Unlocking Cardio Wellness: Harnessing the Power of Apple Watch For Heart Health ❤️


February marks Heart Month and there’s no better time to raise awareness about the importance of cardiovascular health.

For Apple Watch users, there are five key ways users can stay closer to their heart health

Apple is committed to empowering its users to be at the centre of their health.

Apple Watch is equipped with powerful features to notify users of possible underlying health conditions, giving them the agency to act on this information, and nearly every day, we hear from users on how they’ve been able to do just that. 

1. Cardio FitnessThe Cardio Fitness feature provides a scientifically validated estimate of VO2 Max (your body’s ability to intake oxygen during exercise).

The American Heart Association recognizes VO2 Max as a powerful predictor of overall health. 

Users can even opt-in to receive a notification if their classification drops to “low,” which is associated with risks of serious long-term health conditions.

Fortunately, it is something you can improve by exercising more frequently or more rigorously, and something you can easily track along the way. 

2. High and low heart rate notificationsApple Watch passively checks for unusually high or low heart rates when you are at rest, which could be signs of a serious underlying condition.

This could help users identify situations that may warrant further evaluation. If a user’s heart rate is above 120 bpm or below 40 bpm while they appear to have been inactive for 10 minutes, they will receive a notification. Users can adjust the threshold bpm or turn these notifications on or off.3. 

Irregular rhythm notificationsThe irregular rhythm notification feature on your Apple Watch will occasionally look at your heartbeat to check for an irregular rhythm that might be suggestive of AFib.

AFib is a type of irregular heart rhythm where the upper chambers of the heart beat out of sync with the lower chambers. 

Some individuals with AFib don’t experience any symptoms, and if left untreated, AFib lead to heart failure or blood clots that may lead to stroke. 

4. ECG appWith the ECG app, users who experience symptoms, such as rapid or skipped heartbeat, can capture an ECG and record their symptoms. 

The ECG app uses the electrical heart sensor built into the Digital Crown and the back crystal to record a single-lead ECG. 

The recorded waveform, results, date, time, and any symptoms are recorded and can be exported from the Health app as a PDF to share with a clinician. 

5. Afib HistoryThe first-of-its-kind AFib History gives you an estimate of the amount of time your heart shows signs of AFib, for users who have been diagnosed with the condition.

Research has shown the amount of time spent in AFib can relate to severity of symptoms, quality of life issues and risk of complications. 

AFib History also allows users to track specific life factors like sleep, exercise and weight, which may influence the amount of time spent AFib. 

Historically, there hasn’t been an easy way to track AFib over time or to compare them to important life factors. Now you can do this simply by wearing an Apple Watch.
