These are two strips from a 90 year old patient with a pacemaker. The pacemaker was past end of life and one paced beat can be seen in the top strip. Note the pacemaker was not sensing at this time. The patient's rhythm is complete heart block (note the slight variation in the pr interval which supports this interpretation)
