EMC’04/Sendai A STUDY ON IMPLANTABLE CARDIAC PACEMAKER EMI FROM CELLULAR RADIOS IN SEMI-ECHOIC ENVIRONMENTS ― FDTD Analysis and Experiments in Actual Train Carriage ―
نویسندگان
چکیده
Theoretical and experimental studies are conducted on the electromagnetic field (EMF) distributions excited inside train carriages and the implantable cardiac pacemaker EMC issue in the same environment. Both precise computer simulations and experiments using 800 MHz and 2 GHz transmitters in an actual train carriage confirm that excessively high EMF, high enough to affect pacemaker normal functions, does not occur inside the carriage provided the safe distance of 22 cm set for pacemaker users is kept. Methodologies are described first. Typical results of FDTD analysis and actual measurement data are then shown. Finally, considerations and conclusions are made.

Estimation of EMI Impact by Cellular Radio on Implantable Cardiac Pacemakers in Elevator Using EMF Distributions Inside Human Body
The purpose of this study is to estimate the possible effect of cellular radio on implantable cardiac pacemakers in elevators. We previously investigated pacemaker EMI in elevator by examining the Efield distribution of horizontal plane at the height of expected for implanted pacemakers inside elevators. In this paper, we introduce our method for estimating EMI impact to implantable cardiac pac...
متن کاملIs correction for metallic artefacts mandatory in cardiac SPECT/CT imaging in the presence of pacemaker and implantable cardioverter defibrillator leads?
Introduction: Metallic artifacts due to pacemaker/ implantable cardioverter defibrillator (ICD) leads in CT images can produce artifactual uptake in cardiac SPECT/CT images. The aim of this study was to determine the influence of the metallic artifacts due to pacemaker and ICD leads on myocardial SPECT/CT imaging. Methods: The study included 9 patients wh...

متن کاملErosive Pressure Dermatitis Associated with Cardiac Pacemaker
Erosive dermatitis is a skin reaction associated with implantable cardiac devices (ie, pacemakers and cardioverter defibrillators). We report a 65-year-old man with a history of several cerebrovascular attacks who developed an erythematous crusted erosive patch over the pacemaker site after implantation of two subsequent pacemakers. We suggest that physical irritation may be a trigger factor fo...
متن کاملElectromagnetic Interference in Implantable Rhythm Devices - The Indian Scenario
Implantable rhythm device (IRD) is the generic name for the group of implantable devices used for diagnosis and treatment of cardiac arrhythmias. Devices in this category include cardiac pacemakers, implantable cardioverter defibrillators and implantable loop recorders. Since these devices have complex microelectronic circuitry and use electromagnetic waves for communication, they are susceptib...
