Electric Cars Don't Interfere with Heart Implants

Fans of Tesla electric cars [
] who also have implanted heart devices can rest easy: A new study finds
that these patients won't run the risk of shock or interference to their
devices when they sit in or stand close to a Tesla while it's charging.
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
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. (Hyperloop, Jetpacks & More: 9 Futuristic
Transit Ideas) [
This proof-of-concept study suggests that "electric vehicles [
] may be safe to use for individuals with cardiac defibrillators [
]," according to senior study author Dr. Abdul Wase, a clinical professor of
medicine at Wright State University's Boonshoft School of Medicine in Ohio,
and his team.
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 [
], 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
] 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.

Motor on, heart patients: Electric cars don't harm cardiac implants
November 14, 2017
(HealthDay)—Heart patients who've bought an all-electric Tesla need not
worry that their car might interfere with their implanted defibrillator.
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
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
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
