Answer:
Heart rate is a measurement of how many times your heart beats in one minute.
Resting heart rate is how many heart beats you have per minute when you aren’t exercising or otherwise under stress. Resting heart rate can be an important measure of the health of your heart muscle.
It’s helpful to be able to check your own heart rate for your general health, when exercising, or if you experience symptoms such as dizziness.
You may also need to check your child’s pulse or check someone’s pulse in an emergency situation after you’ve called 911 in order to determine if CPR is needed.
Your age and fitness level have a big impact on your resting heart rate. All of the following can also affect your heart rate:
temperature
body position, such as lying, sitting, or standing
emotional state
caffeine intake
certain medications
underlying heart or thyroid conditions
There are a number of ways to check your pulse. Here are some of the most common methods:
Method 1: Radial pulse
To check your pulse using this method, you’ll be finding the radial artery.
Place your pointer and middle fingers on the inside of your opposite wrist just below the thumb.
Don’t use your thumb to check your pulse, as the artery in your thumb can make it harder to count accurately.
Once you can feel your pulse, count how many beats you feel in 15 seconds.
Multiply this number by 4 to get your heart rate. For instance, 20 beats in 15 seconds equals a heart rate of 80 beats per minute (bpm).
Method 2: Carotid pulse
To check your pulse using this method, you’ll be finding the carotid artery.
Place your pointer and middle fingers on the side of your windpipe just below the jawbone. You may need to shift your fingers until you can easily feel your heart beating.
Count the pulses you feel for 15 seconds.
Multiply this number by 4 to obtain your heart rate.
Method 3: Pedal pulse
You can also find your pulse on the top of your foot. This is called the pedal pulse.
Place your index and middle fingers above the highest point of the bone that runs along the top of your foot. You may have to move your fingers along the bone or slightly to either side to feel the pulse.
Once you have found your pulse, count the beats for 15 seconds.
Multiply by 4 to obtain your heart rate.
Method 4: Brachial pulse
Another location for checking your pulse is the brachial artery. This method is used most commonly in young children.
Turn your arm so it’s slightly bent and your inner arm is facing up toward the ceiling.
Place your index and middle fingers along the side of your arm between the crook of your elbow on the top and the pointy part of your elbow bone on the bottom. Then move your fingers an inch up your arm. You may have to press quite firmly to feel your pulse.
Once you can feel the pulse, count how many beats occur in 15 seconds.
Multiply this number by 4 to obtain your heart rate.
Method 5: Checking your heart rate with an assistive device
There are a number of devices that can tell you your heart rate, such as:
at-home blood pressure machines
digital fitness trackers
smartphone apps
exercise machines
The most accurate device for checking your heart rate is a wireless monitor that’s strapped around your chest. It reads out to a fitness tracker worn on your wrist.
Digital fitness trackers worn on the wrist, at-home blood pressure machines, and smartphone apps are less accurate than checking your heart rate manually. However, these devices are fairly accurate and very useful when exercising.
Exercise machines may have metal hand grips to read your heart rate, but these are often very inaccurate. To check your heart rate while exercising, it’s most effective to check manually or to use a digital fitness tracker.
