4 Best Electrocardiogram Watches 2026 in the United States

The Fitbit Sense 2 is a well-rounded health smartwatch that suits users looking for advanced heart monitoring alongside general fitness tracking. Its ECG app offers atrial fibrillation detection and irregular heart rhythm notifications, making it a useful tool for heart health awareness, though it is not a replacement for professional medical devices. Battery life is solid, lasting over six days in typical use, which means less frequent charging compared to many other smartwatches. It pairs easily with Android devices and supports Bluetooth connectivity, but Apple users might miss deeper integration found in Apple Watches. Water resistance up to 50 meters means it’s safe for swimming and showering, adding to its versatility.

Beyond ECG, it tracks blood oxygen levels, stress through cEDA, sleep stages, and offers mindfulness tools, providing a broad picture of your wellness. The built-in GPS and 40+ exercise modes make it handy for fitness enthusiasts who want detailed activity insights. The design is slim and comfortable, with options for different wrist sizes, and the raised band attachments improve wearability for all-day use. On the downside, some users might find the screen a bit small at 1.58 inches, which could affect readability, and the ECG feature requires user initiation rather than continuous monitoring. Also, advanced features like Google Health Premium come only with a limited trial, which may require a subscription to continue.

In conclusion, the Fitbit Sense 2 represents a strong choice for those seeking a multi-functional health smartwatch with reliable ECG capabilities and good battery life, especially if you use Android and want a comfortable, stylish wearable.

The Fitbit Sense is a well-rounded health and fitness smartwatch that includes ECG functionality to monitor heart health, along with stress sensing and skin temperature tracking. Its ECG accuracy is generally reliable for a consumer device, helping detect irregular heart rhythms. Battery life is strong, offering around 6 days on a single charge, which is convenient for continuous health tracking without frequent recharging. The watch works smoothly with both iOS (12.2 or higher) and Android (7.0 or higher) devices, ensuring wide compatibility.

It is water-resistant up to 50 meters, making it suitable for swimming and daily wear without worry. Beyond ECG, it tracks heart rate, blood oxygen levels (SpO2), and stress, giving a broader picture of your health. The built-in GPS adds value for those interested in outdoor activities like running or walking. Design-wise, the Fitbit Sense is lightweight and comfortable, with a 1.59-inch OLED touchscreen that is easy to navigate even for beginners. Notifications and call/text replies from the wrist add practical convenience.

One drawback is that the international version does not include a US warranty, which might concern some buyers. Also, while the watch covers many health metrics, it may not replace professional medical-grade ECG devices. The Fitbit Sense provides a strong balance of health features, ease of use, and comfort, making it a good choice for users wanting to monitor heart health along with general fitness.

The KardiaMobile Card Wallet-Sized Personal EKG Device is an excellent option for those needing a portable, easy-to-use electrocardiogram (EKG) monitor. One of its standout features is its compact design; it is as thin and light as a credit card, making it extremely convenient to carry around in your wallet.

The device is FDA-cleared and recommended by doctors, providing accurate medical-grade EKG results quickly. Users can easily record their heart rhythm by placing their thumbs or fingers on the sensors, and it can detect a range of conditions including Atrial Fibrillation, Bradycardia, Tachycardia, and Normal Sinus Rhythm without requiring a subscription. For those who desire additional detections and features, a KardiaCare subscription is available but not mandatory.

The KardiaMobile Card connects to your smartphone via Bluetooth, eliminating the need for WiFi and ensuring that you can take an EKG anywhere, anytime. It is compatible with most smartphones and tablets, but it is advisable to check the compatibility list on the AliveCor website. While it offers a good range of heart monitoring features, those looking for comprehensive health tracking might find it limited without the KardiaCare subscription. The device is made of plastic, which might not appeal to those looking for a more premium feel. However, its lightweight build and ease of use make it a strong choice for anyone needing reliable heart monitoring on the go.
