text: <unk>  <unk>  is a supraventricular tachyarrhythmia characterized by uncoordinated<unk>  activation leading to an irregularly irregular rhythm and absent P waves on ECG.  It is characterized by palpitations, dyspnea, chest discomfort, syncope, etc. and can be triggered by a number of conditions.  It can be a serious life threatening disorder as the irregular<unk>  rhythm with rate of 400-700 beats/min may transpire into a rapid ventricular rhythm eventually leading to ventricular<unk> ilure.  It can occur in a heart with underlying structural heart defect or in a structurally normal heart.  Treatment of<unk>  depends on hemodynamic status of the patient.  If unstable, rapid DC cardioversion is attempted, otherwise rate control and anticoagulation are the treatment of choice, followed by antiarrhythmic therapy.
