Medical Term for Heart Flutter

Introduction

The term heart flutter generally refers to an abnormal heart rhythm, also known as arrhythmia. A specific type of arrhythmia associated with rapid, irregular heartbeats is called atrial flutter.

What Is Atrial Flutter?

Atrial flutter is a condition where the heart's upper chambers (atria) beat too quickly, leading to an irregular and often fast heartbeat. It is caused by abnormal electrical circuits in the atria.

Symptoms of Atrial Flutter:

  • Palpitations (feeling of a racing heart)
  • Shortness of breath
  • Dizziness or lightheadedness
  • Fatigue
  • Chest discomfort

Causes and Risk Factors:

Atrial flutter may occur due to: - High blood pressure - Heart disease (e.g., coronary artery disease, heart failure) - Previous heart surgery - Thyroid disorders - Chronic lung disease - Excessive alcohol or caffeine consumption

Diagnosis and Treatment

Doctors diagnose atrial flutter using: - Electrocardiogram (ECG) – records the heart’s electrical activity. - Holter monitor – records heart activity over 24-48 hours. - Echocardiogram – uses ultrasound to assess heart structure and function.

Treatment Options:

  • Medications – Beta-blockers, calcium channel blockers, or antiarrhythmic medications.
  • Catheter ablation – A minimally invasive procedure to destroy abnormal heart tissue causing atrial flutter.
  • Cardioversion – A controlled electrical shock to restore normal heart rhythm.

Conclusion

Atrial flutter is a manageable condition with proper diagnosis and treatment. If you experience symptoms of heart flutter, seeking medical advice is important to avoid complications like stroke or heart failure.
