    • This study compares the systemic hemodynamics of normal subjects with those of patients having essential hypertension. Hemodynamic data is obtained by two methods: parameters that are measured directly from data obtained from the sensing and ECG electrodes and parameters that are calculated from echocardiography measured data. Hemodynamic functions were studied in 40 healthy, normotensive subjects (not hospitalized) and 40 hypertensive patients. Using these methods, we can determine stroke volume, cardiac output, thoracic fluid content, and measures of diastolic/sistolic function. Bioimpedance is reproducible method that can bring noninvasive hemodynamic data with greater accuracy. In summary, impedance cardiography is an exciting new application that appears to offer a useful, noninvasive method for hemodynamic assessment in critical patients in Emergency Department.
