  • IntroductionPVSTatrial rate = 140-250 cycles /minAtrial flutteratrial rate = 250-350 cycles/minF wavessawtooth shapeAtrial fibrillationatrial rate = 350-600 cycles/minf waves

  • 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

  • Atrial FlutterTreatmentspontaneousoxygen treatment (hypoxemic patients)drugs (beta blocker, Ca channel blocker, digitalis, antiarrhythmia drug)synchronized electrical cardioversionpacing wireRF catheter ablation
