Question 1

Sinus Arrhythmia

Answer 1

Increase with inhalation, decrease with exhalation

Question 2

1st Degree AV Block

Answer 2

Prolonged P to Q interval

Question 3

2nd Degree AV Block

Answer 3

SA to AV impulse blocked from conducting the ventricles

Question 4

3rd Degree AV Block

Answer 4

complete dissociation between AV node and ventricles, no relationship between P ad QRS complex

Question 5

Sick Sinus Syndrome

Answer 5

Idiopathic dysfunction of SA node, random discharge or not at all
Not responsive to anticholinergics

Question 6

Ventricular Premature Complex

Answer 6

Ventricles depolarising with out SA node influence
Positive = right ventricle
negative = left ventricle

Question 7

Ventricular Escape Complex

Answer 7

when ventricles have not contracted for a prolonged period, they will conduct themselves
normally occur with bradyarrhythmia
no Lidocaine

Question 8

Ventricular Tachycardia

Answer 8

four or more VPCs in succession with an increased HR
decreased filling time

Question 9

Answer 9

low Hr with four or more VPCs in succession
caused by: anaemia or opioids

Question 10

Answer 10

terminal arrest rhythm
