Summary

Description

This is an electrocardiogram from a 87 year old man with a history of atrial fibrillation. His medications were coumadin and Monopril. The cardiogram shows sinus rhythm with rate of about 50/min, and a marked first degree heart block with a pr interval of about 350ms.

The first complex on the left is a fusion between the patient's native QRS and the pacemaker spike (this is nomal operation) this is followed by a PVC. Note the small blip following the PVC is artifact and is not a failure to capture of the pacemaker. The pacemaker is working well as a VVI pacer set at 50/min. The large spikes suggest a unipolar lead.
