In 20 newborn thoroughbred foals cardiovascular examinations were made on the heart rate and detailed auscultation of the cardiovascular murmurs, which were also recorded by phonocardiography, was conducted between birth and two weeks of age. A transient bradycardia, which was slower than the near-term fetal heart rate, was noted in neonates immediately after birth. Rapid and progressive increa...

Purpose: We aimed to reveal the difference in the rate of congenital heart disease (CHD) presence between the neonates with and without cardiac murmurs in neonates with congenital gastrointestinal malformations (CGM). Patients and methods: We report on 115 infants treated between 1995-2000 with CGM. In group A, echocardiographies were performed only to those with murmurs. Group B, all patients ...

acute rheumatism are not commonly met with in this country, I have thought them worthy of record. For the abstract of the notes of these cases, I am indebted to Mr. Reilly, Assistant Apothecary of the Ward. In both cases the endocardial lining membrane was affected, and valvular murmurs developed ; in the case of AY. M. a systolic bruit was audible loudest over the aortic valves, not at the ape...

In a prospective study murmurs increased in intensity with carotid sinus pressure in 18 of 26 patients with hypertrophic obstructive cardiomyopathy (HOCM) (sensitivity, 69.2 percent for the 26 patients, 85.7 percent for the 21 patients in whom heart rate and blood pressure decreased with carotid sinus pressure). On the other hand, the murmur remained constant or decreased in all but one of 104 ...

The general practitioner has to deal almost daily in his work with the problem of systolic murmurs. He finds such murmurs often in apparently healthy children during a routine check and is then confronted by the question whether to consider these murmurs as of no importance, or to investigate further. There exists a wide discrepancy among publications on the incidence of systolic murmurs in chi...

The clinical differentiation of the apical systolic murmurs arising at the mitral and aortic valves may be difficult. This is especially so when the murmur of aortic origin is audible only at the apex or is loudest at this site. Phonocardiography gives further help in that the murmur of aortic stenosis is diamond shaped and ends before the aortic second sound while that of mitral regurgitation ...

Heart sounds and murmurs are timevarying signals that would best be analyzed using timefrequency analysis. Windowed Wigner-Ville distribution (WWVD) and smooth windowed Wigner-Vffle distribution (SWWVD) are used to obtain the timefrequency representation of the signal. Determination of parameter setting of WWVD and SWWVD will eliminate the cross-terms and improve time frequency representation. ...
