A wandering atrial pacemaker (WAP) at 60-100 bpm is also called?

Multiform Atrial Rhythm (MAR)

Atrial fibrillation is controlled when?

overall ventricular rate is less than 100 bpm

T or F; In atrial fibrillation, the AV node attempts to protect ventricles from the hundreds of impulses bombarding it per minute by blocking many of the impulses generated by irritable sites in the atria.

True

T or F; Upon conversion of atrial fibrillation to sinus rhythm, the patient should be observed for signs of a stroke

True

T or F; In atrial fibrillation, fibrillatory waves are referred to as F waves

True

T or F; delivery of electrical current timed with QRS is called defibrillation

False

T or F; The ventricular rhythm of A-fib is irregularly irregular

True
