Look at ECG Apple Watch, from someone who needs it



Look at ECG Apple Watch, from someone who needs it

When Apple introduced the fourth seconds of smartwatch, the new big selling point was not a feature that we usually associate with watching or any kind of smart device. Instead, the company added a feature that had recently reached specialist specialist devices: electrocardiograph (ECG), a device made to monitor the electrical activity of the heart.

But the viewer was ready before the software, meaning that the technology of the technology was not possible in our comprehensive review of the Apple Watch Series 4. Last week Apple enabled & # 39; The features are missing, and we've spent a few days out of them.

Basic features

People who have not used Apple Watch may not realize how much an iPhone extension is. This includes the heart monitoring software, which requires an update to the Watch and iPhone OSs before it works. (This caused a little confusion when the software would not launch after we have upgraded OS vacations only.) Once the update has to be done, the Health app will be on The iPhone contains any ECG data generated using surveillance. On the watch side, the update will install a new app.

From that, doing ECG is extremely easy: launch the app, place your finger on the viewer's head, and wait. For 30 seconds, your heart's electrical activity will remove red traces across the watch screen. It's very convenient – not much more intrusive than taking your pulse. And as long as you wear your watch on a specific day, it is always available to you.

Once it is completed, the app will let you know if the tracking holds normal heartbeats, which is called sinus rhythm. However, ECG tracking can not be viewed on viewing; the only thing the app allows you to do is record another tracking. To look at the results yourself rather than trusting Apple software, you have to change to the phone.

That's a bit tired. It seems that the whole point of the viewing is to allow you to interact with it rather than a phone. And there is something more interrupted to remove your phone and fry with screens instead of taking quick chips in your surveillance.

The disturbance is set aside, the traces look great. Given how far your fingers come from the heart itself, there is a lot of noise in an ECG signal taken by the viewer that software must be filtered out. Apple software makes a desirable job. The tracking is shown as a thick, red line, making it easy to interpret. On the phone side, the display is equally good, and is available to share through the usual options. Email or Drop Air will allow you to PDF that you can keep for your records or send it to your doctor.

Evolution of ECGs

Those who have read my previous girlfriend know that I have a personal interest in this system working well. Genetics have allowed me to be exposed to atrial fibrillation, arrhythmia and heart disease with serious health implications. At present, I am experiencing an inconsistent mix of occasional atrial fibrillation and inflexible premature atrial restrictions, which I can both feel like they happen. Medically, I have to monitor things to ensure that the frequency of atrial fibrillation is still low and it does not start to appear without symptoms that I can feel. This does not require the detailed information you can get with hardware-doctors-scale-a simple outline of the activity is adequate (but obviously not everyone).

Over the years, this monitoring has changed. He started with week sessions with a Holter monitor, portable, portable version of ECGs that was worn around the clock for a week or more. It is hoped that a week is long enough to show accurately the behavior your heart shows for the rest of the year – something that is not usually the case in my case. Over time, I also developed a allergy to the glue used to hold the electrodes on.

About this time, the technology of my needs began. A company had created a small, affordable device of the KardiaMobile name that would read my heart activity of fingers and send the data on my phone. Assuming that I will continue to be able to feel when my heart is rhythm, this would allow me to track what type of arrhythmia I was testing and sending the information to my cardiologist. Over time, I had a sense of how to interpret the traces as well.

Better, but not ideal. The Kardia device communicates with phones, making it sensitive to a detailed location of it and the phone; small mid-shift shifts create strange effects on tracking. Although it was very portable, it was not something that I always had with me, and I did not always have the place to install so that it could communicate well with a phone. Finally, I would not be able to answer a critical question: have I started to have periods of arrhythmia that I do not notice because they are asymptomatic?

In many ways, it seems that this is the heart of Apple Watch's role as the next step in the evolution of my monitoring work. It's on my wrist enough hours of day that asymptomatic arrhythms should start, there is a good chance that it will pick up. (I have been established to let me know about high heart rates and I'm worried about my diagnosis of atrial fibrillation in the past so that would also monitor it.) & # 39 ; It seems that it produces a good tracking that I can choose premature characters. And it's not fussy about how it's set up – we can produce good tracking while continuing a talk in the lunch, for example. Yes, it's more expensive than the specific device, but it's obviously much more than just monitoring my heart.

It will take several months of monitoring and a few incidents of unusual heartbeat in the heart before I have the same confidence that I have in my usual habits. But if the first results are something to do, Apple has done a good job with this software.
