The Phonocardiogram in Endomyocardial Fibrosis.
Endomyocardial fibrosis is a common cause of heart failure in Uganda. A clinico-pathological study of this cardiopathy reported by Ball et al. (1954) established that the fibrotic process, while involving the endocardium of the apices of the ventricles, not infrequently extends to the chorda, tendinee and the cusps of the atrioventricular valves, tethering them down and producing atrioventricul...
متن کاملThe phonocardiogram of aortic stenosis.
Aortic stenosis produces a systolic murmur of characteristic shape in the phonocardiogram both in the aortic and mitral areas. Sound records were taken in 20 patients with aortic stenosis. Thq phonocardiograph used for this investigation has been described elsewhere (Leatham, 1949), and consisted of crystal microphones, valve amplifiers, and both string and mirror galvanometers. Filters were u-...

متن کاملA Pictorial Presentation of Esophageal High Resolution Manometry Current Parameters
Introduction: High resolution manometry is the current technology used to the study of esophageal motility and is replacing conventional manometry in important centers for esophageal motility with parameters used on esophageal motility, following the Chicago Classification. This classification unifies high resolution manometry interpretation and classifies esophageal disorders. Objective: Thi...
متن کاملDeterministic Extraction of Building Parameters from High Resolution Sar Images
Urban structure detection, in terms of both geometric and electromagnetic features, from a single High Resolution (HR) SAR image is, nowadays, an interesting still open challenge. Within this framework a possible approach to extract information from a single HR SAR image is presented. We first define a set of geometric and radiometric parameters measurable on a SAR image of isolated buildings, ...
