Atrial Flutter

ECG Features

Figure 1: ECG Strip[1]

Atrial flutter is a form of supraventricular tachycardia caused by "a re-entry circuit within the right atrium."[2]

Table 1: ECG Characteristics[3]

Clinical Significance[4]

  • The rapid ventricular rate present in atrial flutter causes a decreased cardiac output, which results in symptoms such as palpitations, fatigue, mild, dyspnea, and presyncope.
  • Treatment of symptomatic atrial flutter is similar to treatment of atrial fibrillation. Intravenous calcium-channel blockers or beta-adrenergic blockers can be used to help control the ventricular rate.

ECM Features

  • Transition from Atrial Flutter (red) to Atrial Fibrillation (black)
