What's the difference between bruit and murmur?

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).

Murmur


Definition:

  • (v. i.) A low, confused, and indistinct sound, like that of running water.
  • (v. i.) A complaint half suppressed, or uttered in a low, muttering voice.
  • (v. i.) To make a low continued noise, like the hum of bees, a stream of water, distant waves, or the wind in a forest.
  • (v. i.) To utter complaints in a low, half-articulated voice; to feel or express dissatisfaction or discontent; to grumble; -- often with at or against.
  • (v. t.) To utter or give forth in low or indistinct words or sounds; as, to murmur tales.

Example Sentences:

  • (1) The sounds were loudest along the left sternal border, exhibited an increase in intensity during inspiration and were associated with right atrial gallop sounds and with murmurs of tricuspid regurgitation.
  • (2) Based on initial auscultatory findings, patients were divided into: (1) single or multiple apical systolic clicks with no murmur (n = 99); (2) single or multiple apical systolic clicks and a late systolic murmur (n = 129); and (3) single or multiple apical clicks and an apical pansystolic murmur or murmur beginning in the first half of systole (n = 63).
  • (3) In the reported case the murmur grew in the beginning and then disappeared spontaneously.
  • (4) The following factors of these patients were analyzed: age, sex, civil status, socio-economic level, occupation, family antecedents, personal antecedents, smoking, alcoholism, presence of cardiac murmurs, arrhythmias, and electrocardiogram.
  • (5) The clinical history of recurrent bronchitis and dyspnoea during exercise, the presence of right parasternal murmur with normal heart size and normal blood gases justified the execution of an arteriovenous thoracic angiography which revealed the presence of a cirsoid aneurysm supplied by the internal and external mammary arteries.
  • (6) We report a case of a 17 year old boy who was referred for evaluation of a large anterior mediastinal mass, causing dyspnea and cough and resulting in a harsh systolic murmur.
  • (7) 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.
  • (8) The patient was asymptomatic and a heart murmur and abnormal electrocardiogram were discovered incidentally.
  • (9) Thus, the murmur of MR derives its prognostic significance from integration of multiple clinical, radiographic and electrocardiographic characteristics.
  • (10) Patent ductus arteriosus murmurs developed in shielded patients at a later date, they required less vigorous treatment (ie, indomethacin), and they had shorter hospitalizations (74 v 85 days; P less than .05).
  • (11) Healthy women students who asked for oral contraceptives were carefully examined to ascertain whether they had a cardiac murmur.
  • (12) The clinical picture was relatively nonspecific, and 32% of the patients had no heart murmurs initially.
  • (13) Of the total 47 episodes, carditis was manifested by a significant murmur without previous RF or any known rheumatic heart disease in 40%; change in the character of a murmur under observation or the appearance of a new murmur in 15%; and acute pericarditis in 19%.
  • (14) Acoustic information about the place of articulation of a prevocalic nasal consonant is distributed over two distinct signal portions, the nasal murmur and the onset of the following vowel.
  • (15) A 59-year-old woman hospitalised because of dyspnea and a heart murmur in a context of pyrexia was found to have evidence of obstruction of the pulmonary arterial system, clearly defined by ultrasonography, catheterisation and angiography and Imatron scan.
  • (16) All murmurs contained dominant frequencies that varied with time.
  • (17) Immediately after the implantation of a temporary transvenous right ventricular pacemaker, a high-pitched systolic musical murmur was heard at the lower left sternal border.
