Is There a Risk for Interaction Between Mobile Phones and Single Lead VDD Pacemakers?

31 patients with single lead VDD pacemakers (12 Unity, 292-07; 10 Thera VDD, 8948 or 8968i; and 9 Saphir 600).

Exposure to a cellular mobile phone with a power of 2 W (D-net) placed in direct contact with the patient's skin at the right sternal border (within 5 cm of the pacemaker connector) during multiple phases of phone calls, with pacemakers programmed to their most sensitive values (A: 0.1-0.25 mV; V: 1.0 mV) and unipolar ventricular sensing.

Pacemaker interference detected via continuous ECG monitoring and changes to programmed values.safety
