Do you sometimes feel like your heart is beating a little strangely? Maybe it feels like your heart is beating loudly and rapidly. Or it feels like your heart is suddenly stopping and then starting again, or it feels like it is beating very slowly. It is normal to feel a little scared when you feel things like this. So today, let's talk about these abnormalities in the rhythm of the heart, which are called dysrhythmia or arrhythmia .
What is Dysrhythmia?
Simply put, dysrhythmia is an abnormal, irregular rhythm of your heart. Now, this can happen in two ways.
One is an abnormal heart rate. That is, your heart beats either very fast (more than 100 beats per minute) or very slow (less than 60 beats per minute) .
The other is the heart rhythm disorder. That is, the rhythm of the heart beats changes. Imagine, our heart starts beating with a small electrical signal. It's like turning on a light switch. Sometimes, this electrical signal may not go through properly because of something blocking it, like scar tissue in the heart. Or, this electrical signal may start prematurely, and you may feel like your heart skipped a beat. Then, after a few seconds of silence, the next heartbeat may feel a little stronger.
If you have a strange feeling like your heart is beating faster or skipping a beat for no apparent reason, you may be wondering, "What's wrong with me?" Some dysrhythmias are not serious, but it's hard to tell until you see a doctor. Some dysrhythmias may require medication, special treatments, the implantation of a device like a pacemaker , or even heart surgery.
What are the main causes of dysrhythmia?
Most of the time, dysrhythmia occurs when the heart rate or rhythm is disturbed for some reason. Here are some of the main reasons that affect this:
- Damage to your heart. For example, it could be due to a heart condition such as coronary artery disease or a weakness of the heart muscle such as cardiomyopathy .
- Problems with the conduction system of your heart.
- Electrolyte imbalances in your blood (e.g., low or high levels of sodium or potassium), hormonal imbalances, or fluid imbalances.
- Some of the medications you take (both prescription and over-the-counter medications).
Also, people with certain medical conditions, such as high blood pressure, heart valve disease, COPD , and sleep apnea (sleep apnea ), are at increased risk of developing dysrhythmia .
What are the symptoms of dysrhythmia?
Sometimes dysrhythmia can be "silent," meaning it doesn't cause any symptoms. In such cases, your doctor may be able to detect this irregular heartbeat by examining you, checking your pulse, listening to your heart, or performing other diagnostic tests.
However, if symptoms do occur, they may be like this:
- Palpitations: A feeling of the heart beating rapidly, like a butterfly fluttering in the chest, like the heart is `flip-flopping`, or like the heart is `racing`.
- Feeling a pounding sound in your chest (`Pounding in your chest`).
- Dizziness or feeling lightheaded.
- Shortness of breath.
- Chest discomfort or pain.
- Feeling weak or extremely tired (`Weakness or fatigue`).
Important: If you experience one or more of these symptoms frequently, it is very important to seek medical advice.
Are arrhythmia and dysrhythmia the same thing?
You may be wondering if the words arrhythmia and dysrhythmia refer to two different diseases. In fact, both words mean the same thing. They both refer to an abnormal or irregular heartbeat. When you search for this, you may see the word arrhythmia used in some places and dysrhythmia in other places.
Then you might think, "Then why are there two words for this? If we had used one word, it would have been fine." The reason for this is a little controversy among doctors that started in 1967. It's a bit of an interesting story.
History of the word "Arrhythmia"
Until 1967, the only word used to describe an abnormal heartbeat was "arrhythmia." In fact, the word dates back much further, to ancient Greece. In the second century AD, a physician named Galen used the word "arrhythmia" to describe a dangerous irregular heartbeat.
Fast forward a little, and in the late 1800s and early 1900s, doctors first began recording and analyzing the heart's electrical impulses. During this important period, French, British, and German researchers all used the word "arrhythmia" to describe abnormal patterns.
