Repeated heart recordings improved AI risk prediction in patients

Across three hospital cohorts, models using repeated heart recordings outperformed a single-recording model for 11 of 13 outcomes.Across three hospital cohorts, models using repeated heart recordings outperformed a single-recording model for 11 of 13 outcomes.
