Cardiac device wearers should maintain distance from smartphones, says a research

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)

Chinese smartphone manufacturer Huawei’s President for 5G product line, Yang Chaobin believes that 5G smartphones priced around $150 are expected to be launched by the end of 2020 or in early 2021.

Huawei, along with its sub-brand Honor, has launched a number of 5G smartphones in 2019, including Mate 30 5G series, Mate 20 X 5G, Mate X 5G, Nova 6 5G, Honor V30 series, among others, news portal GizmoChina reported on Friday.

Recently, the company announced that it has shipped 6.9 million units of 5G smartphones as of December 2019, in addition to offering end-to-end 5G solutions. Additionally, Chinese local research agencies suggested that 20 per cent of all mid range smartphones will support 5G, thanks to the expansion of the network in the country.

An estimated 5 million 5G capable smartphones were sold in December 2019 alone. It is expected that more than 20 per cent of the smartphones under $290 will be 5G-enabled this year.

By 2021, the same statistics are expected to be applicable across the globe. Xiaomi co-founder Lei Jun recently announced the company is planning to pump $7 billion in 5G, AI and IoT over the next five years.

Earlier, Lei had also revealed that the company is planning to release more than 10 5G phones this year. US-based investment banking and financial service company Goldman Sachs has also forecasted a hefty 200 million 5G smartphone shipments globally this year.

The new predicted value is about 20 times more than the sales figure of 2019.
