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. In this study, 27 carotid bruits in 15 consecutive patients with carotid bruits and basal heart murmurs were analyzed by phonoangiography. Tape recordings we...

OBJECTIVE This study evaluated an existing SNOMED-CT model for structured recording of heart murmur findings and compared it to a concept-dependent attributes model using content from SNOMED-CT. METHODS The authors developed a model for recording heart murmur findings as an alternative to SNOMED-CT's use of Interprets and Has interpretation. A micro-nomenclature was then created to support ea...

SUMMARY A range-gated pulsed Doppler flowmeter has recently been developed that measures the average velocity of blood flow within a small tear-drop shaped (4 mm by 2 mm) sample volume. Unlike the continuous wave Doppler, the distance from the transducer face to the sampling site can be continuously varied by a range adjustment knob. Twenty patients with cardiac murmurs were evaluated in a noni...

The prevalence and clinical importance of false tendons were studied in 488 consecutive patients referred for echocardiography. Two hundred and eighty three (58%) patients had acquired heart disease, 91 (19%) had congenital heart disease, and 114 (23%) had normal hearts. Sixty six patients with normal hearts had innocent systolic murmurs and one had recurrent ventricular tachycardia. The overal...

Coronary heart disease is a leading cause of death around the world. Early and accurate detection this vital to reducing complications preventing failure attacks. This project creates an early-level diagnosis method that analyzes sound audio detect characterize anomalies including murmurs, arrhythmias, extra sounds. The dataset was obtained from Peter Bently’s Classifying Heart Sounds Database....

ISSN: 1652-6880, ISBN: 978-91-576-7323-7 Turbulence of various genesis in the left ventricular outflow tract (LVOT) causes systolic ejection murmurs. The prevalence of murmurs in adult boxer dogs is 50-80%, the majority of which are of low ...

Cardiac auscultation has been the central clinical tool for the diagnosis of valvular and other structural heart diseases for over a century. Physicians acquire competence in this technique through considerable training and experience. In Africa, however, we face a shortage of physicians and have the lowest health personnel-to-population ratio in the world. One of the proposed solutions for tac...

Diastolic murmurs have always been considered abnormal, but this report presents nine apparently normal children with high-frequency, early, diamond-shaped diastolic murmurs confirmed by intracavitary phonocardiography to arise within the left ventricle. Each child (aged 5 to 15 years) was referred for evaluation of a systolic murmur at the lower left sternal border, but an additional finding a...
