Outcome(s)

• Primary Outcome: For 30 volunteers, the lateral contraction ability and diastolic ability are first measured by transthoracic echocardiography in the horizontal position. The contractility is the ejection fraction (EF), fractionation fraction (% FS), and the mitral valve and tricuspid annulus systolic movement distance, which are said to be easy to measure and correlate well with EF. Measure (MAPSE, TAPSE) 2). For diastolic function, measure E / A and E / e'both left heart and right heart system 3). After that, keep the head low at 30 degrees for 7.5 minutes 4) and record the changes in contractile ability and diastolic ability. In addition, blood pressure and heart rate in the horizontal and low head positions are recorded as hemodynamics. The purpose of this study is how the general measurements EF,% FS, E / A correlate with the relatively new MAPSE, TAPSE, E / e'. And it is to examine how these values change depending on the low head.
