A distinct and previously undescribed syndrome has been observed in six Saudi Arabian patients from two highly inbred families. The parents were normal, indicating an autosomal recessive pattern of inheritance. All the patients have a distinctive facial appearance, hypogonadism, sparse or absent hair, diabetes mellitus, mental retardation, mild deafness, and variable S-T and T wave abnormalitie...

Respiration and body position changes (BPC) affect on the morphology of electrocardiograph (ECG). This variation can be modeled by the rotation of vectorcardiographic (VCG) loop. To visualize the distortion on ECG, caused by these motion artifacts, a software simulation environment was created. With user adjustable rotation angles it enables observation of the influence of VCG loop movement on ...

This article reviews the ST segment and T wave abnormalities seen in non-acute coronary syndrome (ACS) electrocardiograph presentations. Particular emphasis is placed on the distinction of these non-ACS syndromes from acute coronary syndrome related ST segment and or T wave change.

On examination, the epigastrium was tender but no mass was palpable. Investigations for his epigastric pain showed normal levels of serum amylase, normal electrocardiograph, normal erect abdominal and chest Xray. Further tests done included abdominal ultrasound that showed hyperechoic lesion in the gallbladder, suggestive of a polyp. The liver, spleen and pancreas were reported as normal. OGDS ...

Parametric modeling of non-stationary signals is addressed in this article. We present several models based on the characteristic features of the modelled signal, together with the methods for accurate estimation of model parameters. Non-stationary signals, viz. transient system response, speech phonemes, and electrocardiograph signal are fitted by these feature-based models.
