Below are two parts of a rhythm strip from a woman who was implanted with a Medtronic Myrel VM VVI pacer in 1983. This is a VVI.O pacemaker with a rate of 72/min. The strips below where received by transtelephonic transmission for a routine pacemaker check! (see instruction for transmission) The upper strip is with no magnet applied, the lower trace is the end of the period where a magnet was placed over the pacer. What do you think of the patient's rhythm? Is the pacemaker working well?.

This is the last part of the transmission where a magnet was placed over the pacemaker.
