Correct Answer is A
Explanation
A. The view of the electrical current changes in relation to the lead placement – Each ECG lead offers a different angle or view of the heart's electrical activity, so the waveforms in leads I, II, and III naturally look different. This variation helps clinicians assess different parts of the heart.
B. Conduction of the heart differs with lead placement – The heart's electrical conduction system functions independently of lead placement; only the view of the conduction changes.
C. Electrocardiogram (ECG) equipment has malfunctioned – Lead differences are expected and normal; this is not a sign of malfunction.
D. The circadian rhythm has changed – Circadian rhythms affect general physiological patterns but do not cause variation in ECG lead appearance.
Correct Answer is B
Explanation
A. Blood flowing back from the left atrium to the left ventricle describes mitral regurgitation, not aortic regurgitation.
B. Aortic regurgitation involves the backflow of blood from the aorta into the left ventricle during diastole due to an incompetent aortic valve. This leads to volume overload in the left ventricle.
C. Obstruction of blood from the left atrium to the left ventricle occurs in mitral stenosis, not aortic regurgitation.
D. Obstruction of blood flow from the left ventricle is characteristic of aortic stenosis, not aortic regurgitation.
