Exam 1 Wrong Qs

Question 1

True or False, the sympathetic nervous system barely affects ventricular foci?

Answer 1

True

Question 2

Supraventricular tachycardia is what? What are some examples? What would you see in an EKG?

Answer 2

Tachycardia originating above the ventricles (supra). Includes Afib and Aflutter. You’d see normal QRS cycles but P waves would vary

Question 3

What is vaso vagal syncope?

Answer 3

A response of the parasympathetic overstimulation in which the person passes out

Question 4

Wolf Parkinson White syndrome

Answer 4

Bundle of Kent allows electrical signal to bypass normal pathway, resulting in delta wave

Question 5

What ion propagates the AV node and SA node?

Answer 5

Calcium

Question 6

What ion propagates Atria, Ventricle, bundle of His and purkinje?

Answer 6

Na+

Question 7

Electrical signal pathway?

Answer 7

SA node > AV node > Bundle of His > left and right bundle branches > purkinje fibers

Question 8

Leads II, III, and AVF are the ___ leads

Answer 8

Inferior

Question 9

Leads I and AVL are the ___ leads

Answer 9

Lateral

Question 10

PAC vs PJC?

Answer 10

Early P wave embedded on the T wave (high amplitude). If amplitude is not high then we know the P wave is not embedded in which case it is missing, making it a PJC

Question 12

Torsades vs V fib?

Answer 12

Torsades will have high amplitude and up and down amplitude

V fib will have normal or low amplitude but no identifiable QRS

Question 13

A flutter is known as ________ pattern

Answer 13

Sawtooth

Question 14

Ventricular tachycardia vs supra v tachycardia?

Answer 14

Vtach is a fast beat originating from the ventricles so abnormal QRS, whereas supra v tach originates above the ventricles so normal QRS but P prime
