Atrial Fibrillation Rhythm Strip Features

Rate: Very fast (> 350 bpm) for Atrial, but ventricular rate may be slow, normal or fast
Rhythm: Irregular
P Wave: Absent - erratic waves are present
PR Interval: Absent
QRS: Normal but may be widened if there are conduction delays
Not all fibrillatory waves are created equal. The "f" waves can be coarse (majority measure 3 mm or more) or can be fine (majority of waveforms measure less than 3 mm) to almost absent.
Atrial fibrillation is a common type of supraventricular tachycardia (SVT) arrhythmia, characterized by chaotic, quivering atria. These atrial fibrillations result in atrial contractions that are ineffective and out of coordination with the ventricles.
