impedance cardiography

Abbreviation: ICG
A noninvasive means of determining cardiac output in which the stroke volume of each cardiac contraction is determined by measuring beat-to-beat changes in the electrical impedance of the chest and neck.
Synonym: electrical impedance plethysmography

According to the data quoted above, it appears that PEP is a useful parameter in assessing the impact of occupational work in its wide sense on the cardiovascular system, and impedance cardiography seems to be a convenient tool for its determination.
Specificity and sensitivity of impedance cardiography for detection of pulmonary artery hypertension have been calculated.
Impedance cardiography is sensitive and specific method in diagnostics of pulmonary artery hypertension: the pulmonary artery hypertension was diagnosed by computed mean blood pressure in pulmonary with sensitivity of 72 %, specificity--90 %, and by systolic blood pressure in pulmonary artery--with sensitivity of 96 %, specificity 90%.
