Set up
To set up ECG, open
Health on your iPhone, and
open the Heart option. You
should see an option to Set Up
ECG App. Follow the steps
indicated. Once you’ve set up
the app, you should see it

the latest iOS and watchOS.

Ta ke a

reading

Open the ECG app and rest

your arm on a table or your

lap. With your opposite hand,

hold your index finger on

the Digital Crown, but do not

press it. The recording takes

30 seconds, so for the best

results, don’t move during

this reading time.

View results

Once the test is

completed, you can view

results in the Health app

on your iPhone. The app

classifies results into Sinus

Rhythm, Atrial Fibrillation,

Low or High Heart Rate, or

Inconclusive. You can export

the results as a PDF to share

with your doctor if you want.

KEY FACT

While PPG requires

contact with the skin,

there’s a remote

contactless version that

uses video to analyze

subtle changes in the skin

color when blood flows.

This is not visible to the

human eye. Studies have

shown it can be achieved

with a regular camera, so

maybe one day you’ll be

able to read your heart

rate using the camera on

your iPhone!

EXPLAINED Taking an ECG reading

JARGON BUSTER

Atrial fibrillation is a heart

condition that causes the

heart to beat abnormally

fast, or irregularly. There’s

no known cause, but it’s

known to be impacted by

smoking and drinking.
