In summary, electrocardiographic interpretation is anchored on the objective reading of the ECG without the advantage of seeing and/or knowing the patient when the electrocardiographer is isolated in the heart station. When the electrocardiographer is the attending physician, the advantage of knowing the patient may create a favorable bias in the interpretation, leading to a clearer understanding of the ECG and correct diagnosis
Separating the normal from the abnormal tracing is of primary concern to any electrocardiographer. Sorting out the types of abnormalities is the second step. Done this way, the ECG becomes an important diagnostic tool in providing excellent cardiac care delivery.
