What Is Considered Severe Bradycardia
When a Slowed Heart Rate Means Serious Trouble In medical textbooks, bradycardia is usually defined as a resting heart rate that is below 60 beats per minute. However, many healthy people have a resting heart rate between 50-60 beats per minute, particularly athletes or sleeping people.
Can You Die From Bradycardia
When bradycardia is more severe, you may experience shortness of breath, chest pain, and fainting. If severe bradycardia goes untreated, it could lead to cardiac arrest, meaning the heart stops beating, and that can lead to death.
When To Worry About Low Heart Rate
Our heartbeat is one of our most essential biomarkers. One of the most significant statements to the significance of this bodily function is its recognition world over as one of the principal medical markers for the presence of life.
However, the importance of your heartbeat extends beyond acting as a notification that you are still alive.
The heartbeat is a rhythmic contraction of the cardiac muscles. These muscles then control the pumping of oxygenated and deoxygenated blood around your body. Consequently, the rate of your heartbeats can be a direct measure of the function and overall health of the organ.
Furthermore, in the multifaceted and interconnected system that is the body, a variance in heart rate levels can be an indicator for a host of conditions, including the adrenaline rush from exercise or fear, hormonal imbalances, psychological issues, or other underlying medical problems.
With heart rate, when you are at rest, less is often always better. Generally, a lower resting heart rate indicates that the organ is performing more efficiently than average. Lower heart rates are usually standard among well-trained athletes and people with high cardiovascular fitness levels.
A lower rate implies that your heart does not have to overexert itself to provide the rest of your body with the minimum required amount of oxygenated blood.

Tachycardia: How High Is Too High
“A resting heart rate that is frequently over 110 or occasionally over 140 can lead to heart damage or heart failure and may need to be treated,” Dr. Santucci says. According to the American Heart Association, the medical term for a heart rate above 100 is tachycardia. Symptoms may include:
- Shortness of breath.
Although the range of normal for a resting and sleeping heart rate is wide, the Mayo Clinic says to let your doctor know if your resting heart rate is consistently above 100, especially if you have any symptoms of tachycardia.
Prevention Via A Healthy Lifestyle
The best way to reduce the risk factors that may lead to complications is a healthy lifestyle. Here are some of the best tips that we suggest to eliminate the risk factors:
- Regular Exercise and Healthy Eating Habits: Exercises keeps your heart rate at an ideal pace. It keeps them pumping enough blood to our body in healthy labour. Eating the right food also plays a significant factor. Try to avoid or minimise the consumption of food that is high on fat, salt, and sugar. Eat more fruits and vegetables instead.
- Weight Management: Maintaining a healthy weight is a proven method in reducing the risks of developing heart disease and other adverse health conditions.
- Moderate Smoking and Acholic Drinks: If you cant quit smoking or drinking, at least try to minimise the consumption gradually. These two factors are potentially dangerous to your overall health.
- Manage your Stress and Get Ample Rest: You can manage your stress through exercise since some techniques help release endorphins which make us feel good. Get enough rest and sleep to improve your waking hours.
- Visit your Doctor Regularly: Physicians are always the best individuals to talk to about your overall well-being. They can formulate a plan for your health and fitness progress better than anyone else.
TIP: A healthy diet and supplements can help maintain optimum condition. for nutritious supplements.

What Are The Symptoms Of Bradycardia
Bradycardia may not cause any symptoms. However, bradycardia may cause you to feel:
- Dizzy or light-headed. You might even experience faints or sudden collapse.
- Short of breath, especially with exercise.
- Very tired.
- A pain in your chest or a thumping or fluttering feeling in your chest .
- Confused or that you are having trouble concentrating.
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 or your chest when youre lying down. Your heart beat may feel:
- too fast or slow
- like its fluttering
- like its thudding, or pounding.
It is not unusual to feel heart palpitations occasionally and mostly they are harmless. However if youre experiencing them on a regular basis, see your doctor.

