Apple Watch Series 4 provides ECG and health capabilities

Apple has introduced Apple Watch Series 4 with watchOS 5 brings advanced communications features, along with revolutionary health capabilities that can take an electrocardiogram (ECG) using the new ECG app.

Jeff Williams, Apple’s chief operating officer said, “The completely redesigned Apple Watch Series 4 continues to be an indispensable communication and fitness companion, and now with the addition of groundbreaking features, like fall detection and the first-ever ECG app offered directly to consumers, it also becomes an intelligent guardian for your health.”

Beginning September 14, Apple Watch Series 4 (GPS) will be available to order in 26 countries and territories and Apple Watch Series 4 (GPS + Cellular) will be available to order in 16 countries and territories. Both models will be available in stores beginning September 21.

Apple Watch Series 4 is offered in two sizes, 40 mm and 44 mm. The speaker is 50 percent louder, optimized for phone calls, Siri and Walkie-Talkie. The device includes the next-generation S4 chip with a custom 64-bit dual-core processor, delivering twice the speed while maintaining the same all-day battery life.

The user interface is optimized for the larger display, allowing for app icons and fonts that are bigger and easier to read, while complications have been beautifully enhanced to be more precise and informative.

Apple Watch Series 4 enables customers to take an ECG reading right from the wrist using the new ECG app, which takes advantage of the electrodes built into the Digital Crown and new electrical heart rate sensor in the back crystal. With the app, users touch the Digital Crown and after 30 seconds, receive a heart rhythm classification.

It can classify if the heart is beating in a normal pattern or whether there are signs of Atrial Fibrillation (AFib), a heart condition that could lead to major health complications. All recordings, their associated classifications and any noted symptoms are stored in the Health app in a PDF that can be shared with physicians.

Fall detection utilizes a next-generation accelerometer and gyroscope, which measures up to 32 g-forces, along with custom algorithms to identify when hard falls occur. By analyzing wrist trajectory and impact acceleration, Apple Watch sends the user an alert after a fall, which can be dismissed or used to initiate a call to emergency services. If Apple Watch senses immobility for 60 seconds after the notification, it will automatically call emergency services and send a message along with location to emergency contacts.

Customers can reach their friends with just a tap of the wrist with Walkie-Talkie, a watch-to-watch connection that is an entirely new way to communicate around the world over Wi-Fi or cellular.

Apple Watch Series 4 (GPS) starts at $399 and Apple Watch Series 4 (GPS + Cellular) starts at $499, both featuring the updated design and new health features.

Apple Watch Series 4 comes in three aluminum finishes, anodized in silver, gold and space gray. Apple Watch Series 4 now comes in a gorgeous new gold stainless steel with matching Milanese band. Apple Watch Nike+ will feature redesigned Nike watch faces and matching bands.
