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.

| Impedance Cardiography | Diagnostic Test | Impedance Cardiography will be conducted in patients with suspected Pulmonary Hypertension within an interval of 24 hours to right-heart catheterization. Usually, 8 electrodes will be attached on the neck and thorax of the patient. These electrodes will produce current (max 400µA) and measure the voltage which is produced by the current running through the body. The Signal will be analyzed for specific signs of Pulmonary Hypertension. At the same time electrocardiography and non-invasive continuous blood pressure will be measured. |
| Measure | Description | Time Frame |
|---|---|---|
| Diagnosis of pulmonary hypertension | The sensitivity and specificity of Impedance Cardiography in the diagnosis of pulmonary Hypertension (as compared with the Gold Standard right heart catheterization) will be determined. | 1 hour |
