1. Atrial fibrillation (Afib) is a(n) _____ ______ rhythm (refers to cadence) and is marked by an absence of ______.
2. In atrial fibrillation, electrical activity in the atria is referred to as (circle all that are correct):
A. F waves
B. f waves
C. Flutter waves
D. Fibrillatory waves
3. The rates for the f waves in Afib are between:
A. 100 and 200 BPM
B. 150 and 350 BPM
C. 300 and 500 BPM
D. 400 and 600 BPM
4. In atrial fibrillation, the atrial tissue has many ectopic foci firing at the same time. The result is the formation of small depolarization areas or wavelets that each give rise to their own small vector. These vectors form the pattern of the f waves on the ECG strip. True or False.
5. Clinically speaking, the type of f-wave pattern (fine or coarse) is critical to treatment. True or False.
6. In the AV node during atrial fibrillation, there are multiple depolarization waves striking the surface at any one time. These sometimes cancel each other out, leaving only one to conduct the impulse to the ventricles. True or False.
7. Uncontrolled Afib usually occurs at a ventricular rate of _____ _____ _____ BPM.
8. The ventricular response to atrial fibrillation is always irregularly irregular. True or False.
9. Complete AV block can occur in patients with Afib. True or False.
10. Ashman’s phenomenon refers to a pattern where a premature complex is transmitted aberrantly if it occurs after a long cycle. In other words, if you have a(n) ______ cycle length, followed by a(n) ______ cycle length, the complex that belonged to the short cycle will usually be conducted aberrantly.
