"Poor treatment"

My daughter was told by a doctor 3 years ago that she was wasting his time. She had been referred with a heart murmur. (Her father dropped dead at48.after having an ECG which was supposedly clear. )Now it appears this doctor? misread her results and she is to be referred again. She could have a damaged valve. She is 27 years old. What is happening to the NHS? It's dreadful. Nurses were shouting, chaos seems to reign. Places to wait are cramped and murky. GPS are no better. They don't know their patients or connect families or listen properly to patients. It's a disgrace. There is no effective communication between the hospital and GPs either. Letters either come in identical pairs or not at all. So unprofessional. My husband was also misdiagnosed 8months ago by the GP causing an 8 month delay in finding his stage4 oesophageal cancer. Surely this sort of inefficiency costs more in the long run for the NHS
