A thrill is a fine, palpable, rushing vibration—a palpable murmur. Cardiac thrills generally indi-cate 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 lift is another term for a heave, which is a more vigorous apical impulse. A thrust is sudden, forcible forward movement.
