Ambulatory impedance cardiography gives useful values of stroke volume
December 30th, 2004
A recent report on stroke volume and systolic time intervals described a beat-to-beat comparison between echocardiography and ambulatory impedance cardiography in supine and tilted positions. Investigators in Poland report, "The aim of the study was to compare stroke volume (SW, ejection time (ET) and pre-ejection period (PEP) measurements obtained using a central haemodynamics ambulatory monitoring device based on impedance cardiography (ICG), in supine and tilted positions (60degrees), with pulsed Doppler echocardiography as a noninvasive reference method." G. Cybulski and colleagues of the Medical Research Center in Warsaw explained, "The...
