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

NCT03821766 · Status: WITHDRAWN · Type: OBSERVATIONAL

Summary

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.

Conditions

Interventions

DEVICE

Ballistocardiography and seismocardiography

SCG and BCG signals will be recorded by the mean of an unobtrusive and friendly device consisting of two houses, the first one placed on the sternum and the second one place on the lumbar region near the subject's center of mass. The signal will be transferred to a tablet by Bluetooth and tracings will be analysed automatically with Matlab. The SCG+BCG signals are synchronized to the intracardiac pressure tracings in order to allow a comparative interpretation between the two tracings.
