A simple objective screening method for diagnosis of the atrial septal defect (ASD) is needed. Acoustic signals were collected from 61 children with ASD and 60 with a physiological murmur. The second heart sound (S2) and the spectrum of systolic murm

To develop a digital algorithm that detects first and second heart sounds, defines the systole and diastole, and characterises the systolic murmur. Heart sounds were recorded in 300 children with a cardiac murmur, using an electronic stethoscope. A D

Foveal flicker sensitivity at 0.5–30 Hz was measured as a function of the spectral density of external, white, purely temporal noise for a sharp-edged 2.5 deg circular spot (mean luminance 3.4 log phot td). Sensitivity at any given temporal frequen

Background More than 90% of heart murmurs in children are innocent. Frequently the skills of the first examiner are not adequate to differentiate between innocent and pathological murmurs. Our goal was to evaluate the value of a simple and low-cost p

Spin lock (SL) MRI technique has been demonstrated to provide similar lesion/liver contrast to conventional MR technique. Multiple slice SL technique allows a large number of slices to be collected within a given repetition time due to the short echo

Although the phonocardiogram presents heart sounds and murmurs most precisely and it can offer clinically useful information, its usage as diagnostic tool is nowadays quite uncommon. One possible reason can be that auscultation findings are not recor

In this paper an improved algorithm for segmentation of phonocardiographic signal has been proposed. The algorithm is based on the use of spectrogram, which is calculated from the high-pass filtered phonocardiogram. The spectrogram is quantified to t
