Nowadays, most electrocardiogram (ECG) machines are programmed with an automated interpretation program. They use pattern recognition to make ECG diagnoses. At the end of these diagnoses, this automated system concludes one of three things – Normal ECG, Borderline ECG, or Abnormal ECG. This system prompts providers to look for conditions, but often confuses and worries patients. For simplicity, the ECG is only called normal if every aspect is felt to be normal by the ECG machine. Any abnormalities, even ones that are benign and of no clinical consequences. Get labeled as Borderline or Abnormal. If you see Borderline or Abnormal on an ECG, do not panic and ask your medical provider.
