As we think back to the Series 0 Apple Watch, released in 2015, it’s tough to believe how far the Apple Watch has come in just a few short years. The Series 4 Apple Watch was released a few months back, and by all measures, it’s the best Apple Watch ever released!
For Apple Watch Series 4 customers, the update unlocks the promised ECG app that captures a live electrocardiogram using the Watch heart rate sensor and Digital Crown. The ECG app can indicate whether your heart rhythm shows signs of atrial fibrillation (AFib) — a serious form of irregular heart rhythm, or sinus rhythm – which means your heart is beating in a normal pattern.
What It’s All About.
Each beat of the heart sends out an electrical impulse. Electrodes built into the Digital Crown and the back crystal work together with the ECG app to read your heart’s electrical signals. Simply touch the Digital Crown to generate an ECG waveform in just 30 seconds. The resulting ECG waveform- automatically stored in the Health app on your iPhone. You can share them with your doctor and have a better-informed conversation about your health.
Apple started with a pre-clinical study of 2,000 subjects, including 15 % who have been diagnosed with heart arrhythmia. 600 subjects involved with the clinical trial to validate the AFib. The company has also employed a number of medical doctors to help ensure the product meets the desired standards one would hope from a product like this.
The Apple Watch saved a life!
When you think about the Apple Watch, you also have to think about the iPhone. Without the iPhone, the Apple Watch is useless. Although the LTE model allows you to use it without being near an iPhone. You still can’t set up an Apple Watch without it. That fact makes it an iPhone accessory. It likely makes it the most profitable accessory for any consumer electronic product of all time.
Firstly, a post on Reddit talks about a user who received an abnormal reading. Atrial fibrillation, soon after his Apple Watch Series 4 updated to the latest firmware, WatchOS 5.1.2. While he initially tested the app, frequent readings coupled with normal readings when his wife tried it out led him to take the abnormal reading seriously.
Upon having it investigated properly at a medical center, he was told that the watch had likely saved his life by alerting him to an on-going cardiac issue. The patient says they proceeded to go to a cardiologist the next day, who did an exam and confirmed the AFib diagnosis.
If Apple continues to move in the direction it’s heading, and at the pace it’s heading, the Apple Watch may become to your health what the iPhone was to communication.
