If you own one of the newer Apple Watches, the Series 4, it has this dormant feature that was flipped on last year. This watch can now perform an electrocardiogram test, or EKG. It measures the electrical signals that your heart uses toregulate your heartbeat. The point is to detect signsof atrial fibrillation, which is a form of irregular heartbeat that could cause astroke or heart failure. This is actually a big step for Apple. http://tech

You might think of this watchas a notification machine for fitness buffs whowant to obsessively track every single step that they take, but with EKG, it’s trying tobecome something different. Not just a fitness tracker,but now a health monitor, but that change, it opensup a host of new questions. – Do doctors think it’s a good idea. https://worldgraphics20.com/2020/10/26/digital-and-technology-trends-in-wedding-entertainment-2020/

Are people gonna use this the right way? Are we just giving peopleall this information that they don’t even understand? – Oh, we asked our science reporter Angela to tackle those bigscary questions for us. – Hey Deeder. – And later, we’re going to fire up a more professional EKG at a medical lab, but before all that, here’swhat this new EKG feature actually looks like.

The EKG process itself is pretty simple. There are two sensors on the watch, one on the back and one on the crown. When you put your finger on the crown, you’re completing acircuit from your finger to your heart and back to your wrist. That way, the watch can measure your heart’s electrical pulses. After 30 seconds, it’lltell you if the upper or lower chambers of yourheart are out of sync and if they are, it’stime to go see a doctor. In my case, I’m seeing a sinus rhythm and that should mean no AFib.

but I’m gonna go see a doctor anyway. (soft music) We’re here at the Universityof California San Francisco to get an expert opinion. See, there’s already beena little bit of blow back about this new EKG feature. Some critics have argued that it could lead to false positives orbecome a self diagnosis machine, so we’re here to do what we expect a lot of Apple Watch owners are gonna do which is go ask a doctorabout their results. Dr. Greg Marcus is a specialist in heart arrhythmias at USFS. First, he and medicalassistant Vanessa Mallet hooked me up to a lab grade EKG.

It provides 12 differentreadings of heart activity instead of just the single snapshot that you get on an Apple Watch. – And it’s just already going. You have what’s called a sinus arrhythmia, which is a sign of good health. – [Man] Dr. Marcus walked us through some of the differencesbetween the Apple Watch EKG and this one. Basically, this thing willgive you lots more data to help pinpoint issuesthat you might suspect based on the watch’s readout.

It’s meant to be a two step process. The watch flags a possible problem and the doctor investigates further. – So if there’s an early beat for example, the 12 lead EKG willgive us more information as to exactly where that’s coming from. How that two stepprocess will work in practice? It’s not clear yet.

The feature is too new. Right now Dr. Marcus isn’t really sure what to make of it. – We still don’t know yet how frequently that Apple Watch byitself will be sufficient versus how often physicianswill not be able, not feel confident in that reading and feel that some additional monitoring needs to be done. As a researcher, it’s fascinating and a great opportunity.

As a clinician, it’s worrisome. – The worrisome thing, theprecision of the Apple Watch is only part of the story. In theory, the benefit of the Apple Watch is that it’ll catch theselurking heart problems that you would otherwise never know about. But in fact, cardiologistsdon’t recommend using it to screen for heart problemunless you’re already at risk.

Dr. Landefeld is amember of the US Preventive Services task force. They evaluate various screening tests to see if the benefits outweigh the risks. Recently, they lookedat whether EKG screening would help in people who are healthy and otherwise at low risk. They looked at it forcardiovascular disease, bad stuff like heart attack or stroke.

There’s no evidencethere that the benefits outweigh the harms and so therefore we recommended against using ECG screening for people at low risk forcardiovascular disease. – And for AFib, the conditionApple Watch screens for, similar situation. There’s just not much evidencethat EKGs are worth it if you don’t alreadyhave these other symptoms but why not just do it anyway to be safe? Because there’s a riskof a false positive.

EKG itself is safe, but in anabsolute worst case scenario, there could be a falsepositive that leads to a treatment that’s unnecessary and unsafe. – Well if it led to furthertests that somebody said, jee, it looks like you shouldundergo bypass surgery and somebody underwent bypass surgery, we know that the averagemortality from bypass surgery is one or two percent. – There’s also the issue of the users.

