3 Reasons Not to Install watchOS 5.3.2 & 9 Reasons You Should

Install for Apple Watch Heart Features

If you have the Apple Watch 4, the watchOS 5.1.2 update unlocked one of the features you paid for when you bought the Apple Watch in several countries. With watchOS 5.2.1 and now watchOS 5.3 it arrives in Singapore, Canada, Croatia, Czech Republic, Iceland, Poland, and Slovakia. This update also includes irregular heart rhythm detection to these same countries.

With this upgrade, you will be able to use the ECG feature to take a closer look at your heart health. This can alert you to issues like AFib and other irregular heartbeat issues. This can alert you to the problem and provide valuable data to your doctor. 

The ECG app is available on your iPhone running iOS 12.1.1 or later. This update comes with FDA approval as an over the counter solution to tracking these issues. 

Untreated, AFib can lead to stroke. It is estimated that AFib is a problem for up to 2% of the young population and 9% of people over 65 years old. 

With the Apple Watch Series 1 and later, you can also get an alert for an irregular heartbeat without the need for the ECG, which can also help with heart health.
