dc.description.abstractIn thirty eight young healthy adult subjects, cardiac output was determined non-invasively by using two methods of electrode placement viz. vertical (uses silver braided wires in a band shape) and horizontal (conventional stick-on type surface ECG electrodes), using the technique of Impedance Cardiography. The recordings were taken in supine position on the same day in two separate sets with 30.0 min interval between two sets. In each set of recording, five successive recordings, each at an interval of five minutes were taken. The mean values of cardiac out put by two methods were compared. For the set I, the respective values (Mean +/- SD) of cardiac output by horizontal and vertical methods for the each of the five recordings were 4.87 +/- 0.77 and 5.03 +/- 0.64 for the first, 4.87 +/- 0.71 and 4.91 +/- 0.66 for the second, 4.99 +/- 0.67 and 5.00 +/- 0.70 for the third, 4.78 +/- 0.69 and 4.98 +/- 0.61 for the fourth, 4.84 +/- 0.69 and 4.98 +/- 0.62 for the fifth recording in supine position. The respective P values for these pairs for between the group comparisons were 0.33, 0.50, 0.96, 0.17, and 0.36. In addition, to see the repeatability for each method, within the group comparison was done, the P values were 0.71 and 0.91 for the horizontal and vertical methods, respectively. The mean value of cardiac output did not differ significantly between two methods for recordings of set II in supine position. The cardiac output measurement by placing four spot electrodes horizontally, gave consistent result on repeated measurements and their values showed concordance with the cardiac output values obtained by conventional four band electrodes tied around the chest.en_US
