AV block that causes fainting due to the initially suppressed state of the Purkinje fibers

Answer 15

Stokes-Adams syndrome

Question 16

Cushing reflex

Answer 16

Hypertension, irregular respirationand bradycardia due to activation of the CNS ischemic response and baroreceptor reflex in patients with increased intracranial pressure.

Question 20

Define. Chronotropic incompetence.

Answer 20

Failure to appropriately increase heart rate during exercise.
Unable to achieve 85% of predicted maximal heart rate at peak exercise.

Question 21

Chest discomfort associated with physical exertion or stress, Relieved within 5~10 min by rest and/or sublingual nitroglycerin

Answer 21

Stable angina pectoris

Question 22

What is unstable angina?

Answer 22

Angina pectoris with at least one of three features:
1. Occurs with minimal exertion or at rest, usually lasting >10 min

2. Severe and of new onset (within the prior 4-6 weeks)
3. Has a crescendo pattern (i.e., distinctly more severe, prolonged, or frequent than previous)

Question 23

How do you elicit abdominojugular reflux?

Answer 23

Apply pressure on the right upper quadrant for 10 seconds. Positive response: rise of > 3cm in JVP for at least 15 seconds after release of pressure.
