ECG app on Apple Watch Series 4 or later, allows users to take an electrocardiogram (ECG/EKG) which records the timing and strength of their heartbeat. In the latest watchOS 7.2 update, Apple has released ECG version 2 with improvements to the heartbeat tracking app.
watchOS 7.2 brings many new features and improvements to the Apple Watch experience by launching a new subscription-based Apple Fitness+ home workouts service, low cardio fitness notifications, and braille displays, a new accessibility feature on the smartwatch. The ability to record ECG and share data with doctors is a great health feature for anyone who is at risk or is a heart patient. Here are all the changes in ECG version 2.
All changes in ECG app version 2 on Apple Watch
As detail on the ECG app’s support page, Apple has made changes in Atrial fibrillation range, measurement due to low heart rates, a new classification, rate of inclusive tests on updated app, and more in the ECG version 2.
- The updated app now allows AFib (Atrial fibrillation) to check between 50 and 150 BPM. This means that heart rate below 50 and above 150 BPM will give inconclusive results. The previous version can check for AFib between 50 to 120 BPM.
- Poor Recording is a new classification on the app which alerts the users to check for deterents affecting a successful reading like loose Apple Watch, position of the arm, sweat, electronical interferecnes and others.
- In the updated version 2 of ECG app, the rate of successfull reading is higher than the previous version 1.
“The ECG app version 2 was also tested in a clinical trial with approximately 546 subjects, and demonstrated 99.3% specificity with respect to sinus rhythm classification, and 98.5% sensitivity for AFib classification for the classifiable results.”
