You might not give it a second thought until your heart does something abnormal, like it's fluttering, pounding, racing, or skipping a beat. This sensation—termed a heart flutter/palpitations (medically)—suddenly makes you aware of each rhythm shift.
And here’s the real question: Do you feel a fluttering in your chest? Although this feeling can be deeply unsettling, a flutter isn't always cause for immediate alarm. Understanding what is heart flutter and what causes them is crucial. This awareness can make a world of difference in your heart health and guide you to consult a cardiac electrophysiologist if you/your loved ones experience this condition.
This guide unpacks what actually happens when your heart starts acting weird. Let's start by breaking down the most common reasons.
Essentially, your daily habits and overall health significantly contribute to triggering heart flutters. Here are a few common causes of sudden heart fluttering:
This list provides the answer to the key question, “What causes heart flutters?” And correcting these lifestyle problems (usually) tends to help a lot. But if your heart still flutters even after you make changes, it could be a sign of more severe issues—our next area of exploration.
Sometimes, your heart flutters don't subside/go away—no matter what you try. In such cases, you might be dealing with an arrhythmia, or abnormal heart rhythm, where underlying medical conditions can strain the heart and interfere with these vital signals.
The key conditions that can contribute to arrhythmias include:
When these conditions mess with your heart's electrical system, you need a doctor to figure out what's wrong and how to fix it.
Now let's talk about two specific types of serious heart rhythm problems:
Yes, it's considered a serious condition because, similar to AFib, it can lead to major complications. Both conditions result from a “malfunction in your heart's electrical system”—an issue that causes your upper chambers to beat so fast that they can no longer function properly.
With AFL, your heartbeat is fast but still remains organised and regular. In contrast, AFib is characterised by a chaotic, irregular rhythm, making your atria quiver ineffectively. Such fast, uncoordinated activity in both conditions restricts how well your heart can pump blood out of its upper chambers.
Next, let’s look at the signs that may call for professional care.

Most heart flutters aren’t harmful by themselves. But when they are accompanied by other symptoms, that’s when you should be concerned. Get emergency medical help if a flutter comes along with any of these red-flag signs given below:
These signs could signal serious conditions—such as a heart attack/dangerous arrhythmias—because they (often) indicate your heart isn’t pumping sufficient blood to your body and brain. Thus, if you experience a flutter with any of these symptoms, call emergency services immediately.
So, what happens when you visit a doctor for heart flutters? Let's demystify it.
When you consult a cardiologist about heart flutters, they'll recommend assessing your heart function using the following tests:
Wondering what happens next once your condition is diagnosed? Your doctor will create a treatment plan just for you.
Here's how Atrial Flutter is treated
This treatment approach is similar to how other serious arrhythmias are managed and may involve one or a combination of these methods.
