Which of the following best describes an idioventricular rhythm?


A) Rapid,chaotic rhythm with no pattern or regularity
B) Gradual alteration in the amplitude and direction of the QRS; atrial rate indiscernible; ventricular rate 150 to 250 beats/min
C) Essentially regular ventricular rhythm with QRS complexes measuring 0.12 seconds or greater; atrial rate not discernible; ventricular rate 20 to 40 beats/min
D) Regular ventricular rhythm with QRS complexes measuring less than 0.10 seconds; P waves may occur before,during,or after the QRS; ventricular rate 40 to 60 beats/min

E) All of the above

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.

E) None of the above
F) A) and B)
