Low Blood Pressure

Low Blood Pressure: Its Causes and Significance focuses on the important and interesting aspects of low arterial pressure. This book discusses the vasomotor control of arterial pressure; significance of low arterial pressure; autonomic-endocrine influences; and symptomatology of acquired hypopiesis. The parasympathetic or extended vagus system; arteriosclerosis of large vessels; psychical low arterial pressure; and agents causing vascular dilatation are also deliberated. This text likewise covers the exanthematous infections of doubtful etiology; atrophic cirrhosis of the liver; occasional difficulties in diagnosis; and control of low arterial pressure. This publication is intended for medical practitioners and clinicians aiming to acquire knowledge of low arterial pressure and its associations.
