abstract = {Two different noninvasive ambulatory hemodynamic monitoring devices (belt-type and chest-type) based
on Electrocardiogram (ECG) and Impedance Cardiography (ICG) has been designed, fabricated and
tested. Hardware designs of the two ambulatory hemodynamic monitoring devices based on Tetrapolar
configuration and placement of the electrodes were introduced. Hemodynamic parameters such as Stroke
Volume (SV), Cardiac Output (CO) and Cardiac Index (CI) can be estimated according to Kubicek
Formula by extracting characteristic points and characteristic periods in the ICG Signal. CI is CO
divided by body surface area. CI is comparable among different people because it is not influenced
by the body height and weight. The body's physiological responses to postural change are primarily a
reaction to the change of gravity, because change of gravity can cause changes of blood flow distribution
in organs and tissues. Different body postures (upright or supine) can result in reducing or rising of
CO. The detection accuracy has also been validated with a commercial ICG detection instrument from
Mindray company, and the correlation coefficient is 0.83.},
