초록
In this paper, cardiac parameters and relationship between stroke volume and impedance change were explained, and an impedance cardiograph was designed and constructed, and its accuracy was verified by experiment. Useful cardiac parameters such as stroke volume and contractility of cardiac muscle were measured noninvasively. The reproducibility of the instrument was measured to be better(less than 10%) than that of clinical standard method such as thermodilution. Hence impedance cardiography was found to be better technique for monitoring stroke volume and contractility of patients for pre and post operation, and pharmacological studies.
