[New noninvasive methods of cardiovascular system function assessment].
Increasing development of noninvasive methods of the cardiovascular system assessment as a consequence of increasing experience and technological progress cause more increasing aviability and interest of this techniques from the side of clinicians and scientists. The aim of this study was to present two noninvasive techniques: photoplethysmography and impedance cardiography with explanations of the basis of action, possibilities and limitations. Employment of this two methods opening new perspectives in haemodynamic assessment in many clinical situations for instance: shock, pulmonary edema, heart insufficiency, arterial hypertension and eclampsia. These methods could optimize farmacotherapy or stimulation parameters in patients with heart stimulation as well as to come to know and understand correlations between autonomic nervous system activity and haemodynamic changes. Noninvasivity and low costs of these procedures cause that impedance cardiography and photoplethysmographic blood pressure measurement will become wide use and acceptable methods all over the world.
