February is Heart Month in the US and the beginning of the year is a time
when many people have a fresh focus on health and fitness. With that in
mind, let's look at 7 valuable ways you can check and improve heart health
with Apple Watch.
Whether you've recently gotten an Apple Watch, or are considering one, or
have had one for years, you should be able to find some useful features to
check and improve your heart health in our round-up.
High and low heart rate notifications
. If you'd like an alert when your heart rate dips below or rises above a
certain threshold and remains there for 10 minutes while inactive, this
feature is available for those 13 years old and up.
. If you didn't turn it on the first time opening the Heart Rate app or want
to change it:
1. Open the Watch app on your iPhone
2. Swipe down and choose Heart (under the My Watch tab)
3. Tap High Heart Rate > pick a threshold
4. Tap Low Heart Rate > pick a threshold
Irregular heart rhythm notifications
Here's what this feature does:
"If you receive a notification, the irregular rhythm notification feature on
your Apple Watch identified an irregular rhythm suggestive of AFib and
confirmed it with multiple readings.
If you have not been diagnosed with AFib by a physician, you should talk to
your doctor.
To make sure this feature is set up:
1. Open the Health app on your iPhone
2. Choose Browse in the bottom right corner
3. Now tap Heart
4. Swipe down and look for Set Up under Irregular Rhythm Notifications
5. If you don't see that in the Health app, open the Watch app on iPhone
6. Swipe down and tap Heart (under the My Watch tab)
7. Tap the toggle next to Irregular Rhythm
ECG and AFib History
. The ability to take ECGs with Apple Watch arrived with Apple Watch Series
4 in 2018 starting in the US. In the years since, the valuable and
impressive feature has expanded to over 100 countries.
. ECGs are for Apple Watch users at least 22 years old. If you haven't used
it before or didn't set it up when you first got your watch:
1. Open the Health app on your iPhone
2. Choose Browse in the bottom right corner
3. Now tap Heart > ECG > Set Up
4. You can also set up the more recent AFib History feature - this
regularly checks for signs of AFib in the background
5. Head back to the Health app on your iPhone
6. Browse > Heart > look for Set Up near the bottom under AFib History
Apple highlights that after an ECG "Regardless of the result, if you aren't
feeling well or are experiencing any symptoms, you should talk to your
doctor."
Cardio Fitness
Here's how Apple describes Cardio Fitness (VO2 max):
"Cardio fitness is a measurement of your VO2 max, which is the maximum
amount of oxygen your body can consume during exercise. Your cardio fitness
level is a strong indicator of your overall physical health and a predictor
of your long-term health."
Cardio Recovery
Like HRV and VO2 max, Cardio Recovery or heart rate recovery is a
lesser-known health metric that's measured by Apple Watch every time you
track a workout. Cardio Recovery measures how much your heart rate decreases
immediately after exercise. As with heart rate variability, heart rate
recovery (HRR) offers a look at your heart health by how fast it responds to
the autonomic nervous system.
Heart rate variability (HRV)
Heart rate variability (HRV) is automatically captured by Apple Watch but
it's not viewable in the wearable's native Heart Rate app. You'll need to
head to the iPhone's Health app > Browse > Heart.
What is HRV?
It's the measurement of how the interval of time between heartbeats
changes, measured in milliseconds - notably this is a metric that changes a
lot, so looking at broad trends, not daily numbers is most helpful.
HRV is considered by many in the medical field as a powerful indicator of
not only current overall health and resilience of the heart and body but
also a strong predictor of future mortality.
HRV is also often used as a signal to understand when the body is ready for
exercise or rest. All of this is thanks to HRV showing how responsive the
heart is to our autonomic nervous system.
View your heart data history
On Apple Watch
1. Head to the Heart Rate app on your Apple Watch to see daily data (app
with heart icon)
2. You'll see your current heart rate, swipe or scroll down with the Digital
Crown
3. Now you can see your resting rate, walking average, workout heart rate,
and heart rate recovery data (if you've done a workout recently)
Heart rate history on iPhone
Checking your heart rate history captured by Apple Watch on iPhone gives you
the most data, here's where to find it:
1. Open the Health app on your iPhone
2. Tap the Browse tab in the bottom right corner, then Heart
3. On the main page, you'll see the various heart rate categories. Tap one
to see your history
4. At the top, you can change the data window between hourly, daily, weekly,
monthly, and yearly (H, D, W, M, Y)
5. Toward the bottom, you'll see heart rate highlights and more information
about each type of heart rate data
Further down in the main Heart section, you'll see more data like Cardio
Fitness, ECG results, blood pressure readings, and low/high/irregular heart
rate notifications.
Bonus features -
Vascular Age and Blood Pressure
Compatible with Apple Health, the Withings Body Cardio smart scale offers a
Vascular Age feature that measures the "speed at which the blood pressure
pulse propagates through the circulatory system."
With those measurements, the smart scale is able to determine your arterial
stiffness and health with a comparison to the average of people in your age
group.
Body Cardio
also tracks weight, BMI, body composition (water, fat, bone, and muscle),
heart rate tracking, and more.
And if you want a seamless way to measure and track your blood pressure with
Apple Health, the Withings BPM Connect is a great option.
