Does Heart Rate Increase Or Decrease With Age
As you grow older, your resting heart rate does not change very much, though your heart cant beat as fast during physical activity or stress as it did when you were younger, according to the National Institute on Aging.
- Body size
- Body position
If your resting heart rate changes drastically, talk to your doctor. A higher resting heart rate can be a sign of a heart problem, so if you are an adult with a resting heart rate of 80 to 100 BPM, you might be at risk.
Keeping track of your heart rate can help you improve your overall health and adjust your exercise routine to stay healthy. Want to learn more about your heart? Visit the UPMC Heart and Vascular Institute online.
How Is An Arrhythmia Diagnosed
Doctors use several tools to diagnose arrhythmias. Its very important to know a childs medical history and give this information to the doctor. The doctor will use the medical history, along with a physical exam, to begin the evaluation.
If an arrhythmia is suspected, the doctor will order an electrocardiogram to measure the hearts electrical activity. For this painless test, the child will lie down and have small metal tabs fixed to the skin with sticky papers. The electrodes have wires attached to them, which connect to the EKG machine. The electrical signals from the heart are then briefly recorded, usually for just 10 seconds. This information is sent to a computer, where its interpreted and drawn as a graph.
These types of EKG tests might be recommended:
Influences From The Central Nervous System
The heart rate is rhythmically generated by the sinoatrial node. It is also influenced by central factors through sympathetic and parasympathetic nerves. Nervous influence over the heart rate is centralized within the two paired cardiovascular centres of the medulla oblongata. The cardioaccelerator regions stimulate activity via sympathetic stimulation of the cardioaccelerator nerves, and the cardioinhibitory centers decrease heart activity via parasympathetic stimulation as one component of the vagus nerve. During rest, both centers provide slight stimulation to the heart, contributing to autonomic tone. This is a similar concept to tone in skeletal muscles. Normally, vagal stimulation predominates as, left unregulated, the SA node would initiate a sinus rhythm of approximately 100 bpm.
Norepinephrine binds to the beta1 receptor. High blood pressure medications are used to block these receptors and so reduce the heart rate.
Input to the cardiovascular centres
Increased metabolic byproducts associated with increased activity, such as carbon dioxide, hydrogen ions, and lactic acid, plus falling oxygen levels, are detected by a suite of chemoreceptors innervated by the glossopharyngeal and vagus nerves. These chemoreceptors provide feedback to the cardiovascular centers about the need for increased or decreased blood flow, based on the relative levels of these substances.

What Is A Resting Heart Rate
Before we explain the resting part, lets quickly cover heart rate.
Put simply, your heart rate is the number of times your heart beats every sixty seconds. Along with body temperature, blood pressure, and breathing rate, its one of the vital signs when it comes to monitoring body health and knowing how to measure it can help you keep a close eye on your own physical fitness.
Your resting heart rate, therefore, is the number of times your heart beats when youre at rest.
In this article, we explore what a good resting heart rate looks like at different ages, why measuring your heart rate matters, and talk you through how to do it yourself. But first

What Your Heart Rate Says About Your Cardiovascular Health
Your heart is responsible for pumping blood and oxygen throughout your body and if youre having heart troubles, the rest of your body will be impacted too.
A higher resting heart rate can be dangerous because it taxes the heart, making it work harder. This is linked to a higher risk of heart disease and death, just like high blood pressure or high cholesterol. Resting heart rates that near or exceed 100 should be brought to the attention of your doctor.

When Should I Worry About My Heart Rate
Before you become worried over your heart rate, it is important to know the things that can increase or decrease your heart rate.
Your heart rate might be increased
- Soon after you consume coffee or smoke
- Whenever you feel scared, anxious, or stressed out
- If the climate is hot and humid
- If you are obese
- If you are on certain medicines like decongestants
- If you indulge in binge drinking frequently
Health conditions that may increase your heart rate and could be improved upon by treatment
Some conditions like supraventricular tachycardia may cause a sudden increase in your heart rate at rest. This is a medical emergency and needs immediate medical attention. This condition may lead to sudden death.
Consuming heavy amounts of alcohol frequently can lead to a fast and irregular heart rate . This again is a medical emergency.
A persistent high heart rate can also mean that the heart muscle is weakened, which forces it to pump harder to deliver the same amount of blood.
You may have a lower resting heart rate due to
- Exercising regularly
- Low levels of thyroid hormones in the body
You should also be concerned about your heart rate if you notice your heart beating on an irregular rhythm frequently. This can be a serious condition known as arrhythmia for which you should see your doctor right away.
How To Lower Your Resting Heart Rate
In general, people who are more fit and less stressed are more likely to have a lower resting heart rate. A few lifestyle changes can help you slow it down:
- Exercise regularly. It raises your pulse for a while, but over time, exercise makes your heart stronger so it works better.
- Eat right. Losing weight may slow your resting heart rate. And studies have found lower heart rates in men who eat more fish.
- Tackle stress. Set aside time to disconnect from electronic devices and relax each day. Meditation, tai chi, and breathing exercises can also help.
- Stop smoking. Itâs one of the best things you can do for your overall health.

