Atrial Fibrillation Atrial Flutter Atrial Fibrillation (Afib) Afib stands for atrial Fibrillation (AF) Atrial Fibrillation is a type of arrhythmia or abnormal heart beat and is a major cause of stroke. Atrial Fibrillation is an irregularly irregular and often very rapid heart rhythm that begins in heart upper chambers (Atria). in which the upper chambers of the heart (atria) beat out of coordination with the lower chambers of the heart (ventricle). ATRIAL FIBRILLATION FINDINGS ON ECG Findings Irregularly irregular QRS Complex P wave absent / no visible P wave present Heart beat range (100bpm - 160bpm) Types of Atrial Fibrillation There are three main types of atrial fibrillation.... Paroxysmal atrial Fibrillation Persistent atrial fibrillation Long standing persistent atrial fibrillation Paroxysmal Atrial Fibrillation It's episodes occurs less than one week and usually stops on its own without treatment. Persistent Atrial Fibrillation It's episodes occurs more than one we
