selecting 46 PSLA view video clips from patients with normal systolic function.Echocardiograms were performed by ultrasound technicians, interpreted by cardiologists, de-identified, and exported from the cardiology database.Collected data included a B-mode clip of the PSLA, the recorded lateral e', and EF.Emergency physicians trained in our simplified diastolic assessment method were the subjects of the study.They reviewed the B-mode clips and determined whether diastolic dysfunction was present, comparing their interpretations with formal cardiology assessments, specifically the lateral e'.Results: Three emergency physicians with FPD in AEUMS reviewed 46 echocardiograms, totaling 138 data points.Of the 46, 25 showed diastolic dysfunction (lateral e' < 10 cm/s), and 21 did not.Sensitivity and specificity were 82.9% and 90.3%, respectively.The average lateral e' for accurately identified cases of diastolic dysfunction was 7.1 cm/s, while for non-dysfunction cases, it was 12.5 cm/s.Conclusions: Our study suggests that a novel eyeball approach to assessing diastolic dysfunction shows significant promise.Emergency physicians successfully evaluated diastolic function, supported by comparing lateral e' averages in correctly identified cases.This simplified method may become a valuable tool in clinical settings, particularly where rapid decision-making is critical.Such innovations could lead to more intuitive and efficient bedside assessments of heart failure patients in the future.
