How would you differentiate a junctional escape rhythm at 40 beats/min from a ventricular escape rhythm at the same rate?
A) It is impossible to differentiate a junctional escape rhythm from a ventricular escape rhythm.
B) The junctional escape rhythm will have a narrow-QRS complex; the ventricular escape rhythm will have a wide QRS complex.
C) The rate (40 beats/min) would indicate a junctional escape rhythm, not a ventricular escape rhythm.
D) The junctional escape rhythm will have a wide QRS complex; the ventricular escape rhythm will have a narrow-QRS complex.

Although junctional and ventricular rhythms are ectopic pacemaker sites, their rhythms can generally be differentiated by the width of their QRS complexes. The junctional escape rhythm will have a narrow-QRS complex; the ventricular escape rhythm will have a wide QRS complex.
