Study C3S : Comparison Among Healthy Subject

Left Ventricular 2D and 3D Strain in Healthy Subject : Comparative Study Between Two Echocardiograph (Vivid 9 General Electric et Epiq 7 Philips)

The aim of the C3S study is research an equivalence with longitudinal, radial and circumferential, global and segmental strain value, in left Ventricular in 2 and 3 dimension between two echograph General Electric Vivid 9 (GE Vingmed, Horton, Norway) et Philips Epiq 7.

Healthy volunteer will be inform about the study by email and press. They could join the clinical research team by email and phone to ask more questions about the study. Then the investigator, verify the eligibiliy of the volunteers and schedule an appointment for the visit of inclusion. During this visit, the patient's consent will be collected. One echocardiography will be complete on echograph General Electric Vivid 9 to collect the clinical data necessary for the study and to eliminate the presence of criteria of exclusions, the acquisition of the loops of ultrasound will be realized on both echographs by a first investigator. A second investigator will make the post-treatment of the ultrasound images on consoles ECHOPAC PC version 201, General Electric Medical System and Q Station version 3.5, Philips Healthcare in two different times, to obtain the values of the various strain.

Furthermore, an clinical exam, an ECG, a questionnary will be realized.
