Shown below is an EKG depicting bigeminy. The pacemaker is an atrial pacer set at 30/min. Note the marker channel documenting atrial pacing and then sensing of the [[QRS]] in the [[refractory period]] of the pacemaker. The paced atrial beats seem to stimulate a normal sinus beat and hence create the bigeminal rhythm. | |||
