It's part of Apple's long-in-the-making strategy to give people a distinct reason to buy a wrist gadget that largely does things smartphones already do.
"And the watch is unambiguously the most personal product we make", said Ive, who joined Apple more than 25 years ago and first made his mark with the candy-colored iMacs of the 1990s.
Worldwide, about 48 million smartwatches are expected to be sold this year compared to almost 1.9 billion phones, according to the research firm Gartner.
"Capturing meaningful data about a person's heart, in real time, is changing the way we practice medicine", said Benjamin, who is also director of the Cardiovascular Center at the Medical College of Wisconsin.
Apple announced a slew of new health features for its Apple Watch on Wednesday, including an FDA-cleared electrocardiogram sensor that is created to alert users to potential problems with their heart so they get to a doctor in time.
The big Apple announcement this week was clearly an iPhone or three, but it wasn't alone, because there's also a new wearable coming, too. With the upcoming annoncment of a new Apple Watch, I am wondering whether smart watches are for everyone.
"People are scared; their heart scares them", John Mandrola, a cardiologist at Baptist Health in Louisville, said.
It could also lead some health insurance plans to subsidize the cost of an Apple Watch, Nguyen said. The XS Max, the largest iPhone to date and one of the biggest on the market, has a 6.5-inch (16.5-cm) screen, and starts at $1,099 in the U.S.
Another bit of good news is that the new Series 4 will be fully compatible with older bands. "Among young and healthy populations, the prevalence of atrial fibrillation is so low that even if the Watch says they have the condition, it's unlikely that they do".
Apple's new smartwatch will have the ability to take high-quality heart readings to detect irregular heart rhythms and other potential problems. The smartwatches are able to detect hard falls, and an electrical heart rate sensor can take an electrocardiogram.
Apple said the EKG feature will be available to USA customers later this year, an indication that it may not be ready for launch.
If an irregular heart rhythm is detected, participants in the study are notified through the Apple Watch and on their iPhones and offered a free consultation with a study doctor. The watch will then wait 1 minute, and if there is no response, the watch automatically calls 911 and sends messages to the users emergency contacts.
Update: Apple is launching the Apple Watch Series 4 in India next week starting for Rs 40,990 for the Global Positioning System only 40mm variant while going all the way upto Rs 80,900 for the cellular 44mm variant with a stainless steel case and Milanese loop band.
The apps are not meant to substitute for physician visits, but can gather data that might help doctors more than simple patient reports of a fluttering heart rate or breathlessness. Apple insists that the improved accelerometer won't be tricked and can easily differentiate a fall from other awkward movements.
