thrill
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.
systolic thrill one felt over the precordium during systole in aortic stenosis, pulmonary stenosis, and ventricular septal defect.
thrill (thr l)n. The vibration accompanying a cardiac or vascular murmur, detectible on palpation. |
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.
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.
diastolic thrill
one felt over the precordium during diastole in advanced aortic insufficiency.
presystolic thrill
one felt just before the systole over the apex of the heart.
systolic thrill
one felt over the precordium during systole in aortic stenosis, pulmonary stenosis and ventricular septal defect.
thyroid thrill
palpable over a colloid goiter with a large blood supply.
thrill
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
