Ekg Ch. 5 Junctional Rhythms Test

Front 1

False

Back 1

An accelerated junctional rhythm is a potentially life threatening dysrhythmia. True/false?

Front 2

Ventricular rate less than 40bpm

Back 2

The term junctional bradycardia is used to describe a rhythm that is junctional in origin with what ventricular rate?

Front 3

Junctional escape beat

Back 3

A beat originating from the AV junction that appears later than the next expected sinus beat is called a what?

Hint 3

Later than=escaping

Front 4

P wave

Back 4

The primary waveform used to differentiate PJCs from PACs is the what?

Front 5

Early, before the next expected sinus beat

Back 5

Where in the cardiac cycle does the PJC occur?

Hint 5

Premature, early

Front 6

Accelerated junctional rhythm

Back 6

Rate: 90 bpm

P wave: none

QRS: skinny

Front 7

Sinus rhythm with PJCs

Back 7

Hint 7

Some inverted p waves, before every skinny qrs

Front 8

Accelerated junctional rhythm

Back 8

Front 9

Slowing of the rate of the heart's primary pacemaker

Back 9

Why does a junctional escape rhythm occur

Front 10

AV node and non branching portion of the bundle of His

Back 10

What does the atrioventricular (av) junction consist of?

Front 11

0.12 seconds

Back 11

In rhythms originating from the av junction, the qrs duration is typically how many seconds or less? (Unless an intraventricular conduction delay exists)

Front 12

Inverted

Back 12

If seen, the p wave of a rhythm originating in the AV junction will appear __ in lead II

Front 13

61-100 bpm

Back 13

An accelerated junctional rhythm is identified by a regular ventricular response occuring at what bpm rate

Front 14

An organized rhythm on the cardiac monitor (other than vt) although a pulse is NOT present

Back 14

What is meant by the term "pulseless electrical activity" (PEA)

Hint 14

Pulseless=pulse not present

Front 15

Junctional escape rhythm will have NARROW qrs complex....Ventricular escape rhythm will have a WIDE qrs complex

Back 15

How would you differentiate a junctional escape rhythm at 40 bpm from a ventricular escape rhythm at the same rate

Hint 15

Important question!

Front 16

Ventricular tachycardia

Back 16

A rapid, wide qrs rhythm associated with pulselessness, shock, or CHF should be presumed to be:

Hint 16

Fast and wide

Front 17

A run of ventricular tachycardia

Back 17

The term for three or more premature ventricular complexes (pvc) occuring in a row at a rate of more than 100 bpm is:

Hint 17

Three pvcs; more than 100 bpm

Front 18

Ventricular depolarization

Back 18

What does the qrs complex represent?

Front 19

Idioventricular rhythm

Back 19

This ectopic rhythm is essentially a regular ventricular rhythm with qrs complexes measuring greater than 0.12, atrial rate not discernible, ventricular rate 20-40 bpm

Front 20

20-40 bpm

Back 20

What is the rate of an idioventricular rhythm?

Front 21

Accelerated idioventricular rhythm

Back 21

This ectopic rhythm is essentially a regular ventricular rhythm with qrs complexes measuring more than 0.12 sec, atrial rate not discernible, ventricular rate 41-100 bpm

Front 22

PVC - premature ventricular complex

Back 22

This ectopic rhythm presents a wide, bizarre complex

Front 23

Different types of ectopic ventricular rhythms

Back 23

1. PVC (interpolated)

2. PVC (uniform, ventricular quadrigeminy)

3. PVC (multiform)

Front 24

Different types of ventricular rhythms
