Question

A 19-year-old woman comes to the emergency department because, she says, "I'm burning up." Medical history is significant for intravenous drug use. Physical examination discloses a systolic heart murmur over the precordium. An expected physical finding will be which of the following? a. Decreased intensity of S1 b. Increased intensity of the murmur with deep inspiration c. Increased intensity of the murmur with forced expiration d. Positive Kussmaul sign (rise in jugular venous pulse with inspiration) (E) Right-sided gallop

Answer 1

Answer:

The correct option is B: Increased intensity of the murmur with deep inspiration

Explanation:

Most times, systolic heart murmurs do not mean that the individual might be suffering from a cardiac disease, it is simply connected to physiologic increases in the velocity of blood flow. A history of genetic diseases, intravenous drug abuse, and rheumatic fever, to mention but a few, are closely associated with heart murmurs. With deep inspiration, such murmurs, especially that of insufficiency of the tricuspid, increases in intensity.
