Has anyone had any experience of heart pacemakers /defibriillators?
i have recently been in hospital with atrial fibrillation and was discharged with drugs which make me feel awful. The alternative was a pacemaker.
Has anyone experienced any problems with these from microwave frequency emitting devices - phone/ phone masts/ DECT phones/ Wifi / smart meters? Or aircraft. Or anything else?
Thanks

Hi AF,
Copied from iPhone manual, page 147:
Medical devices: iPhone contains radios that emit electromagnetic fields. These electromagnetic fields may interfere with pacemakers or other medical devices. If you wear a pacemaker, maintain at least 6 inches (approximately 15 cm) of separation between your pacemaker and iPhone. If you suspect iPhone is interfering with your pacemaker or any other medical device, stop using iPhone and consult your physician for information specific to your medical device. iPhone has magnets near the bottom, and the included headphones also have magnets in the earbuds, which may interfere with pacemakers, defibrillators or other medical devices. Maintain at least 6 inches (approximately 15 cm) of separation between your pacemaker or defibrillator and iPhone or the earbuds.

Keep your Blackberry device away from medical devices, including pacemakers and hearing aids, because they might malfunction and cause serious harm or death to you or others.

This just in:
"Interference between Active Implanted Medical Devices and Electromagnetic Field Emitting Devices is Rare but Real: Results of an Incidence Study in a Population of Physicians in France" Hours et al. Journal of Pacing and Clinical Electrophysiology, 13 Sep 2013:
http://onlinelibrary.wiley.com/doi/10.1111/pace.12269/abstract
Conclusion: Although minor, the risk of interference between EMF sources and AIMDs is real and calls for vigilance. It particularly concerns antitheft and airport security gates, though other sources may also cause incidents.

Dick Cheney, former U.S vice president had the wireless disabled on his pacemaker due to fears that a terrorist could remotely send fatal shock.
More on the Washington Post.
excerpt: Cheney has a history of heart trouble, suffering the first of five heart attacks at age 37. He underwent a heart transplant last year at age 71.
Wow. Almost sounds as if he was meant to die early. What would the world have been like then?

http://onlinelibrary.wiley.com/doi/10.1111/pace.12270/abstract Implantable Cardioverter Defibrillators in Electric and Magnetic Fields of 400 kV Power Lines
Keywords: implantable cardioverter defibrillators; electric and magnetic fields; power lines Background Implantable cardioverter defibrillator (ICD) therapy has increased in Western countries. The aim of the study was to investigate the function of ICDs using a human-shaped phantom in electric and magnetic fields of 400 kV power lines.
Methods The phantom was used in the following manner: isolated from the ground, earthed from a foot, or earthed from a hand.
Results We performed 37 ICD tests using 10 different ICD devices. When the electric fields varied from 6.8 kV/m to 7.5 kV/m (humidity 70.5%) and the magnetic field was 2.0 T, one of the ICDs tested recorded 258 ventricular beats/min when a simulated heart signal was applied to ICD electrodes. When the exposure was 5.1 kV/m, the same ICD had a similar disturbance; however, in a 0.9 kV/m field, it worked correctly.
Conclusions Consequently, no effect on ICDs functioning was observed up to 0.9 kV/m, while anomalous behavior in some conditions was observed when levels exceeded 5.1 kV/m; ICD malfunctioning seems possible within 11.5 m from 400 kV power lines or in conditions inducing exposures exceeding 5 kV/m. Further development of this research field is needed.

Jan 08, 2010—A study published this month in a medical journal shows that while interrogators of passive RFID tags do cause some electromagnetic interference to implantable pacemakers and implantable cardioverter-defibrillators (ICDs), the devices pose no urgent health risks. However, the study's authors believe that the "continued proliferation of RFID without taking implantable pacemaker and ICD EMC into consideration could potentially cause clinically significant events for patients." - See more at: http://www.rfidjournal.com/articles/view?7307#sthash.xQoFXzw2.dpuf

Do any EHS members of the forum have a pacemaker or ICD? If so, what has been your experience?
