4 Best Electrocardiogram Watches 2026 in the United States

The Apple Watch Series 9 is a robust choice for those seeking a comprehensive electrocardiogram (ECG) smartwatch. It offers advanced ECG capabilities, allowing you to take an ECG anytime and receive notifications for irregular heart rhythms, which is a critical feature for heart health monitoring. The battery life is decent, but daily charging may be required, which could be a drawback for some users. Compatibility is seamless with Apple devices, particularly those running the latest iOS, enhancing the user experience.

The watch boasts an impressive water resistance of up to 50 meters, making it suitable for swimming and other water-based activities. Additional health features like sleep tracking, temperature sensing, and emotional awareness tools provide a holistic approach to health monitoring. Ease of use is elevated by the S9 chip, offering a bright display and touchless interaction, which could be particularly appealing for those who prefer intuitive controls.

The design and comfort of the Starlight Aluminum Case with Starlight Sport Band are both stylish and durable, with customizable watch faces and bands catering to personal preferences. However, potential users should note the watch's reliance on an iPhone (XS or later) for full functionality, which might limit its appeal for non-iPhone users. Despite the high level of durability, the heavier weight (10.2 ounces) might be a consideration for those who prefer lighter wearables. In essence, the Apple Watch Series 9 excels in providing a blend of health tracking, fitness features, and smart connectivity, but it may not be the best fit for individuals outside the Apple ecosystem or those seeking longer battery life.

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.

The SAMSUNG Galaxy Watch 4 Classic 46mm is a robust smartwatch that excels in ECG monitoring, allowing users to accurately track heart health and share readings with their doctor using the Samsung Health Monitor app, which requires a compatible Galaxy phone. The watch also offers comprehensive body composition analysis, advanced sleep tracking, and automatic workout recognition for six popular activities, making it ideal for fitness enthusiasts. The built-in GPS and ability to receive VO2 Max readings enhance its usefulness for runners and outdoor adventurers.

Moreover, it integrates seamlessly with Google services and apps, providing convenience for tasks like payments and navigation directly from the wrist. With a large 46mm screen and comfortable design, it is stylish and user-friendly. However, its reliance on compatibility with Galaxy phones might limit its appeal to non-Samsung users. The battery life, being dependent on usage, might require frequent charging, especially with active use of GPS and health monitoring features.

Additionally, while it offers water resistance, it's not suitable for deep-water activities. Those looking for a versatile smartwatch with a strong focus on health and fitness tracking will find the Galaxy Watch 4 Classic a great option, but potential buyers should consider their phone compatibility and charging habits.
