Apple Watch Series 4 with industry-first features like ECG reading app and irregular rhythm notification will now be available in Europe and Hong Kong.

With watchOS 5.2, customers in 19 European countries including Germany can take an ECG reading with Apple Watch Series 4 at any time.

“All recordings, their associated classifications and any noted symptoms are stored securely in the Health app on iPhone,” Apple said in a statement late Wednesday.

The ECG app enables customers to take an electrocardiogram right from their wrist.

It can capture heart rhythm on demand in a moment when users experience symptoms such as a rapid or skipped heart beat and help provide clinically important data to physicians.

The irregular rhythm notification feature on Apple Watch occasionally checks heart rhythm in the background and sends a notification if an irregular heart rhythm that appears to be atrial fibrillation (AFib) is identified.

The ECG app and irregular rhythm notification feature can alert users to signs of AFib.

“We’ve seen the ECG app and irregular rhythm notifications on Apple Watch have meaningful impact on our customers across the US,” said Jeff Williams, Apple’s Chief Operating Officer.

A recent clinical trial of around 600 participants found that the ECG app on Apple Watch demonstrated 98.3 per cent sensitivity in classifying AFib and 99.6 per cent specificity in classifying sinus rhythm in classifiable recordings, when compared to an ECG administered by a cardiologist.

The irregular rhythm notification feature was recently studied in the Apple Heart Study which found “only 0.5 per cent of participants received irregular pulse notifications, an important finding given concerns about potential over-notification.” (IANS)

Paris police investigators think an electrical short-circuit most likely caused the fire at Notre Dame Cathedral, a police official said Thursday, as France paid a daylong tribute to the firefighters who saved the world-renowned landmark.

A judicial police official told The Associated Press that investigators made an initial assessment of the cathedral Wednesday but don’t have a green light to search Notre Dame’s charred interior because of ongoing safety hazards.

The cathedral’s fragile walls were being shored up with wooden planks, said the official, who spoke on condition of anonymity because he wasn’t authorized to speak by name about an ongoing investigation.

Investigators believe the fire was accidental, and are questioning both cathedral staff and workers who were carrying out renovations. Some 40 people had been questioned by Thursday, according to the Paris prosecutor’s office.

The police official would not comment on an unsourced report in Le Parisian newspaper that investigators are looking at whether the fire could have been linked to a computer glitch or the temporary elevators used in the renovation work, among other things. The prosecutor’s office said only that “all leads must be explored.”

Temporary structure proposed

Since the cathedral will be closed to the public for years, the rector of the Catholic parish that worships there has proposed building a temporary structure on the plaza in front of the Gothic-era landmark, and City Hall gave its approval Thursday “subject to technical restraints.”

“The rector has no cathedral for the moment. … But I’m going to try to invent something,” Bishop Patrick Chauvet said.

A crypt containing vestiges dating from antiquity is located under the vast esplanade.

President Emmanuel Macron has said he wants Notre Dame to be restored in five years, in time for the 2024 Summer Olympics, which Paris is hosting. Restoration specialists have questioned the ambitious timeline, with some saying it could take three times that long to rebuild the 850-year-old architectural treasure.

Honoring the firefighters

Earlier Thursday, Macron held a ceremony at the Elysee Palace to thank the hundreds of firefighters who battled the fast-moving fire at Notre Dame for nine hours starting Monday evening, preventing the structure’s destruction and rescuing many of the important relics held inside.

“We’ve seen before our eyes the right things perfectly organized in a few moments, with responsibility, courage, solidarity and a meticulous organization,” Macron said. “The worst has been avoided.”

The cathedral’s lead roof and its soaring spire were destroyed, but Notre Dame’s iconic bell towers, rose windows, organ and precious artworks were saved.

Macron said the firefighters will receive an Honor Medal for their courage and devotion.

Paris City Hall also held a ceremony in the firefighters’ honor Thursday afternoon, with a Bach violin concert, two giant banners strung from the monumental city headquarters and readings from Victor Hugo’s “The Hunchback of Notre Dame.”

Remarkably, no one was killed in the blaze that broke out as the cathedral was in the initial stages of a lengthy restoration.

Securing area, cathedral

A large swath of the island in the Seine River where Notre Dame is located was officially closed Thursday by police, who cited “important risks” of collapse and falling objects. The area had been unofficially blocked off since the fire.

Meanwhile, workers using a crane removed some statues to lessen the weight on the cathedral’s fragile gables, or support walls, to keep them from collapsing since they were no longer supported by the roof and its network of centuries-old timbers that were consumed by the inferno.

They also secured the support structure above one of Notre Dame’s rose windows with wooden planks.

Saving history

Among the firefighters honored Thursday was Paris fire brigade chaplain Jean-Marc Fournier, who told the Le Parisian daily he was able to save the cathedral’s consecrated hosts. The paper said he climbed on altars to remove large paintings, but that he was especially proud “to have removed Jesus” from the Cathedral — a reference to the Catholic belief that consecrated hosts are the body of Christ.

An earlier report credited Fournier with helping salvage the crown of thorns believed to have been worn by Jesus at his crucifixion, but Fournier told France Info Thursday he arrived after rescuers had already broken the relic’s protective covering and an official who had the secret code needed to unlock it finished the job. He praised the action that preserved “this extraordinary relic, this patrimony of humanity.”

Among others honored was Myriam Chudzinski, one of the first firefighters to reach the roof as the blaze raged. Loaded with gear, they climbed hundreds of steps up the cathedral’s narrow spiral staircase to the top of one of the two towers.

“We knew that the roof was burning, but we didn’t really know the intensity,” she told reporters. “It was from upstairs that you understood that it was really dramatic. It was very hot and we had to retreat, retreat. It was spreading quickly.”

Benedicte Contamin, who came to view the damaged cathedral from afar Thursday, said she’s sad but grateful it’s still there.
