Photoplethysmography is a noninvasive method for fast diagnosis of blood flow disturbances in the venous system of the lower limbs. It is suitable for discriminating normal from pathological venous findings. The technique has been evaluated in three groups of subjects with edema of the lower extremities. The value of this screening method in the diagnosis of vascular disorders and edema of the lower limbs is discussed. Venous occlusion plethysmography is used for discriminatory and quantitative evaluation of venous function. The diagnostic value of strain gauge plethysmography was assessed in three groups of subjects. Measured parameters were venous capacity and venous outflow. Digital photoplethysmography is suitable for the discrimination of venous edema of the lower limbs from edema caused by other factors, and digital "strain gauge" plethysmography for the discrimination of edema of the lower limbs, caused by phlebothrombosis from edema caused by other factors.

D009202	Cardiomyopathies	A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).
