Maximum Heart Rate: How Its Measure And What It Means
But what happens if your heart rate climbs too high during exercise and how do you know what too high is? Theres a term called maximum heart rate, referring to how fast your heart beats when maximumly stressed. There are a number of ways to measure or estimate maximum heart rate. The most reliable way is to do a maximum exercise stress test.
For a maximum stress test, a technician asks you to walk briskly on a treadmill while the incline gradually increases to make the exercise harder as they monitor your heart rate. Your heart rate will continue to rise as the challenge increases, but at some point, it reaches a plateau where it stops going up, despite the intensity increasing. This heart rate is your maximum heart rate.
Since not everyone can rush out and get maximum exercise stress test, there are formulas for estimating maximum heart rate with varying degrees of accuracy. The most common formula is to subtract your age from 220. Although studies now show this isnt the most accurate formula, its the simplest and most practical and gives a reasonable estimate of maximum heart rate.
Once you have your calculated maximum heart rate, based on your age, you can use it to monitor exercise intensity. For example, moderate intensity exercise corresponds with 50 to 70% of your maximum heart rate. If youre doing a high-intensity or HIIT workout, your heart rate should be between 70 and 90% of your maximum heart rate.
When Your Heart Rate Slows
Sometimes our hearts beat slower than 60 beats per minute. This is called bradycardia. For some people, like athletes and healthy, young adults, this heart rate could be normal. But for others, it could be caused by your brain and other organs not getting enough oxygen to function like they should.
If thatâs the case, you may feel faint, dizzy, weak, or short of breath. You might also have chest pains, memory problems, or tire easily.

Heart Rate Vs Blood Pressure: What You Need To Know
Your heart rate and blood pressure measure two different things, but doctors can use both of them to evaluate certain aspects of your health. The heart rate records the number of times that your heart beats per minute, while your blood pressure quantifies how strong your blood moves through the blood vessels.
Does Your Heart Rate Affect Your Blood Pressure?
Your heart rate and your blood pressure do not automatically increase at the same rate. Its possible for your heart rate to safely increase twice as much as the normal heart rate while your blood pressure only increases a minimal amount. In fact, even when your heart beats above the normal number of times per minute, healthy blood vessels can become larger for easier blood flow. For instance, your heart rate increases when you exercise which helps more blood to reach your muscles.
Aside from physical activities, your heart rate may also be affected by air temperature, your emotions, your body position, your body size and use of medications.
How Can You Measure Your Heart Rate?
You can easily check your heart rate, whether youre exercising or doing your normal chores, by wearing an activity tracker. But if you dont use one, you can also measure it manually by doing the following:
You may also find a pulse and measure your heart ra
te on the side of your neck, the inside of your elbow or the top of your foot.

If youre an athlete or serious fitness fanatic, you might like to take your body to the brink to see how it performs. If thats the case, your heart and lungs are likely conditioned to handle this extreme level, even if its just for a brief period of time. But if youre an average gym-goer, runner or cyclist, you might be wondering how high is too high for you.
According to Dr. Doshi, there is no single danger zone. How high you take your heart rate during exercise, he says, depends on several variables, including your fitness level and underlying medical problems. You need to listen to and understand your body when pushing the limits, Dr. Doshi says. And be aware of symptoms such as severe shortness of breath, chest pain, dizziness or severe heart palpitations, which are all signs that you need to slow down, he adds.
Although you can go over the theoretical calculated maximal heart rate, Dr. Doshi says its important to note that this formula generalizes people and doesnt correct if youre an older athlete or an extremely fit person. Thus, Dr. Doshi recommends discussing your needs with your doctor or health care provider. If youre new to exercise or have a medical condition, they can help you determine a safe zone for getting started.
If you want to train at your maximal heart rate, consider consulting an exercise physiologist who can help you find your baseline max heart rate and monitor you while you exercise.
How To Manage Your Zone
Tachycardia is the medical term for an excessively fast heart rate. While a fast heart rate during rest may have a variety of causes, a fast heart rate during a workout may simply be the result of exercising at too difficult a level of intensity. Decreasing the intensity of your workout may help bring your heart rate back into the target zone. If youve found working out frustrating and defeating, it may be because youve been working to the wrong numbers.

