NCIt definition : An electrocardiographic finding of a supraventricular arrhythmia characterized by
the replacement of consistent P waves by rapid oscillations or fibrillatory waves
that vary in size, shape and timing and are accompanied by an irregularly irregular
ventricular response. (CDISC);
Alternative definition : CDISC: An electrocardiographic finding of a supraventricular arrhythmia characterized
by the replacement of consistent P waves by rapid oscillations or fibrillatory waves
that vary in size, shape and timing and are accompanied by an irregularly irregular
ventricular response.; ACC/AHA: an arrhythmia characterized by uncoordinated atrial myocardium due to multiple
reentry circuits with consequent deterioration of atrial mechanical function. Instead
of intermittently contracting, the atria quiver continuously in a chaotic pattern,
causing a totally irregular often tachycardic ventricular rate;
