How Would You Differentiate a Junctional Escape Rhythm at 40

question 33

Multiple Choice

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.

Definitions:

Quantitative Predictor Variables

Variables that can be quantified and measured and are used to predict outcomes in statistical analyses.

Indicator Variables

Variables used in statistical models that take the value of 1 if a certain condition is met and 0 otherwise, often used to represent categorical data.

Regression Model

A statistical model used to estimate the relationship between a dependent variable and one or more independent variables.

Stepwise Regression

A method of regression analysis in which the choice of predictive variables is carried out by an automatic procedure.
