In this recording we see two permanent pacemakers working at the same time. The ventricular pacemaker at a rate of 40/min., while the dual chamber pacer is set at a rate of about 80/min with an AV interval of about 160 ms. The atrial lead of the dual chamber pacemaker is capturing and sensing the atrium. The ventricular lead is not capturing the ventricle. There is no native rhythm from the patient seen here.
