Which atrial dysrhythmia has a cardiac complex that occurs too soon and may have abnormal P waves, but other than being ''early,'' has no other abnormal features?

Question

Quizplus · Accepted Answer

PACs occur when an ectopic focus in the atria fires an impulse too soon, resulting in an abnormal premature heartbeat that may have abnormal P waves but otherwise does not have any other abnormal features. Atrial flutter and fibrillation are characterized by rapid and irregular atrial rhythms with distinct differences in the cardiac complexes, and wandering atrial pacemaker is a rhythm where the pacemaker site in the atria shifts between several locations resulting in variable P wave morphology.
