This electrocardiogram is within normal limits.
The characteristic features demonstrated here include a normal sinus rhythm with seventy-five beats per minute. The frontal plane axis is within normal limits at plus thirty degrees. The P wave is upright in lead II. The QRS shows no pathologic Q wave, evidence of hypertrophy or intraventricular conduction delay. The ST segments are normally concave, with no pathologic elevation or depression. The T waves are positive in leads I and V2 through V6, with a more gradual upstroke than downstroke.
