Sleep tracking has become an important feature of smartwatches, with Cardiogram being at the forefront of this technology. Cardiogram's deep neural network technology, called DeepHeart, can detect hypertension and sleep disorders such as sleep apnea. Sleep apnea is a serious sleep disorder that can lead to several complications, including daytime fatigue, high blood pressure, and type 2 diabetes. By continuously monitoring heart rate data, Cardiogram's clinically-validated algorithms can detect anomalies and patterns that suggest the presence of sleep apnea, helping to improve the quality of life and overall health of the user. In addition to sleep apnea detection, Cardiogram also provides insights into sleep patterns and overall health, allowing users to make more informed decisions about their lifestyle and treatment options.

What You'll Learn
Cardiogram app: Beta testing phase
The Cardiogram app is a subscription-based service with a 30-day free trial for new users. It offers a range of features, including the ability to track sleep. However, it's important to note that the sleep-tracking feature is currently in the beta testing phase. This means that while you can use the Cardiogram app to track your sleep, the functionality may not be fully developed or optimised yet.
During the beta testing phase, users are essentially testing out the new feature and providing feedback to the developers. This feedback is invaluable as it helps identify any issues, bugs, or areas for improvement. By releasing the sleep-tracking feature in beta, Cardiogram can gather insights from real-world usage and make adjustments before the official release.
To track your sleep using Cardiogram during this beta phase, you'll need to have the app installed on your smartwatch. The app uses heart rate data from your watch to not only track sleep but also to pre-diagnose certain heart conditions, such as sleep apnea. By continuously monitoring your heart rate, Cardiogram can provide insights into your sleep patterns and overall health.
While the Cardiogram app itself can track your sleep, it is also compatible with third-party sleep tracking apps. These include "Sleep as Android", "Pillow", and "Sleep Cycle". By using one of these apps in conjunction with Google Fit, you can record your sleep data and then view it within the Cardiogram app. This provides an alternative method for tracking your sleep while the Cardiogram app is still in its beta testing phase.

Sleep data: Third-party apps
The Cardiogram app can be installed on your watch to track your sleep. However, this feature is currently in the Beta testing phase. You can also track your sleep duration using third-party apps that can write sleep data to Google Fit, which can then be read by Cardiogram.
Sleep as Android is one such third-party app. Once installed, it will write sleep data to Google Fit. You can then use Cardiogram to read the sleep data from Google Fit and display your sleep duration within the Cardiogram app.
Other apps that can be used for this purpose include Pillow and Sleep Cycle. These apps can help you track your sleep duration and patterns, and provide insights to make more informed decisions about your lifestyle and treatment options.
Additionally, if you have an Apple Watch, you can track your sleep by enabling the "Track Sleep" feature. Make sure your Apple Watch is charged to at least 30% before bed and wear it for at least one hour each night. You can then view your recent sleep data on your Apple Watch or in the Health app on your iPhone or iPad.

Sleep apnea: Detection and treatment
The Cardiogram app has the ability to track your sleep, although this feature is currently in the Beta testing phase. The app uses heart rate data from a standard smartwatch to pre-diagnose certain heart conditions, like sleep apnea. It continuously monitors your heart rate data, using algorithms that can detect anomalies and patterns that could suggest sleep apnea. This is a huge innovation, as it eliminates the need for specialized medical equipment or unnecessary sleep tests.
Sleep apnea is a serious sleep disorder in which breathing repeatedly stops and starts during sleep. The most common type is obstructive sleep apnea (OSA), which occurs when the throat muscles relax and collapse during sleep, blocking the airway. Central sleep apnea (CSA) is when the brain doesn't send signals to keep breathing-related muscles working while you sleep. Mixed or complex sleep apnea is a combination of both OSA and CSA.
There is currently no cure for all types of sleep apnea, however, there are treatments that can help manage symptoms and prevent complications. A healthcare provider can recommend treatment options based on the type and severity of the condition. These may include using a continuous positive airway pressure (CPAP) machine, managing any underlying conditions, changing your sleeping position, wearing an oral appliance, or using a neuromuscular electrical stimulation (NMES) device. Weight loss or surgical treatments may cure OSA.
It is important to catch sleep apnea early to improve quality of life and reduce the risk of associated health issues such as hypertension, stroke, heart disease, and diabetes. Follow-up visits with a healthcare provider are crucial to ensure treatments are working.

Heart rate: Continuous monitoring
Heart rate monitors are devices that track your heart rate and pulse rate. They are a very popular feature in wearable devices like smartwatches and fitness trackers. Cardiogram is one such app that can be installed on your smartwatch to track your sleep. It uses clinically-validated algorithms to monitor your heart rate continuously, giving you a full picture of your sleep patterns and overall health.
The Cardiogram app uses heart rate data from a standard smartwatch to pre-diagnose certain heart conditions, like sleep apnea. Sleep apnea is a serious sleep disorder in which breathing repeatedly stops and starts during sleep, leading to complications like daytime fatigue, high blood pressure, and type 2 diabetes. By continuously monitoring your heart rate data, Cardiogram can detect anomalies and patterns that suggest the presence of sleep apnea, helping to advance preventative medicine.
There are two main types of heart rate monitors: electrical (electrocardiography) and optical (photoplethysmography). Electrical heart rate monitors detect the small electrical current generated by each heartbeat. Optical heart rate monitors use infrared light to see the expansion of your arteries as your heart pumps blood through them. These devices can also estimate oxygen levels in the blood. Chest-band devices, a type of electrical heart rate monitor, are considered the most accurate as they measure heart rate directly.
Heart rate monitors have various benefits and uses. They can be used to track heart rate during exercise, monitor stress and activity levels, track sleep quality, and monitor vital signs at home for those with health concerns. Additionally, heart rate recovery, or how quickly your heart rate decreases after intense activity, is a useful measurement of health and fitness. While optical monitors are sufficient for most people, chest straps are recommended for those who use heart rate data seriously for fitness as they provide more accurate readings during rapid heart rate changes.
