We often hear of how ru Apple Watch saves someone, whether it’s the ability to call for help after a car accident or where someone has fallen overboard form a boat.

On this occasion the Apple Watch has been accredited to picking up signs of AFib.

The user first had notifications on his watch that his heart beat was irregular he then went on to use the EKG feature the watch then said “You should contact your doctor, as you may be in AFib.”

The wife of the user wrote on a Facebook “In April, my husband bought an Apple Watch. Honestly, I thought it was a frivolous purchase. Who needs to get email and text notifications on their watch??”

“In June, Clark began getting notifications on his watch that his heart beat was irregular. After a few of these notifications, he used to EKG app on his watch and the results said, You should contact your doctor, as you may be in AFib.”

“As I write this, Clark is resting in the hospital after having cardiac ablation surgery today for AFib and atrial flutter. The surgeon said there was scarring to indicate this has been going on for quite some time. Clark sees his GP every other month to monitor his diabetes, and has regular bloodwork, but nothing ever indicated the need for cardiac exploration. Thank goodness for Apple Watch!!!”

Atrial fibrillation (also called AFib or AF) is a quivering or irregular heartbeat (arrhythmia) that can lead to blood clots, stroke, heart failure and other heart-related complications. At least 2.7 million Americans are living with AFib.

Apple first introduced the EKG in the series 4 Apple Watch and was initially met with some skepticism as it’s not the full 12 lead which you find in Hospitals, however, the EKG has proven on several occasions that it is capable of detecting issues and prompting users to seek medical help.
