Mobile phones showed no interference with pacemakers even in direct contact at 2 watts, higher than today's typical smartphone emissions.

Plain English Summary

Summary written for general audiences

Researchers tested whether mobile phones could interfere with single lead VDD pacemakers (a specific type of heart device) by placing a 2-watt cellular phone directly on the skin of 31 patients near their pacemakers. They found no interference with any of the three different pacemaker models tested, even when the devices were programmed to their most sensitive settings.

Therefore, the risk of interference seems to be low for the VDD pacemakers tested, although our study design does not allow to entirely exclude the possibility of interference from a mobile phone.

Quick Questions About This Study

A 1996 study tested 2-watt digital phones directly on the skin of 31 patients with single lead VDD pacemakers and found no interference with any of the three different pacemaker models tested, even at their most sensitive settings.
Research shows single lead VDD pacemakers appear safe around D-net digital mobile phones. When researchers tested 31 patients using 2-watt phones placed directly on skin near the devices, no interference occurred with any pacemaker model.
No, VDD pacemaker settings remained completely unchanged after mobile phone exposure in a 1996 study. Researchers found that programmed values stayed the same even when 2-watt digital phones were placed directly on patients' skin.
The 1996 study tested three different types of single lead VDD pacemaker models for mobile phone interference. All models showed no interference when exposed to 2-watt digital D-net phones, even at maximum sensitivity settings.
Direct skin contact between digital phones and VDD pacemakers appears safe based on 1996 research. Scientists placed 2-watt phones directly on patients' skin near their pacemakers and detected no interference, though complete risk exclusion wasn't possible.
