Question 1
A regular rhythm with narrow QRS complexes, indistinguishable P waves, and a heart rate of 155 would be consistent with
◦ atrial fibrillation.
◦ sinus bradycardia.
◦ supraventricular tachycardia.
◦ ventricular tachycardia.
Question 2
Which of these statements about how sinus arrhythmia differs from wandering atrial pacemaker is TRUE?
◦ Sinus arrhythmia is lethal; wandering atrial pacemaker is benign.
◦ Sinus arrhythmia has a regular rhythm; wandering atrial pacemaker is irregular.
◦ Sinus arrhythmia has a heart rate of less than 100; wandering atrial pacemaker has a rate greater than 100.
◦ Sinus arrhythmia has uniform P wave shapes; wandering atrial pacemaker has at least three different shaped P waves.
