Authors not listed · 1972
Early 1972 research recognized electromagnetic interference with medical devices as a serious safety concern that remains critical today.
Plain English Summary
This 1972 journal article in Medical Instrumentation examined electromagnetic energy interactions with medical devices, particularly cardiac catheters. While specific findings aren't available, the research addressed early concerns about electromagnetic interference with life-critical medical equipment. This represents foundational work in understanding how EMF sources could affect medical device function and patient safety.
Why This Matters
This early medical research highlights a critical aspect of EMF exposure that often gets overlooked in consumer discussions: the vulnerability of medical devices to electromagnetic interference. In 1972, researchers were already investigating how electromagnetic energy could disrupt cardiac catheters and other life-saving equipment. Today, this concern has exploded as hospitals fill with wireless devices, smartphones, and complex electronic systems that all generate EMF.
The reality is that medical device interference represents one of the most immediate and measurable impacts of EMF exposure. Unlike long-term health effects that take decades to study, device malfunctions happen instantly and can be life-threatening. Modern pacemakers, insulin pumps, and monitoring equipment face constant electromagnetic challenges that didn't exist when this research began 50 years ago.
Finding
Simultaneous, instantaneous pressure and flow signals are obtained. These signals are multiplied to obtain cardiac power which is Integrated for stroke-work. Similarly, pressure divided by flow gives Instantaneous impedance which is Integrated for stroke impedance.

Pulsed electromagnetic energy appears to reduce swelling, pain duration, and local distress in patients undergoing mandibular third molar surgery. Additionally, patients treated with electromagnetic energy had a significantly lower incidence of osteitis (dry socket).
