diastolic thrill  one felt over the precordium during ventricular diastole in advanced aortic insufficiency.

hydatid thrill  one sometimes felt on percussing over a hydatid cyst.

presystolic thrill  one felt just before the systole over the apex of the heart.

thrill

Etymology: AS, thyrlian, to pierce

a fine vibration, felt by an examiner's hand on a patient's body over the site of an aneurysm or on the precordium, resulting from turmoil in the flow of blood and indicating the presence of an organic murmur of grade 4 or greater intensity. A thrill can also be felt over the carotids if a bruit is present and over an arteriovenous fistula in the patient undergoing hemodialysis. Compare bruit, murmur.

thrill,

n 1. a vibration felt on the chest wall over the heart. It is caused by the eddy flow of the blood, which is produced by a structural defect in the heart.
2. palpable high-frequency vibration that may accompany cardiac murmurs or vascular disease.

thrill

a vibration caused by the movement of fluid felt by the examiner on palpation. Created by turbulence in a fluid column passing through an incompetent valve, or from a vessel of smaller caliber to a larger. The larger the orifice the bigger the thrill. Also by sharp firm percussion on one part of the abdomen and feeling a shock wave over a distant part of the abdomen—the so-called fluid wave.

Cardiology A palpable murmur that correlates with zones of maximum intensity of auscultated sounds; rough lower sternal border thrills occur in ventricular septal defect, apical systolic thrills are associated with mitral valve insufficiency; diastolic thrills may be palpated in AV valve stenosis Vox populi Whee, whoopie, yippie, yeeeehaaa, etc
