My mother is 73 years old is diabetic. recently she has recovered from a burn injury in February 2011. Prior to that ehr ECG was normal, blood sugar also & even BP. Now in June 2011, hr post lunch sugar was 137 mg/dl fasting sugar 70 mg/dl. However, her ECG shows sinus rhythm & contour abnormalitiy consistent with anteroseptal infarct probably old. advise is this serious? for the past few days she is showing some fatigue, indigestion, losing balance a little bit (cholecystectomy done 8 years ago)
