impedance plethysmography

Impedance plethysmography is a non-invasive method used to detect venous thrombosis in these areas of the body.

Impedance cardiography (ICG), also referred to as electrical impedance plethysmography (EIP), has been researched since the 1940s.

Diagnoses were commonly performed by impedance plethysmography in the 1970s and 1980s, but the use of Doppler ultrasound techniques, with their increased sensitivity and specificity, largely superseded this method.

Impedance phlebography, or impedance plethysmography (IPG), is a non-invasive medical test that measures small changes in electrical resistance of the chest, calf or other regions of the body.
