Garmin ECG in Venu 3 smartwatches

Garmin has released the Garmin ECG app in Venu 3 and Venu 3S smartwatches. In October 2023, Venu 3 and Venu 3S received the product update to include the Garmin ECG app.


At the time of the launch of the Venu 3 and Venu 3S smartwatches, both smartwatches did not support the Garmin ECG app.

The smartwatches did have the next-generation optical sensor to help in taking on-the-spot electrocardiogram readings. The capability to take ECG was built in the Venu 3 and Venu 3S smartwatches.

It was a matter of enabling the support for the Garmin ECG app through an update.

ECG app on Garmin smartwatches

Garmin received FDA approval for its ECG app in January 2023. Garmin announced that it received FDA approval for the ECG app. vide a press statement about the ECG app and FDA approval.

Subsequently, the ECG app was added to the Garmin Venu 2 Plus smartwatch. Eventually, the Garmin ECG app was rolled out to the Venu 3 series smartwatches, Epix 2 Pro series, and Fenix 7 Pro series smartwatches.

We would like to add that the Garmin ECG app may not be used for diagnostic purposes. It does not in any way substitute expert medical advice for underlying heart conditions.

What does the Garmin ECG app do?

Garmin ECG app will take 30-second electrocardiograms. These electrocardiograms will record your heart rhythm and record the heartbeat. The optical heart sensor at the back of the watch is used to take spot electrocardiogram readings.

The data collected by the sensors is shared with the ECG app. The ECG app will analyze the heart rhythm and display the heart rhythm results immediately.

Alternatively, you can use the Garmin Connect app to check the heart rhythm report. However, the data in the Garmin Connect app is not made available instantaneously. There is a slight delay before the Garmin Connect app offers the analyzed heart rhythm data.

In which countries is the Garmin ECG app available?

The Garmin ECG app is available in the United States, Hong Kong, Taiwan, and Vietnam. This is as of filing this report in November 2023.

Garmin is looking to expand the ECG functionality to other devices and smartwatches within the United States. At the same time, it is striving to extend the ECG feature in multiple countries.

For now, the feature is limited to Garmin Venu 2 Plus, Venu 3, Venu 3S, Fenix 7 Pro, and Epix 2 Pro smartwatches.

Atrial Fibrillation and ECG apps

The Garmin ECG app is expected to detect conditions of irregular heart rhythm or Atrial Fibrillation. We know that Apple watches have had the ECG feature since the 4th generation Apple series watch.

Apple watches are considered very reliable in detecting health conditions of Atrial Fibrillation.

The Garmin ECG app is currently limited to the Garmin Venu 2 Plus, Venu 3, Epix 2 Pro, and Fenix 7 Pro watches only.
