Question 5 of 5
A patient who reports dizziness and who has absent P waves, wide QRS complexes, and a heart rate of 38 beats/min on an ECG is most likely in which rhythm?
Correct Answer: C
Rationale: A ventricular escape rhythm originates in the Purkinje fibers, has a rate of 15 to 40 beats/minute, and is characterized by a wide QRS complex. An important clue to identifying escape rhythms is the absence of normal P waves and PR intervals. The rhythm involved in third-degree heart block includes regularly occurring P waves. Junctional tachycardia has a heart rate between 70 to 140 beats/minute. P waves are preceding, following, or buried in the QRS complex. Sinus bradycardia has a normal pattern on the ECG, but with a rate of less than 60 beats/minute.
