The following techniques aid in the diagnosis of atrial flutter:

  • Electrocardiography (ECG): This is an essential diagnostic modality for atrial flutter

  • Vagal maneuvers: These can be helpful in determining the underlying atrial rhythm if flutter waves are not seen well

  • Adenosine: This drug can be helpful in making the diagnosis of atrial flutter by transiently blocking the AV node

  • Exercise testing: This can be utilized to identify exercise-induced atrial fibrillation and to evaluate the response of the ventricular rate to activity, as well as its interaction with symptoms including those of ischemic heart disease

  • Holter monitor: This can be used to help identify arrhythmias in patients with nonspecific symptoms, to identify triggers, and to detect associated atrial arrhythmias
