Question 1

When setting up a patient for exercise stress testing, which finding is an absolute contraindication to proceeding?

Accepted Answer

Unstable angina or recent MI within 2 days

Answer

Unstable angina and recent MI represent high-risk myocardial instability; exercising the heart in this state can precipitate fatal arrhythmias or rupture.

Question 2

B-type natriuretic peptide (BNP) is elevated primarily in patients with:

Accepted Answer

Heart failure with increased ventricular wall stress

Answer

BNP is released by ventricular myocytes in response to volume overload and increased wall tension, making it a sensitive marker of heart failure severity.

Question 3

On a 12-lead ECG, which leads provide a view of the inferior wall of the left ventricle?

Accepted Answer

II, III, and aVF

Answer

Leads II, III, and aVF are oriented toward the inferior surface of the heart and display changes associated with inferior wall ischemia or infarction.

Question 4

During a tilt-table test, syncope triggered by prolonged upright positioning with a drop in blood pressure and heart rate indicates:

Accepted Answer

Vasovagal (neurocardiogenic) syncope

Answer

The tilt-table test reproduces vasovagal syncope by provoking the cardioinhibitory and vasodepressor responses that cause sudden blood pressure and heart rate drops.

Question 5

Pulsus paradoxus, detected during blood pressure measurement, is a classic sign of:

Accepted Answer

Cardiac tamponade

Answer

Pulsus paradoxus is an exaggerated fall (>10 mmHg) in systolic blood pressure during inspiration, caused by pericardial fluid compressing the heart in tamponade.
