So, let’s get started!

What is ECG?

For people who aren’t ‘au fait’ with medical terminology: Electrocardiogram aka ECG is a medical test that records the timing & strength of electrical signals produced by the heart. With an ECG test, a doctor gets an insight about one’s heart rhythm & take actions if detects any irregularities which can lead to stroke or other heart-related issues.

Things You Should Know Before Getting Started With ECG Feature:

Apple really took a big step into health monitoring & has successfully graduated from Fitness Tracker to a Life-Saving Tech. But there are certain things which the company wants to clear to its users:

  • The new ECG feature is not meant for detecting heart attacks.
  • It cannot check signs for blood clots or stroke.
  • The ECG app is not intended to sense heart-related conditions like cholesterol, blood pressure or arrhythmia.
  • The feature can only monitor & alert irregular heart rhythms & detect Atrial Fibrillation (AFib) which can increase the risk of stroke, heart failure or other heart-related issues!

What does Apple’s ECG Feature do?

Before diving into whys & wherefores of Apple Watch’s ECG feature, let’s get to know what it’s actually doing.

To put it briefly, it’s designed to monitor the electrical patterns of heartbeat. It’s measured through the ‘Heart Rate Monitor’ present underneath the watch. You need to place your finger on the Digital Crown for at least 30 seconds. It will let the ECG app check pulses & analyses whether both upper & lower chambers of the heart are beating in rhythm or not. If not, then it could be a sign of Atrial fibrillation (AFib).

  • Tap Set Up ECG App.

Once the electrical measures are recorded, you can get any of the following results:

Sinus Rhythm – Appears when upper & lower chambers of the heart are not beating in sync.

Low or high heart rate – Heart rhythm under 50 BPM or over 120 BPM.

Atrial fibrillation – Means the heart is beating in an irregular pattern.

Inconclusive – Means the measured recordings cannot be accurately classified, because you’re not resting your arms or have worn the watch very loose.

How to view & share your Health information with the Doctor?

Once the ECG test is complete, all the measured recordings would be automatically saved in Health app. To share the details with your personal physician:

  • Launch the Health app on your iPhone.
