Экг

Ужасно стало работать. Раньше с первого раза снимали. Теперь за 30 мин ни одной записи не удаётся сделать. Снимает пару секунд и начинает заново. Это кошмар какой-то.

Not actually available

Recently my Apple Watch series 6 removed the ECG (EKG) and Blood oxygen apps from the watch. They are searchable, but not downloadable. They are there, but cannot be used. Absolutely useless tech. Apple is having issues and they need to get on it. The EKG and blood oxygen were one of the huge selling points and without them, not really needing to upgrade past a series 3.

Great

Works as expected

Presión ante la COFEPRIS

A pesar de que el dispositivo es muy bueno es increíble que la burocracia estúpida de COFEPRIS no permita la liberación de la app ECG en mexico CUANDO CUANDO PODRÁN LIBERARLO

PÉSIMO

Estoy a punto de cambiarme de ecosistema por las limitaciones que da apple en Mexico, en países que ni sabia que existen esta disponible la app ECG, excepto en Mexico.

FAQ

What is ECG and what does it do?

The ECG app on Apple Watch Series 4 or later can take an ECG similar to a single-lead electrocardiogram. It records your heartbeat and rhythm to check for signs of atrial fibrillation (AFib) or sinus rhythm.

When should I use the ECG app?

You can take an ECG at any time, especially when you're feeling symptoms like a rapid or skipped heartbeat, or if you receive an irregular rhythm notification from your Apple Watch.

Can the ECG app diagnose AFib?

The ECG app can indicate whether your heart rhythm shows signs of atrial fibrillation or sinus rhythm. It is not a substitute for a medical diagnosis and results should be shared with your doctor.

How can I share my ECG results?

The app saves your ECG waveform, classification, and any noted symptoms as a PDF in the Health app on your iPhone. You can then easily share this PDF with your doctor.

What Apple Watch models support the ECG app?

The ECG app is available on Apple Watch Series 4 or later. It is not supported by Apple Watch SE and may not be available in all regions.

Is the ECG app free to use?

Yes, the ECG app is free to download and use. It does not have any in-app purchases or advertisements.

How often is the ECG app updated?

The latest version of the ECG app is 1.4, and it was last updated on December 12, 2025. Updates typically include performance improvements and bug fixes.

What is the age rating for the ECG app?

The ECG app has an age rating of 17+. This is likely due to the sensitive nature of health data and the potential for misinterpretation of results without professional medical guidance.
