Do you sometimes feel like your heart is beating faster than usual? Or does your heartbeat seem to be irregular? Maybe you feel something strange, a tightness in your chest? These may not be just any symptoms. Today, we will talk about a specific condition related to heart rhythm that can cause these symptoms.
What is Atrial Arrhythmia?
Simply put, atrial arrhythmia is an irregular heartbeat. This occurs when the upper chambers of the heart (called the atria ) do not work in harmony with the lower chambers ( the ventricles ). Think of it like each member of a band playing in unison. What happens then? The heart either starts beating too fast or too slow. This causes the blood to flow poorly throughout the body, which means that blood circulation is impaired .
What are the main types of atrial arrhythmia?
There are many different types of this condition. There may be slight differences between them. Let's look at some of the main types.
1. Atrial Fibrillation (Afib)
This is a very common type of arrhythmia. In Afib , the upper chambers of the heart (atria) beat very fast, irregularly, and without any order. In other words, they just flutter. If this is not treated properly, it can lead to dangerous conditions such as stroke .
2. Accessory Pathway Tachycardia / Bypass Tract Tachycardia
This is when an extra electrical pathway is created between the upper chambers (atria) and the lower chambers (ventricles) of the heart. Normally, electrical signals travel through what is called the AV node . However, if the electrical signals travel too fast along this extra pathway, the heart beats too fast. Wolff-Parkinson-White syndrome is a good example of this.
3. Atrial Flutter
This is when the electrical signals in the upper chambers of the heart (atria) become too rapid. This causes the atria to beat too fast. This condition can occur together with heart attack, heart failure, and structural heart defects.
4. Atrial Tachycardia (AT)
Tachycardia is a rapid heartbeat. In AT , an electrical signal starts in the wrong place in the upper chambers of the heart (atria), causing the heart to beat rapidly.
5. AV Nodal Re-entrant Tachycardia (AVNRT)
This occurs when there is more than one way for electrical signals to pass through the AV node . AVNRT is a type of paroxysmal supraventricular tachycardia (PSVT) , a condition in which the heart beats rapidly but irregularly. It can come on suddenly and go away just as quickly.
6. Premature Atrial Contractions (PACs)
This is when the heart beats prematurely, which means it beats prematurely. These are usually harmless and do not require treatment .
How common is atrial arrhythmia?
Heart rhythm disorders are actually more common than you might think . Millions of people around the world suffer from some form of arrhythmia. The most common of these is atrial fibrillation (Afib), which we talked about earlier. Those small, harmless changes in heart rate, or PACs (Premature Atrial Contractions) , are something that almost all of us will experience at some point in our lives.
Why does this atrial arrhythmia occur?
The main cause of this condition is abnormal electrical signals that start in the upper chambers of the heart (atria). These abnormal signals can be hereditary (meaning someone in your family has them and you can get them too), or they can be caused by other health problems or heart disease.
Due to health problems and heart disease:
- Anemia , which means a lack of red blood cells.
- Cardiomyopathy is a disease of the heart muscle.
- Diabetes (Diabetes Mellitus) .
- Heart damage from a heart attack or previous heart attack.
- Heart disease , coronary artery disease (CAD) , and heart failure .
- High blood pressure (Hypertension) .
- Lung-related diseases, for example , Chronic Obstructive Pulmonary Disease (COPD) .
- Structural problems of the heart, for example, heart valve disease .
- Thyroid problems, especially hyperthyroidism .
Due to lifestyle factors:
These things can also increase the risk of atrial arrhythmia:
- Dehydration of the body .
- Drinks and foods containing caffeine (like tea, coffee).
- Some people may experience heart palpitations after eating foods high in fat, sugar, or carbohydrates.
- Certain medications, for example , pseudoephedrine, which is found in some cold medicines.
- Excessive alcohol consumption .
- Overweight and obesity .
- Severe stress and anxiety .
- Hormonal changes, for example during menopause or during pregnancy. Heart palpitations during pregnancy are very common and usually harmless.
- Smoking and use of tobacco products .
How do you know if you have Atrial Arrhythmia? What are the symptoms?
Sometimes this condition can be present without any symptoms. However, here are some of the most common symptoms:
- It feels like your heart is beating very fast but in one rhythm . Your chest is pounding, as if you've just run.
