What Factors Can Affect Resting Heart Rate
Several factors can affect resting heart rate: stress, alcohol or caffeine intake, or fever usually raise resting heart rate, while regular exercise or meditation can lower it. Air temperature and certain medications can also affect resting heart rate.
Heart-rate zones, which are percentages of your maximum heart rate, can help you determine the intensity of your workout or activity.
Why Should I Measure My Heart Rate Continuously
Different things can cause your heart rate to change. Mainly, your heart rate changes in response to the demands of your muscles during daily activities. For example, your heart has to pump harder when youre cycling than when youre sitting down because your heart delivers the oxygen and energy nutrients that your muscles need in order to provide more energy for your activities through your bloodstream.
Because the Continuous Heart Rate feature tracks all your daily activities, you can see what kind of health benefits your activity has, and youll get an accurate calculation of how many calories youve burned during the day. Heart rate measurements combined with activity information can help you learn what the most meaningful physical activity moments are during your day.
If your choice of physical activity includes minimal wrist movements, like when youre pushing a baby stroller, carrying groceries or cycling, your overall activity will now be tracked better with the Continuous Heart Rate feature, and also this kind of activity will now add to your progress towards reaching your Activity Goal. The higher your measured heart rate, the higher the recorded activity level will be, therefore also physical effort can be taken into account, e.g. when walking uphill or carrying a heavy backpack.

Best Devices For Measuring Heart Rate
So now you know all the different kinds of heart rate and how to measure them using clocks and math. Even though the traditional methods aren’t all that hard, there are easier — and potentially more accurate — ways to measure and track your heart rate.
Of course, the most accurate readings will come from a lab test or other clinical method. But since most people don’t have access to and don’t need those methods, these devices will work just fine.
What Is A Good Hrv Number
Unlike heart rate, HRV varies greatly from individual to individual due to genetics . A good HRV number is relative to where an athletes rolling baseline is. This makes it incredibly tough to pinpoint a good HRV that will fit everyone. Many things can influence ones HRV, including:
While there is no ideal HRV number that will fit everyone, a higher HRV is generally considered to be a more positive indicator of overall wellness and suggests that the bodys sympathetic and parasympathetic nervous systems are highly responsive.
To help provide context, Mike Lombardi, Elite Performance Manager at WHOOP, shared examples of two WHOOP athletes who are equally fit, but with different HRVs:
Lets look at a couple anecdotal examples. My wife was a 2012 Olympian and she has an average HRV of about 60. Then on the other end of the spectrum, we have someone in the office who does triathlons and half Ironman races, and her average HRV sits around 220. In reality, theyre probably equivalently fit in terms of capacity.
What Lombardi is saying is that both of these athletes are incredibly fit, but their rolling baselines are very different. If athletes can understand where they normally sit on a day-to-day optimal training basis, then they can augment variables in their personal lives to facilitate the HRV responses they want.
If HRV varies so greatly, is there such a thing as a poor HRV?

How do we calculate HR is the rhythm is not regular, such as in atrial fibrillation? It may be even easier, like finger counting
Heart rate: 20 QRS complexes x 6 = 120 bpm
Usually electrocardiograms record 10 seconds, so all you have to do is count all QRS and multiply by 6.
If the EKG is not a 10 seconds one, or you are not aware of its duration, count 30 large squares , and multiply the number of QRS complexes on them by 10. The result is an approximate heart rate.
For example: Count the number of QRS complexes in 30 large squares and multiply by 10. If there are 11 QRS complexes, the heart rate is 110 bpm .

Measuring your heart rate is any easy way to gauge your health, as it provides a real-time snapshot of your heart muscle function. For most adults, a normal resting heart ratethe number of heartbeats per minute while at restranges from 60 to 100 beats per minute. A normal heart rate can vary from person to person. However, an unusually high or low resting heart rate can be a sign of trouble.

Heart Rate Variability Origins
In 1733, Rev. Stephen Hales became the first person to formally document that heart beats and arterial pressure levels vary during the respiratory cycle . Following Hales in 1847, Carl Ludwig became the first to record the variations and oscillations that occurred during the respiratory cycle, which eventually became known as respiratory sinus arrhythmia .
In the late 1800s and early 1900s, Dutch physician Willem Einthoven became the first to document the electrical current of the heart, which is known as electrocardiogram . After Einthovens discovery, ECG became standardized and developed over the following years, and in 1960 the ambulatory ECG was used in wide practice .

In the 1970s, power spectral analysis was used to study the physiological differences in beat-to-beat variability, thus creating the birth of HRV. Multiple studies since have investigated the physiological components that could be at play and responsible for each individuals HRV .
In the early days of HRV research, many scientists speculated that there was some form of neural activity at play, but it was still too new to draw strong suggestions .
How To Measure Resting Heart Rate
To determine your resting heart rate the old-school way, simply count how many times your heart beats in a minute. Your reading will be more accurate if you measure it in the morning before you get out of bed. To measure your resting heart rate, follow these steps:
- Choose a location at which you can feel your pulse. The best places to find your pulse are on your wrists, the insides of your elbows, the tops of your feet and the side of your neck, just under your jaw.
- Place two fingers on the pulse location, and count the number of beats you feel in 60 seconds.
Use a stopwatch during this process because it’s unlikely that you’ll be able to count both the pulse and the seconds in your head. Counting for a full 60 seconds will provide the most accurate result, but you can also count for 30 seconds and then multiply that number by two.
For example, if I count 30 pulses in 30 seconds, I’d multiply that by two to get 60 for my resting heart rate.

