This case report is kindly provided by Michael Rosengarten from McGill and is part of the McGill Cases. These cases come from the McGill EKG World Encyclopedia.
This is an ECG strip and an audio recording from a patient checking his Medtronic VVI pacemaker over the telephone. This was a good quality transmission. Part of the printout of the rhythm strip is below. Note the 4 fast beats at 100/min. near the end of the recording indicating that the patient has placed the magnet properly over the pacemaker.
