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.
The purpose of this research is to better understand the use of heart ultrasounds to estimate heart function.
