Ventricular Rhythms

Question 0

What are five ventricular rhythms?

Answer 0

Premature ventricular complexly (PVC)
Ventricular tachycardia
Ventricular fibrillation 
Idioventricular rhythm
Asystole

Question 1

How long is the QRS measurement with ventricular rhythms?

Answer 1

Greater than .12 second

Question 2

Are p waves visible with ventricular rhythms?

Answer 2

No. The atria aren’t being conducted

Question 3

What is the relationship between QRS and T waves with premature ventricular complexes?

Answer 3

T wave extends in opposite direction of QRS complex

Question 4

What is an interpolated PVC?

Answer 4

When the PVC is between two regular beats

Question 5

What is a compensatory pause?

Answer 5

When the PVC takes place of a beat and the surround RRI is doubled the normal RRI

Question 6

What are PVCs an indication of?

Answer 6

Myocardial irritability

Question 7

What are unifocal PVCs?

Answer 7

PVCs that have the same configuration throughout the EKG. They come from a single focus

Question 8

What are multifocal PVCs?

Answer 8

PVCs with two or more configurations along the EKG. There are multiple foci initiating ectopics

Question 9

What is R on T phenomenon?

Answer 9

When the R wave of a PVC falls during the relative refractory period of the T wave

Question 10

What is a PVC couplet?

Answer 10

When two PVCs are attached to each other

Question 11

What is a run of PVCs?

Answer 11

When three or more PVCs follow each other

Question 12

What is grouped beating?

Answer 12

When frequently occurring PVCs occur in pattern with normal beats

Question 13

What is bigeminy?

Answer 13

When every other beat is a PVC

Question 14

What is it called when there’s a repetitive cycle of a PVC followed by three normal beats?

Answer 14

Trigeminy

Question 15

What is quadrigeminy?

Answer 15

A repetitive cycle of four beats followed by a PVC

Question 16

Premature Ventricular Complex

Regularity

Answer 16

Disrupts regularity of underlying rhythm

Question 17

Premature Ventricular Complex

Rate

Answer 17

Depends on underlying rhythm

Question 26

What does ventricular tachycardia look like?

Answer 26

A run of PVCs that last the whole strip

Question 27

What is ventricular tachycardia caused by?

Answer 27

A single irritable focus in the ventricles

Question 28

What is the difference between ventricular tachycardia and ventricular flutter?

Answer 28

The rate | Ventricular flutter is faster (300 bpm)

Question 29

What does ventricular fibrillation look like?

Answer 29

Chaotic, irregular activity with no waves or complexes

Question 30