- Irregular heartbeat . It may feel like your heart skipped a beat, stopped beating, suddenly beat faster, or beat slower.
- Chest pain , discomfort, or tightness.
- Shortness of breath .
- Feeling dizzy or confused.
- Fainting / syncope .
- Extreme fatigue , a feeling of lifelessness.
- Feeling of pounding in the chest, throat, or neck (heart palpitations) .
- Swelling (edema) of the limbs, especially the legs, ankles, and feet .
How do doctors diagnose this condition?
After listening to your symptoms and listening to your heart, your doctor will first order a blood test . This is usually a complete blood count (CBC) . This checks for anemia, vitamin deficiencies, or thyroid problems.
Then, the next test you'll need to do is an electrocardiogram (EKG or ECG) . This involves attaching a series of sensors to your skin to record your heart's electrical activity, or heart rate. This can be done in a doctor's office and takes about 15 minutes.
Imagine that you didn't have that irregular heartbeat when you went to the doctor. If that were the case, it wouldn't be recorded on the EKG. In such a case, the doctor may ask you to use an ambulatory monitor , for example , a Holter monitor . This is a small, portable device. You have to wear it for about a week. During this time, your heartbeat and any irregularities will be recorded on it.
What are the treatments for atrial arrhythmia?
If you are diagnosed with an arrhythmia, you will be referred to a cardiologist . Treatment will depend on your overall health and the type of arrhythmia.
Changes in lifestyle and eating habits:
Many types of arrhythmia can be controlled with these simple changes:
- Stop or limit alcohol, caffeine, and certain medications (e.g., cold medicines containing pseudoephedrine).
- Drink plenty of water to prevent dehydration.
- Asking for help to reduce stress and anxiety, practicing relaxation exercises and deep breathing techniques .
- If you are obese, losing weight and maintaining a healthy weight is important .
- Completely stop smoking and using tobacco products .
Medical treatment:
Some types of arrhythmia require medical treatment in addition to lifestyle changes. If you have more than one type of arrhythmia, you may need more than one treatment. Here are some of the main treatments:
- Catheter Ablation: This is not as major as surgery. It destroys a small piece of tissue inside the heart that is sending out irregular electrical signals. This stops the abnormal rhythm.
- Devices: Sometimes a device such as an implantable cardioverter-defibrillator (ICD) , subcutaneous ICD, or pacemaker may need to be implanted in the heart to control the heart's rhythm.
- Electrical Cardioversion: This involves administering safe electrical shocks (jolts) to the heart, stopping the abnormal rhythm and restoring it to a normal rhythm.
- Medications: There are medications that are given to keep the heart rhythm regular or prevent irregularities (arrhythmia medications). Also, people with Afib may be given blood thinners to reduce the risk of stroke.
How to reduce the risk of atrial arrhythmia?
It may not be possible to completely prevent this, but we can reduce our risk by staying healthy and making smart decisions.
- Following a heart-healthy diet .
- Exercise well and stay active .
- If you are obese, losing weight and maintaining a healthy weight is important .
- If you have high blood pressure (hypertension), control it.
- Controlling cholesterol levels .
- Talk to your doctor and make a plan to quit smoking and using tobacco products.
If you have heart disease or other health problems that increase your risk of this arrhythmia, talk to your doctor about it. He or she will explain what other steps you can take.
What is the outlook for someone with Atrial Arrhythmia? (Outlook)
This really depends on a number of factors. The type of arrhythmia you have and your overall health can all play a role. Many people can manage their symptoms with lifestyle and dietary changes. Treatments for atrial arrhythmia can help you live a healthier life overall . The most important thing is to see your doctor regularly to check on your heart health and work with him or her to stay healthy.
When should you see a doctor about atrial arrhythmia?
If you have any concerns about your heart rate, or if you have any of the symptoms we've discussed, be sure to see a doctor . If you already know you have atrial arrhythmia, see your cardiologist regularly.
Symptoms that require urgent attention:
If you have these symptoms , seek medical advice immediately :
- Chest pain .
- Frequent fainting spells .
- Sudden or unexplained fatigue or exhaustion .
- Swelling in your legs, feet or ankles .
