About

The ballistocardiography (BCG) and the seismocardiography (SCG) are old techniques recording the vibrations at the skin level generated by the acceleration and displacement of the blood and cardiac mass at each cardiac contraction. The former records the acceleration near the subject's center of mass, the latter at the local chest wall. So far, the unclear physiological origin of those acceleration signals has led to important ambiguities in their scientific and clinical interpretation. Therefore, several ongoing studies would aim to highlight the physiological genesis of those acceleration-induced signals.

Indeed, the main objective of this study is to correlate the BCG and SCG signals recorded at the body surface with several haemodynamic parameters recorded invasively during a cardiac catheterisation, pulmonary pressure, wedge pressure, cardiac output to cite a few.

Full description

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.

Heart failure

Description:

Patients suffering from heart failure regardless to the etiology will undergo cardiac catheterization according to their medical condition. the SCG and BCG signals will be recorded along with the intracavitary pressure profiles detected invasively with the cardiac catheterization.