Other Heart Electrical Issues
The heart communicates by sending electrical signals. For example, one chamber of the heart sends electrical signals to another, telling it how and when to squeeze blood into the next chamber.
The pacemaker helps regulate this electrical system. If the heart is not able to send the correct electrical signals, due to a blockage or heart disease, it can cause bradycardia.
Complete heart block is a type of electrical issue that makes it impossible for electrical signals to travel from the atria the top two chambers of the heart to the ventricles, which are the bottom two chambers. In complete heart block, the top two chambers may have totally different rhythms to the bottom two.
Low Heart Rate : Causes And Symptoms
In this article:
Heart rate is defined as the number of times your heart beats or pumps blood in a minute. Its what people know as pulse, and it is one of the prime indicators of health status.
You need a good heart rate to maintain proper blood supply to all the vital organs in the body. These organs need fresh, oxygenated blood to carry out their functions, which keep you alive.
If your pulse is abnormally low, it usually means your heart is not pumping enough blood to meet your bodys needs, which can lead to generalized weakness and other potentially fatal consequences.

Benefits Of Sleep For Heart Health
According to the Centers for Disease Control and Prevention , getting enough sleep is very important for heart health. During sleep, both your heart rate and your blood pressure go down. Most adults need at least seven hours of sleep to allow the body to rest and repair.
The CDC says that lack of sleep may raise your risk for heart disease, heart attack and stroke. Lack of sleep is also linked to health problems, such as type 2 diabetes and obesity, which can contribute to heart disease.

Is Resting Heart Rate Different By Age
For most of us , between 60 and 100 beats per minute is normal.1 The rate can be affected by factors like stress, anxiety, hormones, medication, and how physically active you are. An athlete or more active person may have a resting heart rate as low as 40 beats per minute. Now thats chill!
When it comes to resting heart rate, lower is better. It usually means your heart muscle is in better condition and doesnt have to work as hard to maintain a steady beat. Studies have found that a higher resting heart rate is linked with lower physical fitness and higher blood pressure and body weight.2
What To Expect At The Doctors
Your doctor may use a variety of diagnostic tools to help diagnose your condition, including:
- Electrocardiogram. Also referred to as an ECG or EKG, this diagnostic tool uses small electrodes to record the electrical activity of your heart. Your doctor can use the information collected to determine if heart abnormalities are contributing to your condition.
- Imaging tests. Imaging can be used to assess if there are any structural abnormalities in your heart that may be contributing to your condition. Possible imaging tests can include echocardiogram, CT scan, and MRI scan.
- Laboratory tests. Your doctor may order blood tests to determine if your condition is caused by something such as an electrolyte imbalance or thyroid disease.
Once a diagnosis is made, your doctor will work with you to develop a plan to treat and manage your condition.
Depending on the findings from the diagnostic tests, your doctor may refer you to a cardiologist. A cardiologist specializes in treating and preventing diseases of the heart and circulatory system.

Potential Causes Of Low Heart Rate
Generally, a slower heart rate when you are at rest is a sign of good health. Bradycardia can result from several positive or neutral causes that shouldnt warrant any worry. Some of these include:
- High fitness levels
- The impact of regular meditative breathing
- A genetic predisposition for a slower heart rate
- The side effect of beta-blockers and other heart-related medications
Do You Know: Bradycardia that stems from the use of beta-blockers and other heart-related medication, is often reversible.
Suppose your heart rate is falling to dangerous levels because of the medication and experiencing symptoms like fatigue, weakness, lightheadedness, shortness of breath, and dizziness. In that case, you should consider stopping the medicine immediately until you consult with your doctor.
In most cases, stopping the medication will immediately reverse the symptoms.
However, in other cases, bradycardia may stem from other severe, more worrying, and potentially more harmful causes like:
- Hypothyroidism and other hormonal and metabolic problems
- Heart attacks
- Sick sinus syndrome, congestive cardiomyopathy, node damage, and other forms of heart disease
In all of these severe cases above, a low heart rate is a cause for concern, as it can signal potentially dangerous or even fatal conditions that require immediate attention. So, how can you tell whether your low heart rate stems from a positive, unthreatening source or a more critical, potentially life-threatening condition?
Postural Orthostatic Tachycardia Syndrome
A person with postural orthostatic tachycardia syndrome may experience an increased heart rate upon standing up. They may also experience dizziness and a drop in blood pressure.
POTS is a condition of the autonomic nervous system. It happens because this system does not properly regulate bodily functions such as blood pressure, heart rate, or breathing.

