A Fluttering Heart Is Not Normal: Understanding Atrial Fibrillation and Atrial Flutter

Your heart may race when you are excited or nervous, but if it flutters for no clear reason, it may signal a heart rhythm disorder. According to Dr Choy Chun Ngok, Consultant Cardiologist in Malaysia at Subang Jaya Medical Centre, a persistently fluttering heart could be a sign of atrial fibrillation or atrial flutter, two often underdiagnosed forms of arrhythmia.

Recognising an Irregular Heartbeat

Patients with atrial flutter or atrial fibrillation may experience between 120 to 160 heartbeats per minute at rest. This unusually high heart rate can go unnoticed until complications such as a heart attack reveal the issue.

Dr Choy explains that both conditions present similar heart arrhythmia symptoms, including:

• Heart palpitations
• Persistent fatigue
• Shortness of breath
  

The key difference lies in the pulse pattern. In atrial fibrillation, the pulse is always irregular, while in atrial flutter, the pulse can be either regular or irregular.

Though not usually fatal on their own, these abnormal heart rhythms can weaken the heart over time, putting it under prolonged stress.

What Causes Atrial Fibrillation and Flutter?

Several risk factors can contribute to the development of arrhythmia, including:

• High blood pressure
• Excessive alcohol consumption
• Use of certain drugs
• Recent heart surgery

Dr Choy adds that even individuals with healthy lifestyles may develop these conditions due to hereditary heart diseases, abnormal heart valves, or other previously unknown factors.

Treatment for Atrial Fibrillation and Atrial Flutter

Initial atrial flutter management and atrial fibrillation treatment typically includes anticoagulant medication to prevent blood clots and reduce the risk of stroke.

In cases where medication is insufficient, a procedure known as ablation may be recommended. This treatment targets the part of the heart responsible for the irregular heartbeat by using either radiofrequency energy or a freezing balloon known as a cryoballoon to eliminate the source of the problem.

Preventing Heart Rhythm Disorders

While these conditions can be difficult to prevent entirely, Dr Choy emphasises the importance of a healthy lifestyle to reduce risk. He recommends:

• Regular physical activity
• A balanced and heart-friendly diet
• Avoiding excessive alcohol intake

Dr Choy reminds us, “A fluttering heart does not always mean you are in love. It could be your heart asking for medical attention.”

Why Heart Check-Ups Matter for Irregular Heartbeat Detection

Early signs of heart disease often go unnoticed until complications occur. That is why routine heart check-ups and screenings are essential for identifying irregular heartbeat and other arrhythmias early.

If left untreated, conditions like atrial fibrillation and atrial flutter can increase the risk of stroke, blood clots, and heart failure. Consulting a skilled cardiologist in Malaysia can ensure you receive a timely diagnosis and effective care.

Need a Heart Rhythm Check-Up?

If you have been experiencing unexplained fatigue, palpitations, or shortness of breath, do not delay seeking help. Identifying abnormal heart rhythms early can prevent serious complications and support long-term heart health.
