Non-invasive Diagnosis of Pulmonary Hypertension by Thoracic Impedance Cardiography - a Prospective Study

The goal of the study is to prospectively evaluate Impedance Cardiography as a tool to detect pulmonary hypertension. According to our hypothesis Impedance Cardiography is a valuable method to differentiate patients without pulmonary hypertension from patients with pulmonary hypertension. The main objective is to determine the sensitivity and specificity in comparison to the gold standard right heart catheterization.