Normal Resting Heart Rate For Kids
Childrens heart rates are normally faster than those of adults. According to Cleveland Clinic, the normal resting heart rate for a child aged six to 15 is between 70 to 100 beats per minute.
Many factors can affect your resting heart rate, including your level of physical activity. In fact, highly trained athletes can have a resting heart rate of around 40 beats per minute!
Other factors that can affect resting heart rate include:
- Age. You may find that your resting heart rate decreases as you get older.
- Temperature. Your heart rate may increase slightly when youre exposed to hot temperatures.
- Medication side effects. For example, medications such as beta-blockers can lower your resting heart rate.
- Emotions. If youre anxious or excited, your heart rate may increase.
- Weight. People who are obese may have a higher resting heart rate. This is because the heart has to work harder to supply the body with blood.
- 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.

The Conduction System Of The Heart
The heart has its own natural pacemaker made up of a specialized collection of cells in the top chamber of the heart known as the SA node. This generates an impulse that travels through another collection of cells in the middle of the heart known as the AV node. The pathways taken by the impulses are known as the conduction system.
Problems with a low heart rate can be caused by dysfunction of the SA node, the AV node or the conduction system! It gets even more complex. The conduction system of the heart has many nerves attached to it some of these nerves decrease the rate of conduction whereas others increase the rate of conduction. The nerves that decrease the rate of conduction and therefore lower heart rate are known as parasympathetic nerves. An example is when someone vomits this can increase impulses in the parasympathetic nerves and slow the heart rate significantly for a while. This can even lead to passing out, which is known as a vagal event.
A balance of impulse from the sympathetic and the parasympathetic nerves determine a persons baseline heart rate. Interestingly, in experiments where a persons nerve supply is blocked, the heart rate is often higher this would suggest that the parasympathetic nerve impulses that serve to slow the heart rate down are the predominant force under normal resting conditions. This is particularly evident at night when most people have a significant drop in heart rate.
Resting Heart Rate Included In Fitness Calculator
Ulrik Wisløff, a professor at NTNU, the Norwegian University of Science and Technology, has previously argued that good fitness is a very important goal for your health.
Fitness is one of the things that says the most about your health right now and in the future, Wisløff has said.
He and his colleagues have created a fitness calculator based on tests they have done on participants in a study of the population of Trøndelag County, called HUNT3.
The calculator includes resting heart rate, along with age, weight and height, among other factors.

How To Treat Bradycardia
The first step in finding treatment is getting diagnosed, which requires a visit to the doctor. The doctor will measure your heart rate with an electrocardiogram, or EKG/ECG. But if nothing comes up during your visit possibly because you have a minor case of bradycardia that only occurs occasionally the doctor may give you a portable EKG to take with you.
Another handy gadget may be activity tracking features on devices like the Apple Watch. These devices can help track your heart rate 24/7 over many months and years, so it’s easier to detect if and when you have bouts of bradycardia.
After you’ve been diagnosed, treatment depends on the severity of your condition. Steinbaum says borderline or occasional bradycardia may not require medical intervention, and if there are no symptoms, it can be generally monitored. But if you have chronic or persistent bradycardia, she says your doctor may treat it in a few ways.
“If medication side effects are causing the slow heart rate, then the medication regimen can be adjusted or discontinued,” says Steinbaum. “Also, a pacemaker can regulate the heart’s rhythm, speeding up the heart rate as needed.”
Additionally, Duggirala says if hypothyroidism or sleep apnea is causing bradycardia, treatment of the underlying disorder will often help.
What Causes Bradycardia
Bradycardia can be caused by many things. Examples include:
- Changes in the heart that are the result of aging.
- Diseases that damage the heart’s electrical system. These include coronary artery disease, heart attack, and infections such as endocarditis and myocarditis.
- Conditions that can slow electrical impulses through the heart. Examples include having a low thyroid level or an electrolyte imbalance, such as too much potassium in the blood.
- Many types of medicines. Examples include antidepressants, heart medicines, and opioids.

When To See A Doctor
If you or a loved one notices mild to medium symptoms, go to a doctor quickly.
If you or a loved one faints, has chest pains or trouble breathing, call 911.
Tiredness, trouble concentrating, or breathing harder may just seem like part of growing older. But sometimes itâs more than that.
Be sure to tell your doctor about all your symptoms. If you wear out more easily now than you did a month or year ago, let them know.
