Non-invasive Diagnosis of Pulmonary Hypertension by Impedance Cardiography

"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."
