Model prediction of initial tachycardic episode using external control data matched for every episode of tachycardia. Comparison of a model trained on MIMIC-II data to identify an initial episode of tachycardia (heart rate (HR) > 130/min) in an external validation cohort from that same database. Results are shown as risk score changes over time as the future tachycardic and non-future tachycardic (control) groups move toward the event. The control group’s time series data were time-matched to correspond to the future tachycardic group’s time in the ICU. Data derived from Yoon et al. [43].