How Do I Track Heart Rate With My Fitbit Device
Learn how Fitbit tracks your heart rate day and night, and see tips to get a more accurate reading.
When your heart beats, your capillaries expand and contract based on blood volume changes. To determine your heart rate, the optical heart-rate sensor in your Fitbit device flashes its green LEDs many times per second and uses light-sensitive photodiodes to detect these volume changes in the capillaries above your wrist. Then your device calculates how many times your heart beats per minute . The optical heart-rate sensor detects a range of 30-220 bpm.*
We use green LEDS because they maximize the signal detected from the capillaries near the surface of the skin. The optical heart-rate sensor also uses infrared light to determine when the device is on your wrist to improve the accuracy of your heart-rate data.
*This range applies during sleep while youre awake, the range is 40-220 bpm. On Fitbit Versa 2, the range is 30-250 bpm.
Swipe up on your clock face to see your current heart rate and either your heart-rate zone or resting heart rate . To see heart rate details, tap or swipe .
If your device has an Exercise app, you can check your real-time heart rate and heart-rate zone during a workout. Note that your device doesn’t track your heart rate during swims.
What Happens When I Receive A Heart
When your Fitbit device detects your heart rate goes above or below your personal heart rate threshold while youre inactive, you receive a notification on your Fitbit device. Tap Open, and then tap the notification in the Fitbit app to learn more about your data and complete a survey where you log any potential factors, medications, and symptoms.

The Heart Rate Magic Number
On a normal electrocardiogram, there are five large squares per second and 300 per minute. Knowing this, we can calculate the heart rate measuring the R-R interval, providing the rhythm is regular.
Heart rate: 4 large square = 75 bpm
On the EKG, locate a R wave that matches a thick line, count the number of large squares to the next R wave. Heart rate is 300 divided by the number of large squares, and thatâs it!
For example: if there is 1 large square between R waves, the heart rate is 300 bpm two large squares, 150 bpm, three large squares, 100 bpm, fourâ¦ 75 bpm.

Measuring Heart Rate With Your Wearable:
When measuring your heart rate, ensure the device fits snugly on your arm above your wrist as shown in the following figure. Do not fasten the Gear too tightly.
Caution! If you feel discomfort while using the device, stop using it and remove it from your wrist. If your device becomes hot to the touch, remove it until it cools.
How These Apps Can Track Your Heart Rate
Similarly to the heart rate trackers built into most fitness wearables, apps on your phone can measure your heart rate by detecting changes in blood volume below the skin’s surface — a practice called .
Here’s how it works: Every time your heart beats, the amount of blood that reaches the capillaries in your fingers and face swells and then recedes. Because blood absorbs light, apps are able to capture this ebb and flow by using the flash of your phone’s camera to illuminate the skin and create a reflection.
How To Measure Your Resting Heart Rate
Originally published August 4, 2016 1:39 pm, updated April 16, 2020
The general rule for resting heart rate is: the lower the better. But, how to know how low or high your resting heart rate is? Heres how you can prepare for measuring your resting heart rate and how to do it in five steps.
When To See A Doctor
A consistently low heart rate is called bradycardia. In healthy young adults or trained athletes, a low heart rate with no other symptoms is usually the sign of a very healthy heart muscle.
However, a low heart rate can be a sign of a serious underlying problem. If your heart rate is lower than 60 bpm and youre experiencing chest pain, call 911. If youre experiencing dizziness, weakness, fainting, or other concerning symptoms, call a doctor.
A consistently high heart rate is known as tachycardia. Its normal to have an elevated heart rate when youre exercising, stressed, anxious, sick, or have consumed caffeine.
Its not normal to have a heart rate over 100 bpm when youre resting, especially if youre also experiencing:

How Does My Fitbit Device Calculate My Heart
The formula Fitbit uses to calculate your heart-rate zones is based on your device.
Fitbit personalizes your heart-rate zones using your heart rate reserve, which is the difference between your maximum heart rate* and your resting heart rate .
Heart rate reserve is an indication of your overall cardiovascular fitness. While your maximum heart rate is generally determined by age, your resting heart rate can be lowered by increasing your fitness level. By lowering your resting heart rate, you can increase your heart rate reserve.
For example, if you are 45 years old and your resting heart rate is 74 bpm, heres the math:
First, calculate your maximum heart rate and heart rate reserve.
|Common formula of 220 – age|
|Heart Rate Reserve||
Maximum heart rate – resting heart rate
|Target Heart Rate Per Zone||+ resting heart rate|
Next, use your heart rate reserve to calculate your personalized heart-rate zones.
|Bottom of zone: + 74 = 114 bpmTop of zone: + 74 = 134 bpm|
Bottom of zone: + 74 = 135 bpmTop of zone: + 74 = 159 bpm
|Peak Zone||Bottom of zone: + 74 = 160 bpmTop of zone: maximum heart rate|
Note that you can see your personalized heart-rate zones on the Active Zone Minutes screen in the Fitbit app.
*Occasionally during intense exercise, you might notice your heart rate go above your Fitbit-calculated maximum heart rate.

When Apple Watch Measures Your Heart Rate
When you use the Workout app, Apple Watch measures your heart rate continuously during the workout and for 3 minutes after the workout ends to determine a workout recovery rate. If you don’t see your heart rate, check your settings.
This information, as well as other data it collects, helps Apple Watch estimate how many calories youve burned. In addition, Apple Watch measures your heart rate throughout the day when youre still, and periodically when youre walking . Since Apple Watch takes these background readings based on your activity, the time between these measurements will vary. Apple Watch also calculates a daily resting rate and walking average by correlating background heart rate readings with accelerometer data when sufficient background readings are available. You can control which third-party apps have access to your health data from the Health app in Sources.
Some anomalies may appear in the displayed data, resulting in occasional heart rate measurements that are abnormally high or low.
