Cardiogram’s mission is to empower people to become more informed about their health data. Given the concerns about COVID-19 and increased awareness of ways to reduce the spread of flu-like infections, we want to share how and why heart rate monitoring — alongside standard methods — may be an additional tool to monitor your body’s response to an infection.A front-row …

4 Ways to Debug your Deep Neural Network

cardiogram Network

So you’ve spent weeks building a dataset and coding up a neural network. You’ve trained the model, and are getting less-than-stellar results. What do you do next? Deep learning is often seen as a black box, and I’m not going to argue with this view — what sense can you make of tens of thousands of learned parameters? But the …

Screening with wearables—what do the clinical guidelines support?

cardiogram Wearables

Consumer wearables and traditional healthcare are on a collision course. The 170+ million wearables sold per year dwarf the scale of traditional medical devices, and they come with increasingly powerful health sensors. Multiple studies have now shown accurate detection of several health conditions using consumer wearables like Apple Watch, Garmin, and WearOS by Google paired with AI-based algorithms: Atrial fibrillation: …

1 in 4 Americans now own a wearable. While it’s often assumed that those who purchase a wearable consist of the “worried well,” the data says otherwise—among Cardiogram users, the average Apple Watch owner is now 41 years old, and more likely than the general population to manage a chronic condition. Today, we’re releasing our first Wearable Healthcare Usage Report, …

Detecting Atrial Fibrillation with the Apple Watch: Our Clinically Validated Results

cardiogram Features, Watch

Your heart says a lot about you. Workouts, nights of restful and restless sleep, and stress each have distinct heart rate signatures. 1 in 4 Americans now owns a wearable device. At Cardiogram, we’re using this abundance of data to screen for cardiovascular diseases. Today, in collaboration with our research partners at UC San Francisco (UCSF), we released the first …

Screening for Hypertension and Sleep Apnea with DeepHeart

cardiogram Heart Health, Sleep

When we talk about artificial intelligence in medicine, we often debate whether machines will replace tasks doctors do today. A more tantalizing possibility is performing tasks doctors can’t—using large data sets, and modern computational tools like deep learning, to recognize patterns too subtle for any human to discern. Today, we’re presenting early clinical results showing Cardiogram’s deep neural network, DeepHeart, …
