<s>[INST] can an ekg reading dx left atrium problems? my 15 year old daughter has been suffering from fatigue and headaches for 4 months.  It is so disabling that she hasn't been able to attend school for 60 days.  she had an ekg done and the doctor reported that she has hypertrophied enlargement of her left atrium?  Can they get this information from one test? [/INST] Hi,ECG is not as informative to diagnose left atrial hypertrophy. I would advise you to have an echocardiography done, if it comes back normal, then nothing to be worried.Take careCome back if you have any further questions </s>