A racing heart can be scary.
Heart attack? Panic attack? The symptoms can be similar.
A fast-beating heart may be concerning or it could just be anxiety, which can come and go. A normal pulse or heart rate is between 60 and 100 beats per minute taken when youre not exercising, known as your resting heart rate.
Anything that causes increased stimulation, whether physical or emotional, could increase your heart rate. That includes caffeine and other herbal and medicinal stimulants.
How To Measure Heart Rate
Measuring your heart rate is as simple as checking your pulse. You can find your pulse over your wrist or neck. Try measuring your radial artery pulse, which is felt over the lateral part your wrist, just below the thumb side of your hand.
To measure your heart rate, gently press the tips of your index and middle fingers over this blood vessel in your wrist. Make sure not to use your thumb, because it has its own pulse and may cause you to miscount. Count the beats you feel for a full minute.
You can also count for 30 seconds and multiply the count by two, or count for 10 seconds and multiply by six.
Alternatively, you can use a heart rate monitor, which determines your heart rate automatically. You can program it to tell you when youre above or below your target range.

IST is often hard to treat. If you have severe symptoms that dont respond to these treatments, you may need catheter ablation. This procedure uses energy to destroy a very small part of the heart that is triggering the tachycardia. But it doesnt always work because the whole heart can be abnormal. There is also a small risk that destroying too much heart tissue might make a permanent pacemaker necessary.

Heart Rate by Age
The traditional method, also known as HRmax, is a simple way of gauging your maximum heart rate. Start by subtracting your age from 220. Then, use the result to calculate your range.
For example, if youre 50 years old, the calculation would be: 220 50 = 170 . To calculate your heart rate on the high end of the suitable range , multiply 170 by 0.75 to get about 128 beats per minute .
Heart Rate by Age and Gender
Heart Rate by Age and Resting Heart Rate
For example, a 50-year-old with a resting heart rate of 65 would calculate as follows:
- 220 50 = 170 for HRmax
- 170 65 = 105 for RHR
- + 65 = about 144 bpm

Factors That Can Affect Resting Heart Rate
In addition to age, a few other factors can affect your resting heart rate.
- Temperature. Your heart rate may increase slightly when youre exposed to hot temperatures.
- Medication side effects. Medications, like beta-blockers, can lower your resting heart rate.
- Emotions. If youre anxious or excited, your heart rate may increase.
- Weight. People with obesity may have a higher resting heart rate. This is because the heart has to work harder to supply the body with blood.
- Anemia. In anemia, low levels of red blood cells can cause the heart to beat faster in order to supply your body with oxygen-rich blood.
- Endocrine or hormonal abnormalities. Abnormal levels of some hormones can influence heart rate. For example, too much thyroid hormone can increase heart rate while too little thyroid hormone can decrease heart rate.
- Postural tachycardia syndrome . This syndrome produces an abnormal increase in heart rate after sitting up or standing. In addition to heart palpitations, some typical symptoms of PoTS include dizziness and fainting.
- Body positioning. Heart rate can increase temporarily when you move from a sitting to a standing position.
- Smoking. Smokers tend to have a higher resting heart rate. Quitting smoking can help bring it back down. This is often difficult, but a doctor can help build a cessation plan that works for you.
Your maximum heart rate is a calculation that helps you figure out what your ideal target heart rate is during exercise.
What Are The Types Of Tachycardia
There are 3 types of tachycardia.
- Supraventricular where problems with the electrical signals in the upper chambers of the heart cause the heart to beat faster. This reduces blood flow to the rest of your body because your heart can’t pump blood as effectively. Two common types of supraventricular tachycardia are atrial flutter and atrial fibrillation.
- Ventricular where problems with the electrical signals in the lower chambers of the heart cause the heart to beat faster. This affects its ability to pump blood to the rest of your body.
- Sinus tachycardia where the natural pacemaker in your heart sends electrical signals faster than normal. This can be in response to a stressor described below, or it can be a sign of anaemia, problems with the thyroid gland or general ill health.
