Exam 9: Introducing the Junctional Rhythms

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

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?

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:

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

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

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

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

The intrinsic firing rate of the AV junction is:

Occurrences of premature junctional contractions are often life-threatening.

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:

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

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

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