Summary

Description

This is an interesting case of bigemini. The pacemaker is an atrial pacer set at 30/min. Note the marker channel documenting (labels should be AP and AS) atrial pacing and then sensing of the QRS in the refractory period of the pacemaker.

The tracing is curious as the paced atrial beats seem to stimulate a normal sinus beat and hence create the bigeminal rhythm.
