Junctional rhythms occur because the electrical impulse comes from the
AV junction instead of the _____________. ( correct answers ) SA Node
What is the normal, inherent rate of the AV Node? ( correct answers )
40-60 bpm
In junctional rhythms, where does the electrical current initiate? ( correct
answers ) the AV junction
What causes the inverted P wave morphology found with junctional
rhythms?
( correct answers ) the reverse flow of electrical activity
Retrograde ( correct answers ) moving backwards
What are the distinguishing characteristics of PJCs? ( correct answers )
causes rhythm to be irregular, P wave may appear before, during, or
after QRS complex
What symptoms will a person have if they have more than four to six
PJCs in one minute? ( correct answers ) chest pain, difficulty
breathing, sweaty, pale
Which rhythm is an early electrical impulse that originates in the AV
junction with an underlying sinus rhythm? ( correct answers )
premature junctional complex
Explain what happens with the electrical conduction system in a
junctional escape rhythm? ( correct answers ) Escape rhythms
occur when the SA Node fails to initiate electrical activity
What is the heart rate for junctional escape rhythm? ( correct answers )
40-60 bpm
What are the distinguishing characteristics of the junctional rhythm?
( correct answers ) regular, occur at similar intervals
What are some symptoms of junctional escape rhythm? ( correct
answers ) low blood pressure, confusion, disorientation
