WebA characteristic sign of A-Fib is the absence of a P wave in the EKG signal.

The normal duration (interval) of the QRS complex is between 0.08 and 0.10 seconds. ... WebIn most cases, the P-wave is not visible because when impulses are discharged from the junctional area, atria and ventricles are depolarized simultaneously and ventricular depolarization (QRS) dominates the ECG. If the atria are activated prior to the ventricles, a retrograde P-wave will be visible in leads II, III and aVF prior to the QRS complex.
