Cardiology Practice Questions

Question 1

Which of the following signs of congestive cardiac failure constitute a major risk to the surgical patient undergoing anaesthesia ?

Accepted Answer

Jugular venous distention and third heart sound

Answer

Pedal oedema

Answer

Basal crepitations on auscultation

Answer

Cardiomegaly

Question 2

A 70-year-old man with heart failure presents with dyspnea. Pressure-volume loop analysis shows a rightward shift with decreased slope of the end-systolic pressure-volume relationship (ESPVR). His left ventricular end-diastolic pressure is 28 mmHg (normal 8-12 mmHg). Analyze which phase of the cardiac cycle is most directly affected by the elevated end-diastolic pressure.

Accepted Answer

Rapid filling phase shows reduced velocity and duration

Answer

Duration of isovolumetric contraction is prolonged

Answer

Mitral valve opens earlier in the cardiac cycle

Answer

Aortic valve closes later in the cardiac cycle

Answer

Atrial systole contributes a smaller percentage of ventricular filling

Question 3

A researcher is studying how electrical activity propagates across the heart. In order to do this, he decides to measure the rate at which an action potential moves within various groups of cardiac muscle tissue. In particular, he isolates fibers from areas of the heart with the following characteristics:

A) Dysfunction leads to fixed PR intervals prior to a dropped beat
B) Dysfunction leads to increasing PR intervals prior to a dropped beat
C) Dysfunction leads to tachycardia with a dramatically widened QRS complex
D) Dysfunction leads to tachycardia with a sawtooth pattern on electrocardiogram

Which of the following is the proper order of these tissues from fastest action potential propagation to slowest action potential propagation.

Accepted Answer

A > D > C > B

Answer

B > D > C > A

Answer

D > C > A > B

Answer

B > C > D > A

Answer

A > C > D > B

Question 4

What is the cardiac axis in the ECG provided?

Accepted Answer

Left axis deviation

Answer

Normal axis

Answer

Right axis deviation

Answer

Extreme axis deviation

Question 5

Concentric hypertrophy of left ventricle is seen in -

Accepted Answer

Congenital aortic stenosis due to bicuspid aortic valve

Answer

Mitral Stenosis

Answer

Aortic Regurgitation

Answer

Hypertrophic Obstructive Cardiomyopathy

Question 6

A patient complains of intermittent claudication, dizziness, and headache. What is the likely cardiac lesion?

Accepted Answer

Tetralogy of Fallot (TOF)

Answer

Atrial Septal Defect (ASD)

Answer

Patent Ductus Arteriosus (PDA)

Answer

Coarctation of the Aorta

Question 7

Dissection of which artery is seen in pregnancy?

Accepted Answer

Aorta

Answer

Carotid artery

Answer

Coronary artery

Answer

Femoral artery

Question 8

Which of the following is a risk factor for coronary artery disease (CAD)?

Accepted Answer

Increased homocysteine levels

Answer

High HDL

Answer

Low LDL

Answer

Decreased fibrinogen levels

Question 9

A 67-year-old man with an 18-year history of type 2 diabetes mellitus presents for a routine physical examination. His temperature is 36.9 C (98.5 F), his blood pressure is 158/98 mm Hg and his pulse is 82/minute and regular. On examination, the physician notes a non-tender, pulsatile, mass in the mid-abdomen. A plain abdominal x-ray film with the patient in the lateral position reveals spotty calcification of a markedly dilated abdominal aortic wall. Which of the following physiologic observations helps to account for the fact that 75% of the aneurysms of this patient's type are found in the abdomen and only 25% principally involve the thorax?

Accepted Answer

The average blood pressure in the abdominal aorta is higher than that in the thoracic aorta.

Answer

Diastolic pressure is greater in the abdominal aorta in the supine position.

Answer

Negative intrathoracic pressure reduces aortic wall tension in the thorax.

Answer

The average blood flow in the abdominal aorta is greater than that in the thoracic aorta.

Question 10

What is the most common cause of painful pericarditis?

Accepted Answer

Viral

Answer

Tuberculous

Answer

Uremic
