Ventricular tachycardia and Ventricular fibrillation

Question 1

Ventricular tachycardia

Answer 1

a fast dysrhythmia that arises from the ventricles.

Question 2

Ventricular tachycardia rate and rhythm

Answer 2

100-250 bpm, regular

Question 3

Ventricular tachycardia P waves

Answer 3

hidden in QRS

Question 4

Ventricular tachycardia PR

Answer 4

absent

Question 5

Ventricular tachycardia QRS

Answer 5

wide and bizzare

Question 6

Ventricular tachycardia ST

Answer 6

depressed or elevated

Question 7

Ventricular tachycardia T

Answer 7

opposite of R

Question 8

Ventricular tachycardia QT

Answer 8

prolonged

Question 9

Ventricular tachycardia causes

Answer 9

it is increased Myocardial irritability that is causes by enhances automaticity (from MI or ischemia), Re-entry loops from the purkinje system, or from PVC’s that are R on T. Stimulant drugs, Digoxin, hypokalemia and acid-base imbalance may also cause.

Question 10

Ventricular tachycardia effects

Answer 10

always significant. compromised CO and decreased coronary and cerebral perfusion.

Question 11

Ventricular tachycardia treatment

Answer 11

Maintain airway, give O2, place IV line. If stable can treat with amiodarone, procanamide or stall. If unstable, do cardioversion. If pulseless, treat as though it is V-Fib.

Question 12

Ventricular fibrillation

Answer 12

result of chaotic firing of multiple sites in the ventricles. Causes the heart muscle to quiver, rather than contract, giving no effective CO.

Question 13

Ventricular fibrillation rate and rhythm

Answer 13

both irregular

Question 14

Ventricular fibrillation cause

Answer 14

MI, trauma, acid base imbalance, CAD, untreated vtach, R on T phenomena, drugs like epi, cocaine.

Question 15

Ventricular fibrillation effects

Answer 15

will lead to death if left untreated.

Question 16

Ventricular fibrillation treatment

Answer 16

follow ACLS guidelines–> CPR, defib, epinephrine or vasopressin and amiodarone or lidocaine.
