It can detect certain cardiac arrhythmias, particularly atrial fibrillation. In principle, a great deal of people that have cardiac arrhythmias may be helped with such technology. Erratic events can be spotted, recorded and analyzed. The fourth-generation Apple Watch has been refined, combining new hardware and software enhancements into a genuinely singular, unified form. It is over 30 percent larger and seamlessly integrates into the thinner, smaller case, while the new interface provides more information with richer detail. It brings advanced activity and communications features, along with revolutionary health capabilities, including a new accelerometer and gyroscope, which are able to detect hard falls. The speaker is 50 percent louder, optimized for phone calls, Siri and Walkie-Talkie, and the microphone has been relocated, to reduce echo for better sound quality.
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. “We’re thrilled Apple Watch has become an essential part of people’s lives,” said Jeff Williams, Apple’s chief operating officer.
