are getting these symptoms either during or after treatment and they are under the care of Cardiologists now as a result, so i am still convinced (as i was at the beginning of this in Sept) that whatever is going on with my ticker is definitely due to something along the way. I find the problem is we are so overwhelmed with information for each treatment process that you just don’t ever think that things like this would ever occur with you, i jhave seen my Dad have similar problems caused by medication(they seem to have corrected now) and i do not want yet another thing to worry about i just want to get on with my life and be “Normal” again whatever that may be!!
