Atrial fibrillation is characterized by _____.
A) an erratic, wavy baseline and irregular ventricular rhythm
B) "saw-tooth"- or "picket-fence"-shaped waveforms preceding each QRS
C) one P wave before each QRS and a regular ventricular rate of 60 to 100 beats/min
D) P waves occurring before, during, or after the QRS complex; when seen, they are inverted

Question

Quizplus · Accepted Answer

Atrial fibrillation (AFib) is characterized by an erratic, wavy baseline and an irregularly irregular ventricular rhythm. Because of the quivering of the atrial muscle and because there is no uniform wave of atrial depolarization in AFib, there is no P wave. Instead, you see wavy deflections that are called "fibrillatory waves."
