Is your heart beating slowly? Let's talk about bradyarrhythmia!

Do you sometimes feel like your heart is beating a little too slowly? Or do you suddenly feel tired, dizzy, and maybe even have trouble breathing? These may be because your heart rhythm is a little too slow, which means your heart rate is slowing down. We are going to talk about such a condition today, which is called bradyarrhythmia in medical science.

What exactly is Bradyarrhythmia?

Simply put, bradyarrhythmia is an irregular heartbeat, meaning your heart beats too slowly. Normally, a healthy adult's heart beats between 60 and 100 times per minute when at rest. However, a person with bradyarrhythmia has a heart rate that is slower than 60 beats per minute.

Now you might be thinking, "Oh, so my heart is beating so fast, is that a disease?" It's not always like that. Healthy, young people, athletes, who exercise well, naturally have a slightly slower heart rate. It's a sign of their health. And even when we're sleeping, our heart rate slows down a little. That's normal.

However, bradyarrhythmia is a condition in which the heart's rhythm becomes irregular and slow due to a medical condition, heart disease, or a defect in the heart's electrical system . That's what we need to be concerned about.

What is the difference between Bradyarrhythmia and Bradycardia?

These two words sound a bit similar, don't they? They both refer to a slowing of the heart rate.

• Bradycardia is simply a resting heart rate of less than 60 beats per minute. This can happen to even healthy people, as mentioned earlier.
• Bradyarrhythmia is a condition in which the heart rate slows down due to an irregular heartbeat (arrhythmia) . That is, due to some problem, the heart rhythm is disrupted, resulting in a slow heartbeat.

Do you understand the difference? There's a difference between just a slow heart rate and a slow heart rate due to a rhythm problem.

What are the main types of bradyarrhythmia?

Bradyarrhythmia can come in many forms. That is, there are several types depending on the heart problems that cause it. Each type results in the heart beating slowly. Let's look at the main types.

1. Sinus node dysfunction

This is sometimes called sick sinus syndrome . Have you heard that the heart has a natural pacemaker? That's what the sinus node (Sinoatrial node or SA node) is called. It's like the light switch in our house, the electrical signal that makes the heart beat starts here. So if this sinus node isn't working properly, if it can't send the electrical signal properly, the heart rate slows down.

• Some diseases, such as hypothyroidism, can impair the function of this sinus node.
• Or this condition can occur as you get older. Sometimes, the cause cannot be found.

2. Heart block

It's like a traffic jam on a road. If there's an obstruction in the path of the heart's electrical signals, those signals don't travel properly. This obstruction can cause the electrical signals to stop completely, slow down, or even skip a beat. This is called heart block .

3. Bradycardia/tachycardia syndrome

This is a bit complicated. What happens here is that the heart sometimes beats very slowly (bradycardia) and sometimes very quickly (tachycardia) due to a malfunction in the sinus node. This means that the heart beats alternately slowly and rapidly. A condition called atrial fibrillation (AFib) is an example of this type of syndrome.

Why does bradyarrhythmia develop? What are the causes?

Most of the time, these types of heart rhythm problems, including bradyarrhythmia, are caused by either heart disease or damage to the heart. Let's look at some of the main causes:

• Changes in the heart's electrical system with aging: Just like a machine, small errors occur as it ages.
• Coronary artery disease: This means blockage of the arteries that supply blood to the heart.
• Heart defects.
• Certain medications used for heart disease: For example, medications such as beta-blockers .
• Imbalances in the body's metabolic process: As mentioned earlier, decreased thyroid function (Hypothyroidism) .
• Accidents or damage to the heart: For example, due to a heart attack.

What are the symptoms of someone with Bradyarrhythmia?

What happens when the heart beats slowly? The amount of blood and oxygen that gets to the entire body, especially the brain, decreases. That's what causes these symptoms.

Think about it, if you slow down the water pump, it will slow down the filling of the tank. When the heart beats slowly, it pumps less blood throughout the body.

See if you feel these things too:

• Dizziness.
• Rarely, fainting (syncope).
• Feeling tired all the time (Fatigue).
• Difficulty breathing, feeling like you're suffocating (shortness of breath).
• Weakness.

If you have one or more of these symptoms, especially if they occur frequently, you should definitely see a doctor.

