Question

Quizplus · Accepted Answer

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 and 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.
