MIMIC-III-Ext-CA: a MIMIC-III Derived Dataset of Cardiac Arrests in Photoplethysmographs

Photoplethysmography (PPG) is increasingly considered for detecting out-of- hospital cardiac arrest (OHCA), but publicly available datasets remain scarce. We used a method for identifying cardiac arrest episodes captured by PPG in the MIMIC-III database, which combines automated screening with manual annotation of waveforms and clinical data. Using this approach, we compiled 36 annotated cardiac arrest episodes from 31 patients. The dataset serves as a valuable resource for developing and validating wearable OHCA detection technologies.
