Good morning, doctor. I live in a small town in Holland, I'm a 54 year old female, infected with limes disease 20 years ago, many problems with my health as a result. Recently I had to have a septum correction but the anesthesiologist called me a ASA 3+ plus patient so I could not be fully sedated. Several things went wrong during the operation, I asked for a copy of my file. They won't give me everything, but I have a page where it says; ECG SR. They won't tell me what that means. Can you tell me? Thanks.