How Do I Take My Heart Rate
There are a few places on your body where itâs easier to take your pulse:
- The insides of your wrists
- The insides of your elbows
- The sides of your neck
- The tops of your feet
Put the tips of your index and middle fingers on your skin. Press lightly until you feel the blood pulsing beneath your fingers. You may need to move your fingers around until you feel it.
Count the beats you feel for 10 seconds. Multiply this number by six to get your heart rate per minute
When To Call Your Healthcare Provider
Certainly, an abnormal respiratory rate is a reason to contact your healthcare provider, especially if you have a condition such as asthma or heart disease, as an increased respiratory rate alone can be a warning sign that should be heeded.
At the same time, healthcare professionals should be cognizant of this often ignored vital sign. One study found that measuring respiratory rate around the time of discharge from the emergency room was a very important predictor of deterioration after discharge.

What Abnormal Results Mean
Resting heart rates that are continually high may mean a problem. Talk to your health care provider about this. Also discuss resting heart rates that are below the normal values .
A pulse that is very firm and that lasts for more than a few minutes should be checked by your provider as well. An irregular pulse can also indicate a problem.
A pulse that is hard to locate may mean blockages in the artery. These blockages are common in people with diabetes or hardening of the artery from high cholesterol. Your provider may order a test known as a Doppler study to check the blockages.
Arrhythmia Tachycardia And Other Conditions
A number of conditions can affect your heart rate. An arrhythmia causes the heart to beat too fast, too slow or with an irregular rhythm.
Tachycardia is generally considered to be a resting heart rate of over 100 bpm, according to the National Institutes of Health, and generally caused when electrical signals in the heart’s upper chambers fire abnormally. If the heart rate is closer to 150 bpm or higher, it is a condition known as supraventricular tachycardia . In SVT, your hearts electrical system, which controls the heart rate, is out of whack. This generally requires medical attention.
Bradycardia, on the other hand, is a condition where the heart rate is too low, typically less than 60 bpm. This can be the result of problems with the sinoatrial node, which acts as the pacemaker, or damage to the heart as a result of a heart attack or cardiovascular disease.

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 , which can put you at greater risk of having a stroke. Fortunately, if you have AF, there’s medication you can take to help reduce this stroke risk.
Your doctor can do a simple test called an ECG to further check your irregular pulse.
How Do You Know Your Heart Rate
Your heart rate is a measure of how fast your heart beats and is also an important indicator of good health. Your doctor will always make it a point to measure your heart rate whenever you visit him for your routine health checkup or any health-related problem.
While the heart rate is routinely examined by your doctor, you can also measure your heart rate. With the help of your middle finger and index finger, you have to first try to feel and locate your pulse at any of the following places
- The inner side of your elbow
- The base of the toe
- The side of your neck
The wrist is the most commonly used and convenient place to check your heart rate. Once you locate the pulse on your wrist, you have to gently press on it for 60 seconds and count the beats. This is how you will know your heart rate, which will be in beats per minute.

