Fast or slow
An arrhythmia occurs when the electrical impulses that coordinate the heart's beats don't work properly, causing the heart to beat too fast, too slow, or irregularly. There are different types of arrhythmias, each with its own set of symptoms and potential complications.
For most adults, a rhythm of 60-100 beats per minute is considered normal, although this can go as low as 40 in athletes.
There are a number of factors that increase the risk of developing arrhythmias. These include:
- Age: Over the years, the heart's electrical system can become less efficient, increasing the likelihood of irregular heart rhythms.
- Heart disease: Infarction, heart failure, ischemia, and congenital heart defects damage the heart muscle, leading to rhythm abnormalities.
- Hypertension: High blood pressure puts extra strain on the heart and can lead to changes in its structure and function.
- Diabetes: High blood sugar levels can damage blood vessels and nerves, affecting the heart's electrical system.
- Sleep apnea: Obstructive sleep apnea is also associated with an increased risk of arrhythmias, primarily atrial fibrillation.
- Obesity: Being overweight can contribute to the development of the diseases listed above and put additional strain on the heart.
- Smoking: Tobacco smoke contains harmful chemicals that can damage blood vessels, increase blood pressure, and contribute to heart disease.
- Alcohol: Heavy alcohol consumption can disrupt the heart's electrical signals and increase the risk of developing atrial fibrillation, the most common type of arrhythmia.
- Chronic stress: Stress hormones can stimulate the heart and lead to irregular heart rhythms.
- Genetics: Some types of arrhythmias can be inherited from relatives; for example, prolonged QT interval syndrome or Brugada syndrome.
- Medications: Some medications, herbal supplements, and drugs can affect the heart's electrical activity and increase the risk of arrhythmias.
What arrhythmia feels like
A normal heart rhythm feels like a steady drumbeat. An arrhythmia may cause the heart to feel like it is fluttering or pounding, and you may experience shortness of breath, tightness in the chest, dizziness, or weakness. However, sometimes arrhythmia is asymptomatic, and a person learns about its existence during the next checkup, having made an ECG or undergoing a Holter study.
What is the danger?
Not all arrhythmias threaten health, but some of them require close medical supervision. For example, sinus arrhythmia is fraught with sudden fainting and dizziness. Atrial fibrillation is the cause of blood stasis in the atria, increases the likelihood of blood clots, and can cause stroke, heart attack, heart failure, cardiomyopathy, and other life-threatening pathologies.
How is it treated?
There are many ways to treat arrhythmia, allowing you to restore normal heart rhythm, prevent complications, and reduce the risk of recurrence. The type of treatment your doctor chooses depends on the type and severity of the arrhythmia, your overall health, and other factors. Here are the most common options:
- Medications: Primarily antiarrhythmic drugs, and in some cases blood thinners.
- Cardioversion: This is a procedure used to restore normal heart rhythm in people with types of arrhythmias such as atrial fibrillation or atrial flutter. Cardioversion can be electrical (using a defibrillator) or pharmacologic (using medication).
- Catheter ablation: A minimally invasive procedure in which abnormal heart tissue responsible for the arrhythmia is destroyed.
- Implantation of devices to control and restore normal heart rhythm.
- Surgical procedures: In some cases, surgery may be necessary to treat arrhythmias or underlying heart disease.
And, of course, arrhythmias cannot be managed without certain lifestyle changes. Doctors recommend following a healthy diet low in sodium, saturated fats, and processed foods; getting adequate physical activity; controlling blood pressure, cholesterol, and blood sugar levels; avoiding smoking; minimizing alcohol and caffeine consumption; reducing stress, and getting enough sleep. All of these measures will be useful not only for arrhythmia but also for health in general.
Continuous monitoring is essential to assess the effectiveness of treatment, adjust medications, and address any arrhythmia-related issues. Don't forget to get a check-up regularly and enter your vitals into Ornament!