AFib studies focus on people 65 and older because they’re thepeople who are most likely to have heart problems. They’re not the people mostlikely to have Apple Watches, which makes Dr. Marcus worried that now all the wrong people have their own EKGs.

The individuals that tend topurchase these Apple Watches may be those who arealready health conscious, tend to be fit, tend toprobably be quite healthy, whereas the people that really probably have the most to benefit fromatrial fibrillation screening will tend to be the older individuals who may be less tech savvy, those who aren’t asconcerned about their health.

All this means that EKG might be harming all these low riskpeople with all this data that might lead them to self diagnose and get freaked out for no good reason. For them, all this might start with an irregular heartbeat alert. – They check their EKG,they don’t actually have atrial fibrillation, theyhave an irregular rhythm for some other reasonthat’s totally benign.

In reality, they’re totally okay, but now they’ve gottenthe scary notification that something might bewrong and they feel nervous. – They make an appointment with me, spend time with me and our nurses who otherwise could be helping people that clearly need help.

Again, the Apple Watch is new, but overtime, false flags put at strain to our entire healthcare system. It’s a classic case of data overload. – So with all of that in mind, what should a healthyperson use this feature for? According to Dr. Marcus, maybe nothing. If someone is younger than age 65, they don’t have highblood pressure, diabetes, they’ve never had a stroke, they don’t have heart failure, they don’t have otherproblems with their arteries. In general, I would say ignore it in the absence of symptoms.

In the end, there’s one thing that all doctors can agree on. If you’re concernedabout your heart health, be good to your heart. Don’t smoke, get plenty of exercise, and keep an eye on your blood pressure. You don’t need an EKGfeature on your Apple Watch to do any of that and yourdoctor will love you for it. – See how your rhythmspeeds up a little bit and then it slows down? People who have more ofthis sort of variability tend to live longer. – Oh really? Okay, well great.

apple watch series 5 review: the best smartwatch

apple watch series 5 review: the best smartwatch

Here it is. It’s the new Apple Watch Series 5. It’s– you know what, it’s great. I’ve used a lot of different smartwatches in my life, and this one is the best. If you have an iPhone and you can afford the$399 starting price, there is nothing better. So, like, I know.

I gave away the whole reviewat the top of the video. But keep watching becauseI do want to tell you what’s new in the Series 5 and also what’s new in watchOS 6, but I also want to seeif we can just figure out why no other smartwatch is even close to catching up to this.

All right. So, what isnew with the Series 5, at least, compared to theSeries 4 from last year? Honestly, it’s not that much,just three things, really. Okay, well, four if youcount that Apple’s offering more material options for the casing. You can get it in aluminum,steel, titanium, and ceramic. This one is aluminum, and physically, it’s identical to the Series4, which was already great.

They have larger screens than the older models of the Apple Watch, and the screen is the second thing that’s really new with the Series 5. It’s always on. Finally. See, both the Series 5,and actually the Series 4, have a special kind of OLEDscreen that Apple developed. It’s a low temperature,polycrystalline oxide, or LTPO for short. What does that mean? Well, it means, like, pixel and screen stuff like electron mobility.

What really matters is that the Series 5 has a bunch of other chips that let it have a variablescreen refresh rate, so the Series 5 can changethe pixels on the screen as often as 60 times a second or as little as once per second. That lets this use radicallyless power than other screens. You know, your watch doesn’t need to be refreshing that often when it’s just sittingthere in ambient mode, and that saves battery life.

So now, instead of thescreen just being off, it shows a dimmed versionof your watch face, and it actually even still has some color, which other smartwatches don’t do. And the, of course, whenyou raise your wrist up, it goes ooh, full color, justlike any other Apple Watch. But all this means isyou can check the time without being, you know, that jerk who obviously looks at his watch in the middle of aconversation with somebody.

Now, the big question isdoes that always-on screen hurt the battery life? And my answer is that itdoesn’t seem to hurt much. Apple claims that this still gets the same 18 hours of battery life that every Apple Watch is supposed to get. And it does for me, evenwith kind of heavy usage. But it doesn’t get much more than that.

