The average heart beats approximately blank times per minute
|
The normal heart is a strong, muscular pump a little larger than a fist. It pumps blood continuously through the circulatory system. Each day the average heart “beats” (expands and contracts) 100,000 times and pumps about 2,000 gallons of blood. In a 70-year lifetime, an average human heart beats more than 2.5 billion times. Show
The circulatory system is the network of elastic tubes that carries blood throughout the body. It includes the heart, lungs, arteries, arterioles (ar-TE’re-olz) (small arteries), and capillaries (KAP’ih-lair”eez) (very tiny blood vessels). These blood vessels carry oxygen- and nutrient-rich blood to all parts of the body. The circulatory system also includes venules (VEN’ yoolz) (small veins) and veins. These are the blood vessels that carry oxygen- and nutrient-depleted blood back to the heart and lungs. If all these vessels were laid end-to-end, they’d extend about 60,000 miles. That’s enough to encircle the earth more than twice. The circulating blood brings oxygen and nutrients to all the body’s organs and tissues, including the heart itself. It also picks up waste products from the body’s cells. These waste products are removed as they’re filtered through the kidneys, liver and lungs. What is the heart’s structure?The heart has four chambers through which blood is pumped. The upper two are the right and left atria. The lower two are the right and left ventricles. Four valves open and close to let blood flow in only one direction when the heart beats:
Each valve has a set of flaps (also called leaflets or cusps). The mitral valve has two flaps. The others have three. Under normal conditions, the valves let blood flow in just one direction. Blood flow occurs only when there’s a difference in pressure across the valves that causes them to open. How does the heart pump blood?A heart’s four chambers must beat in an organized manner. This is governed by an electrical impulse. A chamber of the heart contracts when an electrical impulse moves across it. Such a signal starts in a small bundle of highly specialized cells in the right atrium — the sinoatrial (SI’no-A’tre-al) node (SA node), also called the sinus node. A discharge from this natural “pacemaker” causes the heart to beat. This pacemaker generates electrical impulses at a given rate, but emotional reactions and hormonal factors can affect its rate of discharge. This lets the heart rate respond to varying demands. Your pulse, or heart rate, can tell you a lot about your heart. Learn about normal and abnormal heart rates and find out how to check your own pulse. Learn how to check your pulse What is your pulse?When your heart beats it pushes blood around your body. This heartbeat can be felt as your 'pulse' on your wrist or neck Your pulse is measured by counting the number of times your heart beats in one minute. For example, if your heart contracts 72 times in one minute, your pulse would be 72 beats per minute (BPM). This is also called your heart rate. A normal pulse beats in a steady, regular rhythm. However, in some people this rhythm is uneven, or 'jumps about'. This is known as an irregular pulse. How do you find your pulse? The easiest place to find your pulse is in your wrist.
How do you check your pulse (heart rate)?You can measure your heart rate manually by checking your pulse. Follow these three steps.
Also make a note of whether your heart beats at an even or uneven rhythm. A normal heart beats in a steady rhythm like a clock, tick tock tick tock. Some people like to use a heart rate monitor to measure their heart rate. These monitors are often included in fitness trackers, which are now widely available in sports stores and other retail outlets. However, their accuracy depends on the quality of the device. If you've been active, or recently had a stimulant like nicotine or caffeine, you'll need to wait at least five minutes before taking your pulse. What is a normal heart rate?A normal heart rate, when you're not being active, is generally between 60 – 100 beats per minute. This is called your resting heart rate. Athletes or people who are very fit may have resting heart beats of less than 60 bpm. When you're active, your heart beats faster to get more oxygen to your working muscles. The harder your body is working, the faster your heart will beat. For example, your heart rate when you're sprinting will be much faster than your heart rate when you're walking. If you're exercising hard, it's normal for your heart rate to get up to 160 beats per minute or more. There are other things that can make your heart beat faster, like caffeine, nicotine, recreational drugs and some kinds of medications. Your heart will also beat faster when you feel strong emotions, like anxiety, fear or excitement. What is an irregular pulse?An irregular pulse is when the heart doesn't beat in a regular, steady rhythm. This is also called an irregular heart rate or an arrhythmia. If your heart rate is irregular, you may notice that your pulse:
Why is it important to get it checked?Often an irregular pulse is harmless. However, it's important to get it checked by a health professional, because sometimes it's a sign of a heart condition. The most common kind of heart rhythm condition is atrial fibrillation (AF), which can put you at greater risk of having a stroke. Fortunately, if you have AF, there's medication you can take to help significantly reduce this stroke risk. Your doctor can do a simple test called an ECG (electrocardiogram) to further check your irregular pulse. What are heart palpitations?A heart palpitation is when you suddenly become aware of your heart beating, usually in an irregular way. Sometimes you can feel it in your ears, neck or chest when you’re lying down. Your heart beat may feel:
It is not unusual to feel heart palpitations occasionally and mostly they are harmless. However if you’re experiencing them on a regular basis, see your doctor. Exercise and heart rateLike any other muscle, your heart needs exercise to keep it fit and healthy. Regular exercise can help reduce your risk of heart disease and other health conditions, such as diabetes. To keep your heart healthy, you should aim to do 150 minutes of low to moderate intensity exercise a week. If you have a heart condition, talk to your doctor about what exercise and target heart rates are safe for you. One way to measure the intensity of your exercise is by using your heart rate. To exercise at a low to moderate intensity your heart rate should be at 50 to 70% of your approximate maximum heart rate. The easiest way to get an approximate maximum heart rate (MHR) is to calculate 220 – your age. You then need to calculate 50 to 70% of your MHR. For example, if you're 40-years-old:
Alternatively, you can use our heart rate chart below to get a rough idea. Remember if you're on medications to slow your heart rate down, you may not be able to meet these upper heart rates and the aim should be to exercise at a rate that makes you lightly puff. How many times does a heart beat per minute?A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.
Is heart rate 70 beats per minute?Pulse & Heart Rate. Your heart rate is the number of times each minute that your heart beats, which is normally between 60 and 100 times per minute for adults.
Why is heart beat 72 per minute?A normal heart rate, when you're not being active, is generally between 60 – 100 beats per minute. This is called your resting heart rate. Athletes or people who are very fit may have resting heart beats of less than 60 bpm. When you're active, your heart beats faster to get more oxygen to your working muscles.
What is the normal average heart beat rate?What's a normal heart rate? Most adults have a resting heart rate between 60 and 100bpm. The fitter you are, the lower your resting heart rate is likely to be. For example, athletes may have a resting heart rate of 40 to 60bpm, or lower.
