High voltage power lines produce EMI

EMI at an Electric Power Plant A study was conducted on electromagnetic interference (EMI) measurements at a Midwest electric power plant as it relates to interference with the proper functioning of a worker's Medtronic CRDM cardiac pacemaker/defibrillator.  The power plant operator has an implanted Medtronic CRDM device. Stuart D Bagley, MS CIH CSP of IAQ-EMF Consulting Inc. conducted the electromagnetic field interference (EMI) survey at various locations in and outside of the plant...

Electromagnetic compatibility, or EMC means that a device is compatible with (i.e., no interference is caused by) its electromagnetic (EM) environment and it does not emit levels of EM energy that cause electromagnetic interference (EMI) in other devices in the vicinity. A medical device can be vulnerable to EMI if the levels of EM energy in its environment exceed the EM immunity (resistance) to which the device was designed and tested. The different forms of EM energy that can cause EMI are...

Magnetic Resonance Imaging (MRI) uses powerful magnetic waves to produce images of the soft tissue on the interior of the human body. Many patients with implanted heart devices are not eligible to have an MRI scan because their pacing systems are not approved for use during an MRI scan or near MRI scanners. A new model of implantable cardioverter defibrillator (ICD) which is resistant to the MRI’s strong magnetic fields has been tested at Golden Jubilee Hospital in Clydebank, West...
