Following this approach with the patient's electrocardiogram, the rate is 70 per minute and the rhythm is normal sinus. The frontal plane axis is within normal limits at +30°. The
P wave that represents atrial depolarization, is normally upright in lead II.
The
QRS that represents ventricular depolarization, is normal, with no pathologic Q waves, evidence of hypertrophy or intraventricular conduction delay.
ST-segments are normally concave, without elevation or depression.
T waves that represent ventricular repolarization, are also normal. They are positive in leads I and V2 through V6, with a more gradual upstroke than downstroke.
The patient's ECG is, therefore, entirely normal.
