New onset Atrial Fibrillation (AF) or Atrial Flutter
If the patient is haemodynamically stable, please confirm AF/flutter with an ECG.
Consider admission if:
New onset AF/flutter within the last 48 hours associated with a pulse of >150 and/or systolic BP < 90mmHg
AF/flutter associated with syncope, chest pain, heart failure and/or shortness of breath
New onset AF/flutter within the last 48 hours in patients who are haemodynamically stable where cardioversion is being considered, please discuss with the Acute GP service