How does a doctor accurately diagnose bradyarrhythmia?

When you see a doctor, he or she will first ask you about your symptoms and then perform a physical exam. To determine if you have a heart rhythm problem, your heart rate will be measured and monitored. This may include one or more of the following tests:

• ECG test (Electrocardiography - EKG/ECG): This is often the first test done. It records the electrical activity of the heart. It is a painless test that can be done in a few minutes.
• 24- or 48-hour ECG (Portable ECG device): Sometimes, a heart rhythm problem may not be apparent at the time of your visit to the doctor. Therefore, you may be asked to wear a small device (like a Holter monitor) for 24 or 48 hours. This can continuously record your heart rhythm while you go about your daily activities.
• Exercise stress test: In this test, you are made to run or walk on a treadmill, increasing your heart rate, and then observing how your heart rhythm changes during that time.
• Echocardiography (Echo): This is like a scan of the heart. It can look at things like the heart valves, how the chambers pump blood, and the shape of the heart.
• Electrophysiologic testing (EP study): This is a more complex test. It helps to find out in great detail how the heart's electrical system is working.

These tests are what help a doctor determine whether you have bradyarrhythmia, if so, what type it is, and what the cause is.

How is Bradyarrhythmia treated? How is it managed?

Don't worry, there are treatments for this condition. The treatment depends on the cause of the bradyarrhythmia and how severe it is.

• Treating the underlying condition: Sometimes this is caused by another condition. For example, if it is due to an underactive thyroid gland (hypothyroidism) , treating that can help the heart rate return to normal.
• Pacemaker implantation: If your bradyarrhythmia is caused by changes in the heart's electrical system, your doctor may recommend a pacemaker . This is a small electronic device that sends electrical signals to the heart, helping it beat at a steady, healthy rate. It's like an outside helper when the heart's natural pacemaker fails.

What can we do to prevent this bradyarrhythmia?

Although it cannot be completely prevented, there are things we can do to reduce the risk.

• Getting proper treatment for underlying health conditions: For example, it is important to control things like thyroid problems, high blood pressure, and diabetes.
• Keeping your heart healthy: This is the most important thing.
• Follow a healthy diet: Eat foods low in oil, salt, and sugar, and high in fruits and vegetables.
• Limit alcohol consumption: It is best to reduce it as much as possible.
• Maintain a healthy weight: Maintain a weight that is appropriate for your height.
• Be physically active: Walking and exercising for at least 30 minutes a day is very good.
• Avoid smoking and using tobacco products completely.

By following these steps, you can protect yourself from not only bradyarrhythmia, but also many other diseases.

What is the health status of someone with Bradyarrhythmia? (Prognosis)

This is a question that many people ask. If left untreated, bradyarrhythmia can cause serious health problems. It can also cause accidents due to things like dizziness and fainting.

However, with the right treatment, you can restore your heart rhythm, reduce the risk of complications, and live a normal life. That's why it's important to see a doctor as soon as possible if you have symptoms.

What time should I see a doctor?

If you have any of the following symptoms, you should definitely talk to a doctor about them:

• Chest pain or discomfort.
• Difficulty breathing.
• Dizziness or fainting.
• Fainting.
• If you feel very tired.

If any of these occur frequently, be sure to seek medical advice.

What are the important questions to ask the doctor?

When you see a doctor, you can ask questions like these to get a clear understanding of your condition:

• How do I know if my heart rate is really low?
• Is my heart rate low enough to cause health problems?
• Do I need to take medication to control this heart rhythm problem?
• Will I need a pacemaker to restore my heart rhythm?

It is very important to ask questions like these to gain a better understanding of your situation.

So, let's remember what we talked about as a summary (Take-Home Message)

Bradyarrhythmia is an irregular heartbeat, meaning the heart beats less than 60 times per minute. This can be caused by a number of factors, including age, heart disease, and certain medications. Symptoms can include dizziness, fatigue, and shortness of breath.

The best thing to do for this condition is to get proper medical tests done, find the cause, and get the necessary treatment (such as medication or a pacemaker). Then you can restore your heart rhythm and live a healthy life. Therefore, if you have symptoms like these, don't be afraid to see a doctor. Then you can know everything properly and do what is necessary.
