Despite the widespread clinical appliciktion of cardiopulmonary resuscitation (CPR), the mechanism responsible for blood flow during this maneuver remains undefined, although it has been assumed that blood is squeezed from the heart by direct compression of the sternum. We studied the hemodynamics of CPR in 15 arrested dogs. During chest compression, pressures in the left ventricle, aorta, righ...

Hyperspectral image sensor developments on the study of the Earth's surface give way to images with higher spectral and spatial resolutions. In fact, the higher the resolution, the greater the size of these images. The use of these sensors by space-borne satellite systems will provide an enormous and continuous flow of data with constraints placed on onboard storage, and data transmission bandw...

objectives:hypertension is one of the most common diseases of the modern era. this study evaluates the effect of hydro-alcoholic celery leaf extract onsystolic blood pressure (sbp), heart rate (hr) and lipid profile in animals’ model of hypertension induced by fructose. materials and methods: sprague dawley rats were divided into five groups: 1) control group (free access to tap drinking water)...

This review article focuses on the morphological and functional alterations that characterize patients with myocardial bridges (MB) as well as the currently available diagnostic and treatment strategies. Because of incomplete understanding of the pathophysiology of MB, their clinical significance has been the subject of debate for the last quarter century. Investigational tools now available in...

A 36-year-old patient was referred because of fatigue and decreased exercise tolerance 20 years after separate aortic valve replacement and aortic root reconstruction. The presence of a loud systolic ejection murmur and persistent left ventricular hypertrophy led to the diagnosis of severe supravalvular aortic flow obstruction by indirect compression of a large pseudoaneurysm.

Background. A novel, micromobile foot compression device (MMC) has been developed to reduce the risk of venous thromboembolism associated with prolonged seated immobility. Objective. To compare the efficacy of the MMC with graduated compression stockings in augmenting lower limb venous blood flow. Patients/Methods. Twenty participants were randomised to wear the MMC or a graduated compression s...

INTRODUCTION Myocardial bridging with systolic compression (milking) of the left anterior descending coronary artery may be associated with myocardial ischemia. Little information is available about the long-term prognosis of patients with this coronary anomaly. MATERIAL AND METHODS A review was made of coronary angiographies of patients diagnosed as ischemic heart disease made between 1994 a...

myocardial bridging with systolic compression of the left anterior descending coronary artery (lad) may be associated with myocardial ischemia. in symptomatic myocardial bridging unresponsive to medical treatment, surgical unroofing of the left lad can be performed. little information is available about the long-term prognosis of patients with this coronary anomaly after the surgical unroofing,...

INTRODUCTION We proposed using compression sonography to observe the coaptation and collapse of the radial artery as a surrogate for automated cuff blood pressures (BP). We hypothesize that the pressure required to achieve coaptation and complete collapse of the artery would correlate to the diastolic and systolic BP, respectively. This pilot study was to assess the feasibility of ultrasound-gu...

This paper presents novel architectures for efficient implementation of Discrete Orthogonal Transforms (DOTs) using an FPGA based parameterisable system. These transforms are important in many signal and image processing applications including image and speech compression, filtering and coding. Two novel architectures for DOTs using both systolic architecture and distributed arithmetic design m...
