Quizplus · Accepted Answer

A thrill is a fine, palpable, rushing vibration, or a palpable murmur. Cardiac thrills generally indicate a disruption of the expected blood flow related to some defect in the closure of one of the semilunar valves (generally aortic or pulmonic stenosis), pulmonary hypertension, or atrial septal defect. A heave or lift is a more vigorous apical impulse. A thrust is a movement forward suddenly and forcibly. A murmur is an auscultated sound caused by turbulent blood flow.
