This is a rhythm strip recorded from a man attending the pacemaker follow-up clinic.

The Patient had been implanted with a dual chamber pacemaker one month before. The pacer was programed to VVI mode and AAI mode and ECG recordings were made. Also a PA and lateral chest x-ray was taken. The questions are: Is the pacemaker working properly? If not what do you think is wrong ?
