The findings come on the heels of another recent study, which examined how electromagnetic interference (EMI) from electrical cars could possibly affect patients with implanted cardiac devices. For example, that study looked at whether it is possible that the devices, which work by measuring electrical activity in the heart could misinterpret signals from electrical or magnetic objects as a potential sign of distress coming from the patient's heart. In some preliminary tests in the new study, the researchers determined that the highest EMI was measured while vehicles were being charged. But the patients were not affected by the high EMI emitted from the charging vehicle, according to the study.

In the study, the researchers recruited 26 men and eight women between the ages of 46 and 85 who were patients at Good Samaritan Hospital in Dayton, Ohio. All of the patients had stably functioning cardiac implants. Some of the patients had a single-chamber implant [ https://www.livescience.com/59830-pacemaker-arson-case.html ], while others had dual-chamber or biventricular implants, which were made by different manufacturers. (A single- versus dual-chamber implant refers to how many of the heart's four chambers the device works on.) Using an electromagnetic field meter, the researchers found that the highest EMI was measured close to the charging port and on the floor of the back seat of a 2016 Tesla Model S P90D while the vehicle was being charged at 220 volts, according to the study. Then, the researchers monitored the patients as they sat in the driver's seat, the passenger seat and the back seat, and as they stood next to the charging port. The researchers also adjusted the sensitivity of the patients' implanted devices to see if they responded to any EMI at their least and most sensitive settings. The study showed that electromagnetic signals from the vehicle's battery didn't interrupt the normal functionality of the patients' cardiac implants [ https://www.livescience.com/10756-electric-vehicles-face-charging-challenges.html ] as they switched to different positions in the car or stood at the charging post, regardless of their device's sensitivity settings. The implants weren't affected because the amount of EMI generated by electric vehicles is very small, thus making them safe for people with an implanted cardiac device, according to the study. The findings were presented today (Nov. 13) at the American Heart Association's Scientific Sessions 2017 in California. They have not yet been published in a peer-reviewed journal.

That's the finding from a new study of 34 seniors who had the devices, which help guard against dangerous irregular heartbeats. The study "demonstrates the safety of the Tesla electric vehicle in patients with cardiac defibrillators and is the first step in establishing that these vehicles are safe for patients with cardiac devices," said Dr. Apoor Patel, who reviewed the findings. Patel is a cardiac electrophysiologist at Northwell Health's Sandra Atlas Bass Heart Hospital, in Manhasset, NY. He believes the study will "need to be replicated [in] other vehicles," but also noted that "the Tesla generated the most electrical activity during charging." The new study was led by Drs. Thein Tun Aung and Abdul Wase, of Good Samaritan Hospital in Dayton, Ohio. The findings were to be presented Monday in Anaheim, Calif., at the annual meeting of the American Heart Association. As Patel noted, "although electric vehicles are a small part of the total U.S. car market, sales are growing 30 to 40 percent annually." And there's been concern that electric vehicle technologies might somehow interfere with pacemakers and implanted defibrillators. To help settle the question, the Dayton team tracked outcomes for 26 men and eight women, averaging 69 years of age. All had an implanted cardiac defibrillator. The participants' devices were monitored for electromagnetic interference as they were in or near a Tesla S P90D as it was charged at a 220 volt charging station. People were tested in a variety of positions—sitting in the driver's seat, passenger seat, backseat and while next to the charging port. The tests—done even at the defibrillators' most sensitive setting—showed that the devices "did not sense the electromagnetic signal from the electric vehicle battery," according to an AHA news release. There was no evidence that being in or near the car while it was charging triggered a shock from the defibrillator or otherwise interfered with it, the researchers said. Dr. Khabir Bjasin directs cardiac electrophysiology at Lenox Hill Hospital in New York City. He explained that theoretically, at least, any electronic device might send out signals that could confuse a cardiac implant into functioning inappropriately. Reading over the new findings, he said that "this study effectively demonstrates that the level of electromagnetic interference emitted by electric vehicles is too low to interfere with [implanted defibrillators]," so people who have them "can safely drive or ride in these vehicles." More study is needed, however, and experts do note that studies presented at medical meetings are considered preliminary until published in a peer-reviewed journal.
