This is a single-group, observational study which will involve obtaining two echo scans of recruited patients. All recruited patients will undergo echo scans by both novice users (nurses) and experts (echo sonographers). Image quality between novices and experts as well as the ability to calculate LVEF from novice and expert scans and the quality of the LVEF calculated via KOSMOS-EF compared to LVEF calculations by expert cardiologists will occur in post-hoc Echo image analysis

| Assessment of Automatic Structure Labelling | A panel of cardiologists will access and determine via a majority vote if the frame-level false discovery rate (FDR) of automated cardiac structure labeling as determined by expert cardiologists for scans acquired by cardiac sonographers. | Up to 2 months from the completion of the study or when all expert cardiologists readers independently complete their assessments |

All patients admitted to the Emergency Department Observation Unit (EDOU) will be eligible for enrollment. Patients admitted to the EDOU often spend a prolonged amount of time in the EDOU (often > 24 hours) awaiting further testing, therapies, or specialist consultations, thus recruiting from this pool of patients is most likely to allow for completion of study procedures without impacting the course of their clinical care

| Manual vs. KOSMOS-EF for Sonographer Scans | Measurements are computed for A4C and A2C scans acquired by sonographers . We will compare KOSMOS-EF LVEF calculation to LVEF calculated by a panel of cardiologists via a majority vote. | Up to 2 months from the completion of the study or when all expert cardiologists readers independently complete their assessments |
| Assessment of Left Atrial Size | A panel of cardiologists will access and determine via a majority vote if a study exam acquired by a nurse is of sufficient image quality to make a qualitative visual assessment of Left Atrial Size. | Up to 2 months from the completion of the study or when all expert cardiologists readers independently complete their assessments |
