## What is ECG?

ECG

With the ECG app on Apple Watch Series 4 or later*, you can take an ECG similar to a single-lead electrocardiogram. The ECG app can record your heartbeat and rhythm using the electrical heart sensor on Apple Watch and then check for signs of atrial fibrillation (AFib), a form of irregular rhythm.

Features

• Allows you to take an ECG similar to a single-lead electrocardiogram.  

• Take an ECG at any time, when you’re feeling symptoms such as a rapid or skipped heartbeat, or when you receive an irregular rhythm notification.

• The ECG app can indicate whether your heart rhythm shows signs of atrial fibrillation—a serious form of irregular heart rhythm—or sinus rhythm, which means your heart is beating in a normal pattern.

• Saves ECG waveform, classification and any noted symptoms in a PDF on the Health app on iPhone to share with your doctor.

*Not available in all regions. ECG app is not supported by Apple Watch SE.

## Key features

- Take single-lead ECG readings
- Detect signs of atrial fibrillation (AFib)
- Check for normal sinus rhythm
- Record symptoms alongside ECG
- Export ECG data as PDF
- Share results with healthcare providers

### 2/5 — Экг

*2022-04-09, version 1.1.1*

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.

### 1/5 — Not actually available

*2022-02-08, version 1.1.1*

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.

### 5/5 — Great

*2022-02-02, version 1.1.1*

Works as expected

### 4/5 — Presión ante la COFEPRIS

*2022-01-27, version 1.1.1*

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

### 1/5 — PÉSIMO

*2022-01-27, version 1.1.1*

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.

### 1/5 — ECG issues

*2022-01-23, version 1.1.1*

First off it says it’s available for my watch series and then other places it says it’s not absolve for my watch series and won’t let me download and if it only is on one type of Apple Watch it should be available on all of them for people like me who have health issues

### 1/5 — Cuando en México?

*2022-01-14, version 1.1.1*

Cuando estará disponible en México, ya han pasado varios años y siguen sin poder permitir usarlo

### 1/5 — ???

*2022-01-13, version 1.1.1*

when i try to download it on my applewatch, it says it requires an iphone. but when i try to download it from my iphone, it says it can only be downloaded on an applewatch. if anyone knows how to solve this please let me know!! super frustrating.

### 1/5 — Incluyan a Mexico

*2022-01-05, version 1.1.1*

Apoyo al comentario que no incluyan a su vecino que somos grandes compradores de Apple :(

### 1/5 — ECG

*2021-12-27*

It would be nice a virtual “print out” of your ECG that even though it can’t tell you about your underlying rhythm your Doc can at least look at it when you have symptoms
