Atrial Flutter Rate

Introduction

Atrial flutter is a type of arrhythmia where the atria (the upper chambers of the heart) beat too fast, usually at a rate of 250-350 beats per minute , but not all of these impulses reach the ventricles. This causes an irregular heart rhythm.

How is the Heart Rate Affected?

  • Atrial Rate : Typically around 250-350 bpm .
  • Ventricular Rate : Usually slower because not all atrial impulses are conducted through the AV node. The ventricular rate is usually 75-150 bpm , depending on AV node conduction (e.g., 2:1, 3:1 block).
  • Symptoms : Atrial flutter can cause palpitations, dizziness, fatigue, and even shortness of breath.

Risk Factors and Causes

  • High blood pressure (hypertension)
  • Heart failure
  • Valvular heart disease
  • Chronic lung disease
  • Excessive alcohol or stimulant use
  • Previous heart surgery

Diagnosis

  • Electrocardiogram (ECG) : Shows a saw-tooth pattern typical of atrial flutter.
  • Holter Monitor : Helps capture intermittent flutter episodes.
  • Echocardiography : Evaluates heart structure and function.

Treatment Options

1. Rate Control

  • Beta-blockers (e.g., metoprolol)
  • Calcium channel blockers (e.g., diltiazem)

    2. Rhythm Control

  • Cardioversion (electrical or pharmacological)

  • Antiarrhythmic drugs (e.g., amiodarone)

    3. Ablation Therapy

  • Catheter ablation is often the definitive treatment to destroy abnormal electrical pathways.

    4. Anticoagulation

  • Necessary if atrial flutter is persistent to reduce stroke risk.

Conclusion

Atrial flutter is a serious but treatable arrhythmia. Proper medical evaluation and treatment are needed to control the heart rate, prevent complications, and improve quality of life.
