Kardiaband is the first medical bracelet for Apple Watch approved by the FDA; Apple launches app for cardiac studies

In yet another endeavor for the wonderful combination of technology and health, the FDA (Food and Drug Administration, the body that handles food and drug regulation in the United States) has just approved the first medical accessory for the Apple Watch.

The bracelet Kardiaband was created by the medical company AliveCor, in order to provide a more accurate diagnosis for electrocardiogram (ECG) tests. The accessory was already being used in Europe, but it has only now been approved by the FDA, which allows its commercialization in the USA.

We live in a world where consumers want to know every minute what’s going on [em seus corpos] and, for the first time, they may have an FDA-approved, clinical-grade medical tool.

–Vic Gundotra, CEO of AliveCor.


The bracelet for Apple Watch Kardiaband has a metallic sensor to communicate with the company’s application and can perform electrocardiogram tests, being able to identify when the user has an abnormal heart rhythm or atrial fibrillation (AF).

In the Apple Watch app, you need to start reading and stay for 30 seconds with your thumb over the sensor and wait for completion. During this time, the user can speak into the watch’s microphone in order to also observe the presence of palpitations or shortness of breath – or even eating habits that may be linked to heart rate dissonances.

The recordings are stored and can be viewed in the iPhone app and, if necessary, shared with the person’s doctor. In addition, the data is also sent to the Health app.

The AliveCor app for Apple Watch uses the heart rate sensor present in Apple watches to take readings every five seconds. This feature was only possible thanks to the machine learning of the wearable, says Gundotra.

We were able to run a deep neural network on the Apple Watch and keep it running for 14 hours on the battery of the new Watch Series 3. Apple deserves congratulations on creating a platform that allowed us to do that – I mean, I think we have the most advanced application ever made for the Apple Watch.

Kardiaband can be purchased directly on the official website for $ 200 and, in addition, the company also has the KardiaMobile device, which can be placed on the back of iPhones for reading, which sells for $ 100.

Speaking of heart rate monitoring, Apple itself has just made a specific application available for studies in this area, the Apple Heart Study.

Sorry, app not found.

The studies will be organized in partnership with the Stanford University School of Medicine and, through the application, Apple Watch owners will be able to participate in cardiac studies to help collect data on irregular cardiac rhythms – in addition to being able to notify users that they can having atrial fibrillation (AFib).

If the user is notified by the app about any irregularity in their beats, they can receive a free consultation, by video, on their iPhone, to be performed by a medical professional in the study.

Jeff Williams, Apple COO, told us a little about the subject:

Every week, we receive incredible reports from customers about how the Apple Watch has affected their lives, including when they discovered they suffer from AFib. These stories inspire us and we are determined to do more to help people understand their health. Working alongside the medical community, we can not only inform people about certain health conditions, but we also hope to advance the discoveries of heart science.

The app is only available in the United States, for users who are 22 years or older, using an Apple Watch Series 1, 2 or 3.
