Webb9 sep. 2015 · Telling Signs With EKG. When physicians review EKGs, a few telling signs may indicate that the patient has had a pacemaker implanted. In atrial pacing, a pacemaker spike is followed by a P wave with morphology dependent upon the location of the atrial pacer lead. The QRS complex appears as if in sinus rhythm. WebbThe P wave indicates atrial depolarization, the QRS complex indicates ventricular depolarization, and the T wave indicates ventricular repolarization. This tracing demonstrates a normal positive P wave, a negative Q wave, positive R wave, and no distinct S wave in this lead (which is considered a normal variation).
