A challenge for pacemaker therapists is whether a patient working in an environment with the potential for electromagnetic interference (EMI) can return to their work after a pacemaker has been implanted. Common practice has been to prohibit pacemaker patients from using electric welding machines. Twelve work environments and a new method for monitoring the pacemaker rhythm in the presence of EMI were tested. The new method uses a special memory called the event record found in several Siemens… Expand
Testing of Common Electromagnetic Environments for Risk of Interference with Cardiac Pacemaker Function
Modern pacemakers are well shielded against external EMFs, and workers with a pacemaker can most often return to their previous work after having a pacemaker implanted, however, an appropriate risk assessment is still necessary after the implantation of apacemaker, a change of its generator, or major modification of its programming settings.

The collected information and data from the literature suggest that welding can be a risk for a subject with PM; as observed in experimental conditions, electromagnetic radiations can alter particular sensitive devices and those with uncorrected settings. Expand
Electromagnetic interference from welding and motors on implantable cardioverter-defibrillators as tested in the electrically hostile work site.
None of the implanted defibrillators tested were affected by oversensing of the electric field as verified by telemetry from the detection circuits, and testing at the work site revealed no electrical interference with this type ofdefibrillator. Expand
Electromagnetic interference in patients with implanted pacemakers or cardioverter-defibrillators
It is accepted practice to advise patients that while airport screening devices may detect the pacemaker or ICD metal case the device will not be adversely affected, and patients should carry their device identification card for the purpose of obtaining security clearance. Expand

This two-part review discusses EMI with implanted cardiac devices and addresses general concepts and specific sources of EMI in everyday life and the workplace. Expand
Patients with an ICD Can Safely Resume Work in Industrial Facilities Following Simple Screening for Electromagnetic Interference
A simple screening procedure can safely identify sources of electromagnetic interference that may affect ICD operation, and can predict long‐term safety of working in an industrial workplace for ICD patients. Expand
Interactions between Pacemakers and Security Systems
The findings indicate that patients with pacemakers should avoid contact with security systems and persons who are often in the vicinity of security systems should be equipped with a bipolar pacemaker system. Expand

Anticipating a correct setting of ventricular sensitivity, currently available pacemakers equipped with feedthru filters do not show any interference with cellular phones, and it is recommended that permanent programming of Ventricular sensitivity should be set at 2.0 mV and higher. Expand


The influence of electromagnetic environment on the performance of artificial cardiac pacemakers.
An effort has been made to determine the sensitivity of 10 types of pacemakers to the effects of low-frequency alternating current in the range of l cycle per second to 100 kilocycles per second and to theeffects of impulses resulting from electrical corona. Expand
Preliminary observations of the behavior of two brands of pacemakers in several environments which may be encountered by patients are reported, to ensure that any induction currents or alterations of function which were detected had originated within the pacemaker unit itself. Expand
The Effect of 50 Hz External Electrical Interference on Implanted Cardiac Pacemakers
Current injection has proved to be a safe, controllable and reproducible method of testing the sensitivity of implanted pacemakers to 50 Hz external interference. Expand
The pacemaker patient and the electromagnetic environment.
This unit monitored the heart rate by sensing the R wave, recycling without firing when the rate was adequate, and firing at an appropriate rate when bradycardia occurred, and the problem of unwanted competitive pacing from the older fixed-rate pacemaker was thus solved. Expand
