When can I expect to receive the results? If a doctor is present during the test or reviews it while you are still in the office, you may be able to get the results before you leave. However, the doctor is not
For example, patients with HCM may have a family history of sudden cardiac death in 1st-degree relatives at a young age. Second, the initial evaluation of patients with clinical signs of or symptoms of heart disease. This includes palpitations, syncope, pre-syncope, newly diagnosed bundle ...
Results EchoCLIP is an echocardiography vision–language model trained with 1,032,975 video–text pairs derived from 224,685 echocardiography studies across 99,870 patients across a decade of clinical care (Table 1). In a self-supervised approach, EchoCLIP is trained on pairs of echocardiogram im...
Moreover, due to its high interpretability, the results provide valuable medical insights regarding the identification of urgent patients for tests through the extraction of decision rules from the OSDT model. Conclusions The method demonstrated state-of-the-art predictive performance, affirming its ...
starting from the first frame of the video. The final prediction was performed by averaging all the predictions from individual frames. Several alternative methods were explored in order to aggregate frame-level predictions into one patient-level prediction and did not yield better results compared to...
example, there may have been higher concordance if the anesthesiologists evaluated TEE results after operation. Another limitation to our study is that most of our quantitative data were published nearly 20 years ago. If these studies were to be done today, it may be the case that we would ...
as well as the ability to estimate it accurately. For example, false labels in the test sets would worsen the apparent specificity. Second, although our echocardiography model outperformed experts, the expert had access to only the echocardiography videos and no other clinical information. Thus, thi...
Results This section provides the performance scores on the span and document-level label extraction tasks. Span classification Table 6 shows that for most characteristics, SpanCategorizer achieved the highest weighted and macro F1-scores for the span classification task. However, ALLrule performed part...
The final beat-by-beat prediction and analysis is performed withscripts/beat_analysis.R. This script combines the results from segmentation output insize.csvand the clip-level ejection fraction prediction intest_predictions.csv. The beginning of each systolic phase is detected by using the peak det...
The domain knowledge will also include information on the physiology of the heart. For example, each view in the echo video has a repetitive structure over time. This is due to the cyclic, pumping motion of the heart. Therefore, in most the cases, it may be necessary to view only one ...
