Question

Quizplus · Accepted Answer

A loud P2 (second heart sound) is typically indicative of pulmonary hypertension, which causes increased pressure in the pulmonary artery leading to the right ventricle having to work harder to pump blood through the lungs. This results in a more forceful closure of the pulmonary valve, leading to a louder second heart sound. Mitral regurgitation, gallop rhythm, and tricuspid atresia would not necessarily be associated with a loud P2.
