Summary

Lone atrial flutter with 1:1 AV conduction can cause dizzy spells and fainting. Early diagnosis through ECG monitoring is crucial for effective treatment and management of this rare condition.

Area of Science:

  • Cardiology
  • Electrophysiology

Background:

  • Lone atrial flutter is a rare supraventricular tachyarrhythmia.
  • Paroxysmal 1:1 atrioventricular (AV) conduction can complicate atrial flutter, leading to rapid ventricular rates.
  • Misdiagnosis can delay appropriate management.

Observation:

  • Presents three cases of lone atrial flutter with paroxysmal 1:1 AV conduction.
  • Highlights characteristic symptoms including dizzy spells and syncope.
  • Details a case of 18-year misdiagnosis in a 42-year-old patient.

Findings:

  • The mechanism of 1:1 AV conduction in atrial flutter is discussed.
  • Characteristic symptoms of dizzy spells and fainting are emphasized.
  • Diagnostic procedures are outlined.

Implications:

  • Early recognition and diagnosis of this condition are vital.
  • Recommended diagnostic tools include long-term ECG monitoring (telemetry, Holter), exercise-ECG, and esophageal-ECG.
  • Appropriate diagnosis facilitates timely and effective treatment strategies.
