Atrial Fibrillation and Atrial Flutter

Bianca Lee, DO, MS and Youhua Zhang, MD, PhD Reviewed 06/2019
 


BASICS

This topic covers both atrial fibrillation (AFib) and atrial flutter (AFlut). 

DESCRIPTION

  • AFib: paroxysmal or continuous supraventricular tachyarrhythmia characterized by rapid, uncoordinated at...

DIAGNOSIS

HISTORY

Symptoms vary from none to mild (palpitations, light-headedness, fatigue, poor exercise capacity) to severe (angina, dyspnea, syncope). 

PHYSICAL EXAM

  • AFib: irregularly irregular heart ...

TREATMENT

MEDICATION

  • Two primary issues in the management of AFib and/or AFlut: decisions on heart rate control (control ventricular rate while allowing AFib to continue) or rhythm control (terminate A...

ONGOING CARE

Many patients may benefit from elective expert consultation. In patients with no significant symptoms, if ventricular rate control or sinus rhythm is easily achieved and the choice of thr...

CLINICAL PEARLS

  • Primary decision in persistent AFib is rate control or rhythm control. Younger patients often do better with a rhythm control strategy, whereas older patients often do well with rate c...
