<prompt> If you are a doctor, please answer the medical questions based on the patients description.hi , i have a raised esr level and have just had an ecg which showed some sbnormalities in the qrs reading , what does this mean for me i am female aged 59 had breast cancer 18 months ago stage 1 grade 1 no lymph nodes involved. i have had a pesistent cough for 1 year on and off.  <response>: Good Day, ESR is a very nonspecific reading. A great number of things can raise these values, and one large value does not necessarily represent any significant illness or issues; it will not be enough to say anything is wrong or right. What it can do is signify that your body is in a more inflammatoryreactionary state than usual; but as I stated before this can be due to a number of things Stress, elevated BP, viral or bacterial illness even simple colds that you dont realize you have. Are you suffering any other symptoms? I hope this has helped, I wouldnt place too much emphasis on your ESR by itself, but if there are any other symptoms, Id be happy to discuss these with you.
