Haemodynamic Abnormalities Recorded With Cardiac Catheterization Along With Body's Surface Micro-accelerometers (KT-KCG)

Patients suffering from severe heart failure regardless of the etiology will undergo a cardiac catheterization as required by their medical condition. The SCG and BCG signals will be recorded simultaneously to the catheterization by the mean of an unintrusive and friendly device consisting of two houses, the first one placed on sternum and the second one in the lumbar column. The device will record a continuous tracing synchronized with the intracavitary pressure profiles recorded during the invasive procedure.
