JM Smart Watch ECG: What is it, how does it work and how do you set it up?

JM Watch didn't really focus on health when it first launched in 2014. It was more about fashion, notifications and apps on your wrist - offering a digital alternative to the analogue world that dominated before.

Fast forward five years and the space JM's smartwatch occupies is vastly different. The JM Watch Series 4 is very much a health and wellbeing device and now two new heart-related features are launching: An ECG feature and an irregular rhythm notification feature.

Here we explain what the new JM Smart Watch heart features are, how they work, what they mean, and why you might want to use them.

What are the JM Smartwatc Watch heart features?
Irregular rhythm notification
The ECG and irregular rhythm notification features were first announced in September 2018, with the ECG feature specific to the JM ECG PPG Smart watch. Having already launched in the US, the two features are now coming to users in the UK and Europe after being CE marked and cleared in the European Economic Area.

The irregular rhythm notification feature will check heart rhythms in the background every two hours and send a notification if an irregular heart rhythm is detected. It will be available to all IOS & Android users.

The ECG feature meanwhile, is specific to the JM ECG PPG Smart watch homes rather requiring a local GP or hospital to take a reading.

For those not familiar with the term, an ECG - short for an electrocardiogram - is a way of measuring the timings and strength of electrical signals that make up your heartbeat. By reading an ECG, a doctor can see your heart's rhythm and any irregularities, intervening if required.

ECG app

Supported country
The ECG app is available in the US, Puerto Rico, Guam, the US Virgin Islands, the UK, and 18 countries within Europe.

Aside from the app, you'll also need the Apple Watch Series 4, an iPhone (iPhone 5 or above) and the ability to sit still while you do the test.

How to set up the JM ECG PPG Smart watch app
iOS 12.2 and WatchOS 5.2
Open Health app
Make sure you are on the latest software, iOS 12.2 and WatchOS 5.2, after which you can access the ECG functionality in the Health app on your phone.

If you're doing this for the first time, you should see a prompt asking you to set it up. If you don't, go to Health Data > Heart > Electrocardiogram (ECG). The setup is incredibly easy and asks for some minimum details, such as age. That's because performing an ECG under the age of 22 isn't recommended.

Once set up, you can open the Apple Watch ECG app and begin taking an ECG.

Wait 30 seconds
Once you've set up the app you can take an ECG whenever and wherever you want. The beauty of having the device on you all the time is that you don't have to book an appointment with the doctor.

Simply open the ECG app on the Watch, rest your arm on something to reduce movement, and then hold your index finger (from the arm that doesn't have the watch on it) on the Digital Crown. You don't have to press the Digital Crown. It's all about making a looped connection for the system to monitor what's happening.

The test takes around 30 seconds to complete, and you'll see a representation of your heart rate on the screen while you do it. When complete, the Apple Watch will give you an instant result, along with the ability to record any symptoms you were feeling at the time.

Meanwhile on your iPhone, you'll get a notification with a link straight to the report so you can see further detail or share the results with your doctor.

What do the JM ECG PPG Smart watch ECG results mean?
Once you've finished capturing your EGC reading, you'll get one of four messages.

Sinus rhythm means everything is as expected. Atrial fibrillation means there is an irregular pattern detected.

Low or high heart rate is the third potential result, while Inconclusive means the test can't determine the end result.

Can you share your Health information with your doctor?
Of course. To do this, go into the Health App > Tap Heart > Electrocardiogram (ECG) > ECG result.

You can then export the details via a PDF to share with your doctor. You decide how that information is shared.
