Key result
Exposure to digital (GSM) and analogue (TACS) cellular telephones caused pacing interference in 21.5% and 17.5% of pacemaker patients, respectively, with higher risk during ringing (P<0.0001).

Do digital and analogue cellular telephones cause electromagnetic interference in patients with implanted pacemakers?
Absolute Event Rate: 21.5% vs 17.5%
Cellular phones can cause electromagnetic interference in pacemakers, particularly during ringing and at maximum sensitivity, but are safe if not carried close to the device.
Altamura et al. (1997) conducted an observational in implanted pacemakers (n=200). Global System for Mobile Communications (GSM) telephones vs. Total Access of Communication System (TACS) telephones was evaluated on pacing interference. Exposure to digital (GSM) and analogue (TACS) cellular telephones caused pacing interference in 21.5% and 17.5% of pacemaker patients, respectively, with higher risk during ringing (P<0.0001).
