Unlike phones, which are commonly held to the ear, music is now available via portable MP3 players and they can be held almost anywhere. Thaker et al state that Apple iPods cause pacemaker interference in 50% of their patients, with over-sensing in 20% of patients, telemetry interference in 29% of patients and pacemaker inhibition in 1.2% of patients (6). The mean age for their sample was 76.1 years +/- 8.6 years. We anticipate that a higher proportion of teenagers and kids who have pacemakers use portable MP3 players than in the elderly adult population.
