Exam 9: Introducing the Junctional Rhythms

In the junctional rhythm, the electrical impulse is most often traveling away from the ________ electrode.

When the SA node fails to generate an impulse or the rate of impulse generation falls below that of the AV node, the resulting rhythm is called a:

A pause that occurs after an ectopic beat in which the SA node is unaffected and the cadence of the heart is uninterrupted is called:

Junctional escape rhythm is sometimes called a junctional bradycardia when the rate falls below:

The direction of the "P" wave in a junctional rhythm most often has a(n) ________ deflection from the isoelectric line.

A ________ rhythm is one that is observed to start and/or end abruptly.

The intrinsic firing rate of the AV junction is:

When a patient is having complaints such as shortness of breath, chest pain, low blood pressure, etc., these are referred to as:

Which of the following can cause junctional escape beats or junctional escape rhythm?

________ rhythms are those that are initiated in the area of the AV junction.

When the junctional firing rate exceeds 100 beats per minute, it is referred to as:

When the electrical impulses travel in a backward direction, this is known as:

Occurrences of premature junctional contractions are often life-threatening.

A pause that causes the underlying rhythm to be interrupted is:

A rhythm that has increased automaticity in the AV junction, causing the junction to discharge impulses at a rate faster than its intrinsic rate, is called:
