Question

Which of the following ekg findings differentiates accelerated idioventricular rhythm from junctional rhythm?

1. accelerated has p waves
2. ventricular rate in accelerated is slower than in junctional
3. accelerated is indicated by an irregular rhythm
4. accelerated has a wide QRS

Answer 1

The EKG finding that differentiates accelerated idioventricular rhythm from junctional rhythm is a wide QRS.

Step-by-step explanation:

The EKG finding that differentiates accelerated idioventricular rhythm from junctional rhythm is 4. accelerated has a wide QRS. In accelerated idioventricular rhythm, the QRS complexes are wide, usually greater than 0.12 seconds. This is because the electrical impulse is originating in the ventricles rather than the atria. In contrast, junctional rhythm has narrow QRS complexes as the electrical impulse originates near the AV node and bypasses the atria.
