Abstract Electrical impedance can be measured in the leg by a simple noninvasive technic, somewhat analogous to electrocardiography. Normal tracings show a marked fall in impedance with deep inspiration, due to increased local venous blood volume. In the presence of deep venous thrombosis, these respiratory changes are damped or obliterated. Based on use in fifty-one patients, measurement of electrical impedance has proved to be a safe and useful screening procedure for the diagnosis of deep… CONTINUE READING
