研究概览
简要总结
The purpose of this research is to better understand the use of heart ultrasounds to estimate heart function.
详细描述
This research involves ultrasounds of the heart by two different emergency medicine doctors who are residents in training. Results from the two doctors will be compared to see how similar they are. This research will help us understand if heart ultrasounds can be used to see how well the heart pumps blood and if similar results are obtained from different doctors.
The doctors will use ultrasound of the heart to measure E-Point Septal Separation (EPSS). EPSS is the distance between two parts of the heart, the mitral valve and the ventricular septum. EPSS is measured in millimeters (mm). EPSS can estimate left ventricular ejection fraction (LVEF) as a measure of how well the heart pumps blood.

结局指标
主要结局
Mean change in millimeters between E-Point Septal Separation (EPSS) measurements of the heart by two physicians
时间窗: During procedure
Two physicians will use the same ultrasound device to measure the E-Point Septal Separation (EPSS) on the same patients. EPSS is the distance between two parts of the heart, the mitral valve and the ventricular septum. The mean change in EPSS measurements in millimeter will be calculated.
次要结局
- Percent change in Left Ventricular Ejection Fraction (LVEF) estimated from ultrasound compared to a formal transthoracic echocardiogram.(During procedure)