Last year, Series 4 actually outperformed that 18-hour claim. Bottom line, you should plan on charging the Apple Watch every day. And yes, I know thatthere are smartwatches that last weeks or even months, but none of them can dowhat the Apple Watch can.

The third new thing is a built-in compass, and it works well and even gives you this neat thing called a confidence cone that gets narrower as itbecomes more confident in where north is exactly. Now, if you have a magnetic watch band, that can mess with it abit, but, you know, magnets.

That’s how they work. The fourth new thing is thatthere are more cellular bands on the cellular version,which means that it can do emergency calling internationally. Now, you should know that doesn’t mean that it’ll work for regular cell phone Apple Watch stuff, though.

Apple still needs to makecarrier deals for that to work. So, new materials,always-on screen, compass, and international emergency calling. All in all, that’s a reallyminor update, but you know what? It doesn’t matter because the Apple Watch is so far ahead of the competition. I think there’s a few reasons for that. One is the processor.

Apple is just way betterat making processors for smartwatches than anybody else. Another is integration. Apple lets the Apple Watch do Apple stuff with the Apple iPhone thatit won’t let other companies like Fitbit or Wear OS orSamsung or Withings do, like replying to iMessages. Only the Apple Watch can do that. But also, watchOS is just really good.

The new version here is watchOS 6, and it’s gonna land on every Apple Watch except the very, very first one. Now, inside this, there arenew watch faces, as usual. I like that you can set more of them to just be a single color. I do wish that therewere more watch faces, or, really, that therewere third-party options. I could get a prettygood face on this watch, but I can’t get theperfect watch face for me.

The biggest new feature inwatchOS is the App Store, which lets you installapps without having to, you know, pull out your phone,except for the first time that you use the AppStore on the Apple Watch, where you have to enteryour password on your phone.

And then sometimes, you installapps on the Apple Watch, and it needs its, like,parent app on the phone in order to work for the first time. It’s not completely independentyet, is what I’m saying. Now, it is nice to be ableto install an app in a pinch directly on your watch, I guess, but this big-deal feature isnot really a big deal to me.

Maybe when the Apple Watch gets a little bit more independent from the iPhone, it’ll matter more. Then there’s the cycles app, which lets you log andtrack menstrual activity. Now, this app isn’t for me, but I will say that I wishApple had paid more attention to women’s health sooner. Still, though, talking to people at Apple, it’s clear that they putsome care into this app. It’s scientifically cautious, and it’s thoughtful in its design.

So, it could help you track information that could be useful foryou or for your doctor. But look, fertility canbe a really hard thing, so if you’re using it with kids in mind, you should talk to yourdoctor before doing anything with the information that it provides. Let’s see. What else? Siri. Siri is here, andit can identify songs. It can also bring upsearch results from the web and lets you click into the webpages.

And my favorite thingever with the Apple Watch is still that you can load little tiny, itty bitty webpages on it. It’s kind of fun. Oh, one other thing. There is an option for the watch to detect ambient noise levels and warn you if it’s too loud for safety over a long period of time, plus I just like watching thenoise meter go up and down.

It proves to me that thetrain that I ride every day is too damn loud. The main thing that’s missingfor me is sleep tracking, which for me and my healthis much more important than closing a standing ring or whatever. There are third-part apps, though. I use Sleep++, but it seemslike a pretty obvious thing for Apple to add next year.

Okay, so, why is theApple Watch so far ahead? It’s not that it has anLTPO screen or a noise meter or really any one of the features that I just mentioned in this review. It’s the fact that I’m talking about features in this way at all. With every other smartwatch, and I’m not talking aboutthe Garmin, Wilderness, Hiking, Sporting,Mountaineering, whatever watches. I mean, like, wrist computers.

With those things, I usually have to check whether it can last more than 12 hours or whether it can open appsin less than 10 seconds or respond to a text message or if the software is buggy as hell. All that stuff was actually pretty bad in the very first Apple Watch, but it quickly got turned around, so now, Apple gets to work on filling out more advanced features.

It’s like the AppleWatch is in high school and is taking AP courseswhile everybody else is repeating the seventh grade for the third time. Sure, the Apple Watch hasn’treached anything close to its full potential yet, but right now, this thing is an overachiever. Ah, that’s still going Ah, can’t take the watch to it.