How Is An Arrhythmia Treated
Many arrhythmias dont need treatment. For those that do, these options might be used:
- Medicine. Doctors may prescribe anti-arrhythmic medicines depending on the type of arrhythmia and other considerations. Sometimes, these can increase symptoms and cause side effects, so the patient will be closely watched by the doctor.
- Pacemakers. A pacemaker is a small battery-operated device implanted into the body through a surgical procedure. Connected to the heart by a wire, a pacemaker can detect if the heart rate is too slow and send electrical signals to speed up the heartbeat.
- Defibrillators. A small battery-operated implantable cardioverter defibrillator is surgically placed near the left collarbone. Wires run from the defibrillator to the heart. The ICD senses if the heart has a dangerously fast or irregular rhythm and sends an electrical signal to restore a normal heartbeat.
- Catheter ablation. A catheter is guided through a vein in the leg to the heart. Arrhythmias often are caused by microscopic defects in the heart muscle. Once the problem area of the heart is pinpointed, the catheter heats or freezes the defective muscle cells and destroys them.
- Surgery. Surgery is usually recommended only if all other options have failed. The child will be put under anesthesia, and a surgeon will remove the tissue causing the arrhythmia.
When Heart Rate Or Rhythm Changes Are More Serious
Irregular heartbeats change the amount of blood that flows to the lungs and other parts of the body. The amount of blood that the heart pumps may be decreased when the heart pumps too slow or too fast.
Changes such as atrial fibrillation that start in the upper chambers of the heart can be serious, because they increase your risk of forming blood clots in your heart. This in turn can increase your risk for having a stroke or a blood clot in your lungs . People who have heart disease, heart failure, or a history of heart attack should be more concerned with any changes in their usual heart rhythm or rate.
Fast heart rhythms that begin in the lower chambers of the heart are called ventricular arrhythmias. They include ventricular tachycardia and ventricular fibrillation. These types of heart rhythms make it hard for the heart to pump enough blood to the brain or the rest of the body and can be life-threatening. Ventricular arrhythmias may be caused by heart disease such as heart valve problems, impaired blood flow to the heart muscle , a weakened heart muscle , or heart failure.
Symptoms of ventricular tachycardia include palpitations, feeling dizzy or light-headed, shortness of breath, chest pain or pressure, and fainting or near-fainting. Ventricular fibrillation may cause fainting within seconds and causes death if not treated. Emergency medical treatment may include medicines and electrical shock .
Check your symptoms to decide if and when you should see a doctor.

When Heart Rate Or Rhythm Changes Are Minor
Many changes in heart rate or rhythm are minor and do not require medical treatment if you do not have other symptoms or a history of heart disease. Smoking, drinking alcohol or caffeine, or taking other stimulants such as diet pills or cough and cold medicines may cause your heart to beat faster or skip a beat. Your heart rate or rhythm can change when you are under stress or having pain. Your heart may beat faster when you have an illness or a fever. Hard physical exercise usually increases your heart rate, which can sometimes cause changes in your heart rhythm.
Natural health products, such as goldenseal, oleander, motherwort, or ephedra , may cause irregular heartbeats.
It is not uncommon for pregnant women to have minor heart rate or rhythm changes. These changes usually are not a cause for concern for women who do not have a history of heart disease.
Well-trained athletes usually have slow heart rates with occasional pauses in the normal rhythm. Evaluation is usually not needed unless other symptoms are present, such as light-headedness or fainting , or there is a family history of heart problems.
Try These Balance Exercises:
- See how long you can stand on one foot, or try holding for 10 seconds on each side.
- Walk heel to toe for 20 steps. Steady yourself with a wall if you need a little extra support.
- Walk normally in as straight a line as you can.
- If you find standing on one foot very challenging at first, try this progression to improve your balance:
- Hold on to a wall or sturdy chair with both hands to support yourself.
- Next, hold on with only one hand.
- Then support yourself with only one finger.
- When you are steady on your feet, try balancing with no support at all.

Charts Of Normal Resting And Exercising Heart Rate
The heart is an organ located just behind and slightly to the left of the breastbone, and pumps blood through a network of veins and arteries known as the circulatory system. The right atrium is sent blood from the veins, and delivers it to the right ventricle. It’s then pumped into the lungs where it is oxygenated. The left atrium is sent oxygen enriched blood from the lungs and delivers it to the left ventricle, where it’s then pumped throughout the body, and the ventricular contractions create blood pressure.
A pulse is the beating of the heart as it’s felt through the walls of an artery, such as the radial artery at the wrist. Pulse rates can also be felt and measured at the carotid artery located on the side of the neck, the temporal artery at the temple, or the femoral artery on the anterior side of the hip, and a chart showing normal heart rate can be used to check on your heart rate.
Taking Your Heart Rate
There are several places on your body where you can measure your heart rate, such as your:
- Wrist: Between the bone and the tendon over your radial artery
- Neck: Slightly to the side of the mid-line of your neck, about halfway down you can feel your carotid artery
- Elbow: Approximately an inch up the inside arm from the crook of the elbow
- Foot: On the top of the foot, halfway up and towards the middle, just past the bones and tendons that lead to the big toe.
Once you have located these pulse points, use a timer or a watch to count the number of pulses you can feel in 15 seconds. Then multiply this number by four to calculate your beats per minute.
See your doctor if your resting heart rate is regularly more than 100 beats per minute, or less than 40 beats per minute, for no obvious reason.
