London: If you wear a cardiac device such as a pacemaker, better keep away from smartphones, researchers say.

“Pacemakers can mistakenly detect electromagnetic interference (EMI) from smartphones as a cardiac signal, causing them to briefly stop working,” said first author Carsten Lennerz from German Heart Centre, Munich.

“This leads to a pause in the cardiac rhythm of the pacing dependent patient and may result in syncope.”

“For implantable cardioverter defibrillators (ICDs) the external signal mimics a life threatening ventricular tachyarrhythmia, leading the ICD to deliver a painful shock,” Lennerz said.

Device manufacturers and regulatory institutions including the US Food and Drug Administration (FDA) recommend a safety distance of 15 to 20 cm between pacemakers or ICDs and mobile phones.

Now, new cardiac devices are in use including ICDs, cardiac resynchronisation therapy (CRT) and MRI compatible devices.

The current study evaluated whether the recommended safety distance was still relevant with the smartphones, networks and cardiac devices.

A total of 308 patients (147 pacemakers and 161 ICDs, including 65 CRTs) were exposed to the electromagnetic field of three common smartphones (Samsung Galaxy 3, Nokia Lumia, HTC One XL), which were placed on the skin directly above the cardiac device.

The actions were performed in GSM, LTE and UMTS at the maximum transmission power and at 50 Hz, a frequency known to influence cardiac implantable electronic devices. Electrocardiograms (ECGs) were recorded continuously and checked for interference.

More than 3,400 tests on EMI were performed. One out of 308 patients (0.3 percent) was affected by EMI caused by smartphones.

This patient’s MRI compatible ICD misdetected electromagnetic waves from the Nokia and HTC smartphones operating on GSM or UMTS as intracardiac signals.

“Interference between smartphones and cardiac devices is uncommon but can occur so the current recommendations on keeping a safe distance should be upheld.”

“Interestingly, the device influenced by EMI in our study was MRI compatible which shows that these devices are also susceptible.”

The results were presented at the joint meeting of the European Heart Rhythm Association (EHRA) and Cardiostim, which is in Milan, Italy. (IANS)

Around 300 million smartphones — which equates to 19 per cent of the total devices to be sold in 2018 globally — will have a “notch display”, a new report said on Thursday.

Huawei, OPPO, Vivo and Xiaomi smartphones with “notch displays” (a little black cut-out on top of the smartphone screen) are likely to exceed 100 million units in sales in 2018, said market research firm Counterpoint.

“Android smartphones will contribute to 55 per cent of such devices and most of the tier-one Android Original Equipment Manufacturers (OEMs) will embrace ‘notch displays’ in their flagships first,” Counterpoint added.

The adoption of “notch displays” in sub-$200 price segments from tier-one brands will depend on competitive pressure and consumer feedback.

Cupertino-headquartered Apple will lead the segment by capturing 45 per cent of devices with “notch displays”.

Apple is also expected to adopt “notch display” in its next series of iPhones.

Android creator Andy Rubin’s Essential Phone was first to embrace the “notch display”.

iPhone X users decided to embrace the notch and the trend has recently shifted to Android camp with tier-one brands launching their flagships with notch displays.

Smartphones such as Asus Zenfone 5 was launched during Mbile World Congress (MWC), followed by OPPO F7, Vivo V9, Huawei P20 and P20 Pro are some devices that feature notch screen design.  (IANS)
