  • Atrial Flutter/Fibrillation

  • Atrial FlutterReentrant type arrhythmia

  • Atrial FlutterTypical atrial rate is about 300 / min

  • Atrial FlutterVentricle rate is closer to 150, 100 or 75 beats/min2:1, 3:1 and 4:1

  • Atrial FlutterCausesSymptomspalpitations, light-headedness, syncopeFormation of thrombi
