A client's electrocardiogram tracing shows a sawtooth pattern with F waves. The nurse realizes this client is demonstrating:
1. atrial flutter.
2. atrial fibrillation.
3. premature atrial contractions.
4. atrial tachycardia.
1
Atrial flutter is characterized by F waves that occur in a characteristic sawtooth pattern. Atrial fibrillation is characterized by coarse waves with the baseline between the QRS complexes as being rough and uneven. Premature atrial contractions occur when an electrical impulse is generated in an area of the atria outside of the SA node. Atrial tachycardia is three or more premature atrial contractions. Neither premature atrial contractions or atrial tachycardia have an F wave on the tracing.