"Dysrhythmia" and the controversy between doctors
So, in 1967, someone added something new to the story. An author in the British Heart Journal used the word "dysrhythmia" to mean "bad rhythm" or "faulty rhythm." This author and those who agreed with him argued that the word "arrhythmia" was wrong because it meant "no rhythm." According to their argument, the word "dysrhythmia" was the more accurate word because it meant "a disturbance of rhythm" or "a disorder of rhythm."
This argument got a little complicated when people on both sides started talking about the `linguistic meanings` of words. They looked at the `prefixes` that come at the beginning of words - 'a-' and 'dys-' - and tried to justify their views on what each one meant.
Defenders of the word "arrhythmia" argued that what was important was how the word had been used for centuries. They said that if the ancient Greeks thought "arrhythmia" was the correct word, then that tradition should continue. But proponents of the word "dysrhythmia" insisted that their word was better and more accurate.
From time to time, doctors published editorials and correspondence about this in their professional journals. Those who had staunchly defended the classic term "arrhythmia" viewed the new term "dysrhythmia" as an "upstart" or a "vogue word." They said that the term had no place in the heart.
Although these articles sometimes had a humorous tone, everyone took the issue seriously and told their colleagues to use the same words to avoid confusion. By the early 1990s, the majority opinion seemed to favor the term "arrhythmia." But by then, the term "dysrhythmia" had also become so prevalent in the medical vocabulary that it was impossible to eliminate it.
In 1990, an anesthesiologist noticed that cardiologists and cardiology journals were using only "arrhythmia." So he asked, "So why do anesthesiologists still use "dysrhythmia ?" He argued that while "dysrhythmia" could be used to describe rhythm problems elsewhere in the body, it was not appropriate when talking about the heart. Six months later, another anesthesiologist agreed and said that everyone should use "arrhythmia." That was when the debate was over.
Today, "Dysrhythmia" and "Arrhythmia"
But the story didn't end there. In 2015, a journal that publishes articles about heart arrhythmias published another article arguing that "arrhythmia" was the better word. The authors argued that no one uses the word "arrhythmia" to mean "abnormal heart rhythm," as proponents of the term " dysrhythmia" have long argued. So, this debate has raged for decades.
All this being said, unless you're a doctor reading those magazines, you probably don't even know that this kind of debate is going on. If you feel something strange in your heart, you go to a doctor. Your doctor will probably use the word "arrhythmia."
But then, the way we use words is the way they are. That's why you'll often find the words "Arrhythmia" and "Dysrhythmia" used interchangeably. If you're someone who likes to research word origins, you might want to take a side in this argument. That's up to you. But anyway, the most important thing is to understand how an irregular or abnormal heartbeat can affect your life.
Why do we need to talk to a doctor about this?
A change in your heart rate, especially if it happens suddenly or when you are otherwise healthy, can be very frightening. Also, if someone close to you describes symptoms they are experiencing, such as a racing heart or a pounding heartbeat, you may feel worried and scared. A condition called dysrhythmia can take us by surprise and make us fear the worst.
But remember, most dysrhythmia conditions are treatable and, if detected early, are usually not life-threatening.
Since dysrhythmias can be caused by a variety of conditions, it is important to talk to your doctor about your complete medical history. Also, discuss your family history and risk factors. Your doctor can help you manage your symptoms and provide you with the necessary treatment. Then, you can get your daily rhythm back on track.
Finally, things to remember (Take-Home Message)
Okay, so here are some of the most important things to keep in mind from what we've talked about:
- Dysrhythmia , or arrhythmia, is an abnormal heartbeat. It can be fast, slow, or irregular.
- There can be many reasons for this, including heart disease, electrical signal problems, electrolyte imbalances, and certain medications.
- Symptoms such as chest tightness, dizziness, and difficulty breathing may occur. Sometimes, there may be no symptoms at all.
- "Arrhythmia" and "dysrhythmia" are two words used for the same condition. There's no need to worry about it too much.
- Most importantly: If you feel anything unusual in your heartbeat, don't ignore it and definitely see a doctor.
- Most of the time, these conditions can be controlled with treatment. So don't panic, but don't delay either.
So, take care of your heart. It determines the rhythm of your life!
