The Employee Wearing a Cardiac Pacemaker
Donald R. Koerner, M.D. · 1974
This 1974 study documented early evidence that workplace electromagnetic fields could interfere with cardiac pacemakers.
Plain English Summary
This 1974 medical study examined electromagnetic interference risks for employees with cardiac pacemakers in workplace environments. The research focused on occupational exposures from sources like microwave equipment and diathermy devices that could potentially disrupt pacemaker function. This represents early recognition that electromagnetic fields could interfere with medical devices.
Why This Matters
This pioneering 1974 research highlighted a critical safety issue that remains relevant today: electromagnetic interference with medical implants. While pacemaker technology has advanced significantly since then, the fundamental concern about EMF disrupting electronic medical devices persists across our increasingly wireless world. What makes this study particularly significant is its early documentation of real-world EMF interference effects on human health technology. Today's pacemaker wearers face exposures from WiFi routers, cell phones, and security scanners that didn't exist in 1974, yet the core vulnerability remains the same. The science demonstrates that certain electromagnetic frequencies can indeed interfere with the electronic circuits that keep hearts beating properly.
Exposure Information
Specific exposure levels were not quantified in this study.
Study Details
To examine potential hazards to cardiac pacemaker dependents in occupational and home environments, particularly concerning interference from electromagnetic fields and electrical devices.
Although reported clinical pacemaker malfunctions from external interference are relatively infrequent in relation to the number of patients dependent upon them today, the potential seriousness of adverse effects for such patients, especially those wearing a demand type unit, requires an awareness of the problem on the part of occupational health personnel. Employees wearing pacemakers and the type worn should be identified and recorded. Medical personnel should know the symptoms and signs of possible pacemaker malfunction as well as familiarizing themselves with the various types of pacemakers and the individual peculiarity of interference response by each type so that adverse effects can be promptly recognized. The employee's supervisor should be briefed concerning significant symptoms. Areas of potential interference hazard should be identified and prohibited as working sites. Safety personnel should ensure proper grounding of electrical equipment used by the employee and should conduct frequent surveillance of possible sources for EMR not only in the employee's work site but also in other areas of more casual exposure. Service technician calls should be regularly scheduled for apparatus which could inadvertently produce high levels of EMR exposure. An effort should be made to ascertain the degree of indoctrination provided by the private physician concerning potential hazards to the performance of the employee's pacemaker. This in turn should be reinforced and augmented by counseling concerning any special conditions pertinent to potential pacemaker interference existing in the employment site environment.
