What's the difference between auscultation and bruit?

Auscultation


Definition:

  • (n.) The act of listening or hearkening to.
  • (n.) An examination by listening either directly with the ear (immediate auscultation) applied to parts of the body, as the abdomen; or with the stethoscope (mediate auscultation), in order to distinguish sounds recognized as a sign of health or of disease.

Example Sentences:

  • (1) To evaluate the relationship between the motion pattern and degree of organic change of the anterior mitral leaflet (AML) and the features of the mitral component of the first heart sound (M1) or the opening snap (OS), 37 patients with mitral stenosis (MS) were studied by auscultation, phonocardiography and echocardiography.
  • (2) Indirect blood pressure measurement techniques included automated oscillometry, manual auscultation, visual onset of oscillation (flicker) and return-to-flow methods.
  • (3) Rapid heart beat was found accidentally by auscultation.
  • (4) In contrast to other methods (ECG, inspection, auscultation, blood gas analysis), it immediately detects an impending lack of oxygen, whatever its cause.
  • (5) Although the continuous murmur is an unusual sign in patients with pulmonary embolism, its auscultation is often quite distinctive, and its appearance may lead to more definitive diagnostic studies when the presentation or associated clinical findings are nonspecific.
  • (6) An apparently primitive cervical bruit corresponded to a lesion of the carotid bifurcation in 61% of the cases (positive predictive value) whereas a normal bifurcation was detected in 70% of the cases in which the cervical bruit was considered as secondary (negative predictive value); the diagnostic accuracy of the "critical auscultation" has a value therefore of 63%, with a sensitivity of 84% and a specificity of 40%.
  • (7) In 43% of the patients with pulmonary tuberculosis no abnormal signs were registered by auscultation.
  • (8) A technique of thoracotomy via the triangle of auscultation is described.
  • (9) Echocardiography supports the diagnosis of MVP made by auscultation in over 90% of individuals, with excellent reproducibility.
  • (10) Cases of neonatal seizures and persistent abnormal neurological signs followed by survival were twice as frequent in the intermittent auscultation group, and this differential effect was related to duration of labor.

  • (12) Testing consisted of spirometry, lung auscultation, and measurement of vital signs.
  • (13) Two of the four seronegative children developed a mild illness characterized by rhinorrhea and wheezing on auscultation; none had fever.
  • (14) During exercise, mean arterial pressure (MAP, brachial auscultation) was significantly lower (P less than 0.03) and heart rate significantly higher (P less than 0.02) during the prazosin trials; plasma catecholamine concentrations were unaffected.
  • (15) Diagnosis is made by following the classical physical diagnostic procedures of inspection, palpation, and auscultation.
  • (16) The ability of the auscultated acceleration test to predict nonstress test results after selected variables were controlled for was as follows: sensitivity, 75%; specificity, 97.6%; false-positive results, 14.3%; and false-negative results, 4.7%.
  • (17) As regards auscultation, a plea is made for differentiation between obstructed and non-obstructed consolidation of lobes, a point recognized by some clinicians, but not enunciated with clarity by teachers.
  • (18) The forceps delivery rate was 8.2% in the electronic fetal heart monitoring group compared with 6.3% in the intermittent auscultation group, and this excess was explained by more instrumental deliveries prompted by fetal heart rate abnormalities.
  • (19) Intraobserver and interobserver agreement in classifying all specific TMJ sounds at palpation and auscultation was acceptable to moderate (kappa value = 0.49 to 0.74).
  • (20) Twenty-seven of these 30 joints were treated with the appliance until the joints were silent to auscultation.

Bruit


Definition:

  • (n.) Report; rumor; fame.
  • (n.) An abnormal sound of several kinds, heard on auscultation.
  • (v. t.) To report; to noise abroad.

Example Sentences:

  • (1) The disappearance of the bruit was associated with poor renal function.
  • (2) Two hundred and forty-one residents were examined for carotid bruits and signs of previous stroke.
  • (3) Cerebral angiography was performed in 18 of the patients with carotid bruits.
  • (4) Major intra-abdominal arteriovenous fistulas usually present with a machinery bruit over a pulsatile mass, but may present more subtly with pain and otherwise unexplained hematuria.
  • (5) An apparently primitive cervical bruit corresponded to a lesion of the carotid bifurcation in 61% of the cases (positive predictive value) whereas a normal bifurcation was detected in 70% of the cases in which the cervical bruit was considered as secondary (negative predictive value); the diagnostic accuracy of the "critical auscultation" has a value therefore of 63%, with a sensitivity of 84% and a specificity of 40%.
  • (6) In frank strokes it was 3.7%; in transient ischemia, 0.77%; and zero for chronic ischemia and asymptomatic bruits.
  • (7) Patients with HS bruits had a stroke incidence of 24 per cent and a transient ischemic attack (TIA) incidence of 16 per cent, which were significantly higher (P greater than 0.01) compared to the patients with NHS bruits (4.8% incidence of stroke and 3.2% incidence of TIA).
  • (8) Vascular disease, epigastric bruit, and impaired renal function were commoner in the renal artery stenosis patients than in the 81 with normal arteriograms, but there were no features pathognomonic of stenosis.
  • (9) Patients with non-focal neurological symptoms and carotid bruit were more likely to have a significant stenosis than asymptomatic patients with carotid bruit (P = 0.0069 Fisher's Exact Test).
  • (10) On cardiac examination, a pansystolic bruit and a diastolic rumble were audible at the tricuspid focus.
  • (11) PAG vascular bruits were characteristic hemodynamic disorders.
  • (12) The TIAs developed in four patients with HS bruits and in two patients with NHS bruits.
  • (13) All three patients suffered from pain in the abdomen and back, a palpable pulsatile abdominal mass and an audible continuous harsh bruit.
  • (14) The prevalence of asymptomatic carotid bruit is 4 per cent in the general population aged over 40 years.
  • (15) No association was found for diastolic blood pressure, myocardial infarction, angina, diabetes, or carotid bruits.
  • (16) Phonoangiography, quantitative analysis of arterial bruits, has been shown to provide accurate noninvasive diagnosis of uncomplicated carotid arterial stenosis, but had not been tested where cervical bruits from other sources were present.
  • (17) A periorbital bruit and venous engorgement of the palpebral and bulbar conjunctivae are pathognomonic features.
  • (18) Bruits were recorded at the skin surface, analyzed by a minicomputer, and the degree of arterial stenosis estimated using a recently derived theory of sound production by turbulent blood flow.
  • (19) Phonoangiography, as a noninvasive quantitative analysis of arterial bruits, was conducted just prior to standard invasive radiographic angiography in 135 patients.
  • (20) Presenting symptoms were claudication (n = 8), rest pain or nonhealing ulcers (n = 7), transient ischemic attacks (n = 6), asymptomatic bruit (n = 1), and renal insufficiency (n = 1).
