ECG Record Table

This table lists all records in the MIMIC-IV-ECG module. Each diagnostic ECG study has a waveform file (in WFDB format) and is assigned a unique study_id. This table contains the path (path) to the waveform file. The study_id can be used to link to the machine measurement and note information in the other lookup tables.

Important considerations

• Diagnostic ECGs are available for patients from the MIMIC-IV Clinical Database. These ECGs were collected between 2008 - 2019 but have been date shifted (for de-identification) per the convention across MIMIC.
• For a given subject, all available diagnostic ECGs (inpatient and outpatient) were pulled. Therefore, a large number of the waveforms will overlap with visits in the Clinical Database but some will not.

Table columns

subject_id

subject_id is a unique identifier which specifies an individual patient. Any rows associated with a single subject_id pertain to the same individual.

study_id

A unique identifier for the diagnostic ECG study.

file_name

The name of the .hea and .dat WFDB files for a given study.

ecg_time

The time that the diagnostic ECG was collected.

path

The path to the waveform file.
