Thanks for the shout-out! We posted a few example normal and abnormal heart rhythms from Apple Watch here: https://blog.cardiogr.am/what-do-normal-and-abnormal-heart-r... Joe: this is really cool work! Happy to chat if you&

Very cool. As you're thinking about unsupervised or semi-supervised deep learning, consider medical data sets as a potential domain. ImageNet has 1,034,908 labeled images. In a hospital setting, you'd be lucky to get 1000 particip

Thank you! That is helpful feedback.

That's part of what we're trying to quantify with the mRhythm Study--both the accuracy of heart rate sensors on average, but more importantly, how to predict in which situations and for which people the sensor is likely to work ac

Any circuit through the heart is enough for (at least a single-lead) ECG. For example, the AliveCor is a hand-held mobile phone case—when your left hand and right hand are both touching it, you can get an ECG. Chest ECGs done at the hospita

This is super cool. Someone I know is working on a platform to help startups with FDA compliance (specifically the quality systems requirements), who I think would be complementary to this effort. Mind emailing me at brandon@cardiogr.am if

Check out the CONCORD study, which compared cancer survival rates across 18 countries. The US had the highest overall survival rate (73.8%). Countries with government-run medical care, like UK and Denmark, had the lowest: 51-52.8%. The diff

Although this is an interesting result, beware, n=25 for the whole study, which means there were only eight people per group. We did a data analysis on several thousand Apple Watch users, looking at whether step count or exercise intensity

I worked on Android in 2008 and now work on applying Apple Watch to heart health ( https://cardiogr.am or http://on.wsj.com/1qCfnjR for details). People forget how long it takes a new platform to develop. It took

Our academic partner at UCSF Cardiology hosts their study on their own domain ( https://www.health-eheartstudy.org/ ). If you sign up through the links to Health eHeart provided at mRhythmStudy.org, you'll see a customiz

Yes! We plan to support other devices like Fitbit and Android Wear. My co-founder and I both worked on Android at Google, so we'd love to get back to Android Studio.

by brandonb 11y ago
We do plan to support other devices like Fitbit and Android Wear. The reason we started with Apple Watch is that 1) the heart rate sensor is quite good, and 2) we can target millions of people with one platform (iOS / Watch OS).

Oh sorry—that's confusing. You'll actually have two accounts. One for the Cardiogram app using your choice of Facebook / Twitter / Email, and one for Health eHeart study (our partners at UCSF) using email. When you sign

by brandonb 11y ago
Yeah! Absolutely. In healthcare we call it "patient compliance," but it's really just usability. My guess is that by the time we get to the Apple Watch or Android Wear 3 or 4, it'll include a built-in ECG sensor. There a

We're lucky in that information covered by HIPAA (e.g., the medical record) is handled by our academic partner at UCSF, the Health eHeart study (health-eheartstudy.org). I think it's a bit of a misconception that you always need a

If we succeed in training an accurate enough machine learning algorithm, I think the primary purpose will be to screen for asymptomatic atrial fibrillation, and then use a Holter or Zio Patch for a final diagnosis. The main benefit is that

Thank you for participating! And that's exactly what we're measuring—how accurate is the Watch, and in what circumstances does it make errors? The anecdotal evidence is very conflicting, which is why we're comparing the AW to
