Personalized LSTM Models for ECG Lead Transformations Led to Fewer Diagnostic Errors Than Generalized Models: Deriving 12-Lead ECG from Lead II, V2, and V6.

Background And Objective: The prevalence of chronic cardiovascular diseases (CVDs) has risen globally, nearly doubling from 1990 to 2019. ECG is a simple, non-invasive measurement that can help identify CVDs at an early and treatable stage. A multi-lead ECG, up to 15 leads in a wearable form factor, is desirable.

Atrial fibrillation: Utility of CHADS and CHADS-VASc scores as predictors of readmission, mortality and resource utilization.

Background: CHADS and CHADS-VASc scores are widely used for thromboembolic risk assessment in Atrial Fibrillation(AF) cohort, however further utilization to predict outcomes is understudied.

Method: HCUP's National Readmission Data(NRD) 2013 was queried for AF admissions using ICD-9-CM code 427.31 in principal diagnosis field.

The presence of diastolic and systolic dysfunction in patients with impaired relaxation filling pattern.

Background: Impaired relaxation filling pattern in the presence of preserved left ventricular ejection fraction is a common finding which is ascribed to early diastolic dysfunction. We thought to determine the distribution of various markers of systolic and diastolic dysfunction in these patients.

Methods: A total of 106 patients were included in this retrospective observational study.
