When evaluating which Apple Watch does EKG, it is important to understand that this specific health functionality is not available on every model. The ability to perform an electrocardiogram is a regulated medical feature that depends on both hardware sensors and software clearances in different regions. This distinction is crucial for consumers who prioritize heart health monitoring as a primary factor in their wearable technology purchase.
Understanding EKG Availability on Apple Watch Models
The core requirement for EKG functionality is the presence of specific electrical sensors built into the back crystal of the device. Simply having a modern Apple Watch is not enough; the hardware must be designed to channel the electrical signal from your finger through the crown and into the electrodes. Without this physical infrastructure, the software cannot generate the reading, regardless of how new the watch is. Therefore, checking the specific technical specifications is the first step in determining compatibility.
Current Models That Support the Feature
As of the latest software iterations, the following Apple Watch models are compatible with the EKG app: the Series 4, Series 5, Series 6, Series 7, Series 8, and the second-generation Apple Watch SE. These models contain the necessary hardware architecture to capture the electrical signals of the heart. If you are looking to use this feature, choosing one of these models is essential, as older versions like the Series 3 or the original SE do not possess the required sensors.
Regional Restrictions and Legal Clearances
Even if you own a compatible model, the availability of the EKG feature can vary significantly based on your geographic location. In the United States, the feature is available through a software download after updating to the latest version of watchOS. However, in the European Union and certain other regions, the regulatory approval process required specific modifications to the app's workflow. Consequently, users in these regions will see a different interface that guides them to the Irregular Rhythm Notification feature instead of the full doctor-grade EKG scan.
Software Requirements and Setup
To ensure which Apple Watch does EKG, you must also confirm that your watch is running the latest software version. The EKG app is distributed via the App Store on the watch itself, and it requires a recent version of watchOS to function correctly. If the app is not visible in your available apps list, you should navigate to the Watch app on your iPhone, tap on "My Watch," and check for updates under the "Available Apps" section. Installing the update is usually straightforward and only requires a few minutes connected to Wi-Fi.
