Validation of Kinocardiography, New Technology for Cardiac Linear and Torsional Contractility Measurement, to Assess Heart Failure Patient With Low Ejection Fraction

Measuring cardiac contractility is commonly realized with gold standard echocardiography or MRI. Portable devices to measure this contractility are not available as for rhythm and electric function assessment. The new Kinocardiography technology could provide a non invasive and portable tool to measure contractility.

This device records the electric and mechanic function of the heart simultaneously. With electrodes and adequate electronics, ECG is recorded. 6 degrees of freedom accelerometers are also included in the device to measure the micro accelerations of the body at the body surface when the device is placed on the skin. Using physics principles and adequate calibration, those accelerations allow the investigators to calculate parameters such as kinetics energies related to cardiac contractility. Kinocardiography is a non invasive and portable technology.
