Question

When a wandering atrial pacemaker rhythm increases to a rate faster than 100 beats/minute, the resulting arrhythmia is called: Wolff-Parkinson-White syndrome. Multifocal atrial tachycardia (MAT). Atrioventricular reentrant tachycardia (AVRT). Atrioventricular nodal reentrant tachycardia (AVNRT).

Which of the following is true regarding premature atrial complexes (PACs)? PACs are uncommon. PACs have an upright P wave before the QRS complex. The P wave of a PAC is smooth and rounded, resembling those from the sinoatrial (SA) node. PACs disrupt the patient's underlying rhythm, occurring later than the next expected beat from the SA node.

ECG characteristics of atrial flutter include: An upright P wave before each QRS complex. APR interval measuring more than 0.20 seconds. An atrial rate that often ranges from 240 to 300 beats/min. QRS duration that is longer than 0.12 seconds in duration.

Which of the following statements is true regarding AFib? Persons with AFib are at increased risk of stroke. Recent research has confirmed that AFib is not hereditary. Developing AFib usually improves the person's cardiac output. AFib results when a single irritable site within the atria emits impulses at a rapid rate.
