a2-year-old cachectic cross-breed gelding was admitted toveterinary teaching hospital of university of tehran followingthe onset of a marked respiratory distress, coughing and ventraledema. clinical examinations indicated harsh respiratory andexpiratory sounds as well as jugular vein distention. therespiratory and heart rates were 35/min and 60 bpm, respectively.agrade iii/iv pansystolic murmur...

BACKGROUND Induction of pneumoperitoneum during laparoscopic surgery leads to diverse cardiovascular changes that can be used as a model to study pathophysiologic phenomena. Application of novel signal processing and figure extraction enabled searching for correlation between various signals and pathophysiologic setting. Our aim was to quantitatively correlate cardiac functionality (as expresse...

We hypothesized that vibrations created by the pulmonary circulation would create sound like the vocal cords during speech and that subjects with pulmonary artery hypertension (PAH) might have a unique sound signature. We recorded heart sounds at the cardiac apex and the second left intercostal space (2LICS), using a digital stethoscope, from 27 subjects (12 males) with a median age of 7 years ...

Clinical examination of any animal with respiratory difficulty should include auscultation of the thorax, Sometimes it is difficult to hear air movement in all or part of the lung fields. If lung sounds cannot be heard in one localized area of the chest, this suggests absence of air movement through one particular lung lobe, such as might occur with a consolidated lung lobe or neoplastic mass. ...

This paper describes a new method for the detection of sound from within the heart in man. It employs the technic and equipment of underwater listening developed and use(l by the Navy in antisubmarine warfare. Records are shown to illustrate the localization of heart sound production to an extent not possible by phonocardiograms from the chest wall. The technic has proved helpful in the evaluat...

To investigate the correlation of haemodynamic parameters with the intensity of the gallop sound (S3), use was made of right heart catheterization with a Swan-Ganz catheter to measure the pulmonary and right atrial pressures. The cardiac output was determined with the thermodilution method. A radiocardiogram was obtained after a bolus injection of technetium pertechnetate. The cardiopulmonary f...

OBJECTIVE To determine if heart murmur intensity grading performance can be improved using the heart sounds as an internal reference. METHODS Single-blind controlled trial of 100 medical students, residents, and pediatric attending physicians at a children's hospital. Groups of 1 to 3 participants were alternately assigned to intervention and control groups, reported their method of grading h...

contemporary art. I’d like an Andy Warhol, but the price is not yet quite right!” D Zelko Roncevic, chief of the paediatric cardiology department, Clinical Hospital, Mostar, says, “I always have a feeling that cardiac sounds and murmurs are a kind of music. The heart has a rhythm, and the normal heart sounds have the semblance of bass guitar and drum sounds. Some heart murmurs have a musical di...

One hundred normal subjects, mean age 51, who had had a simultaneous phonocardiogram and electrocardiogram at rest and after a double Master's test had a maximal treadmill stress test. Thirteen of 100 normal people (13%) had an abnormal maximal treadmill stress test with at least 1.0 mm of ischemic ST-segment depression. Ten of 29 normal subjects (34%) with a fourth heart sound and four of 11 n...
