MIMIC-III Waveform Database

The MIMIC-III Waveform Database contains 67,830 record sets for approximately 30,000 ICU patients. Almost all record sets include a waveform record containing digitized signals (typically including ECG, ABP, respiration, and PPG, and frequently other signals) and a "numerics" record containing time series of periodic measurements, each presenting a quasi-continuous recording of vital signs of a single patient throughout an ICU stay (typically a few days, but many are several weeks in duration). A [subset of this database](/content/mimic3wdb-matched/) contains waveform and numerics records that have been matched and time-aligned with [MIMIC-III Clinical Database](/content/mimiciii/) records. *[ICU]: Intensive care unit *[ECG]: Electrocardiogram *[ABP]: Arterial blood pressure *[PPG]: PhotoplethysmogramMIMIC-III波形数据库（MIMIC-III Waveform Database）收录了约3万名重症监护病房（Intensive Care Unit，ICU）患者的67830条记录集。几乎所有记录集均包含两类核心内容：其一为波形记录，存储数字化生理信号（通常涵盖心电图（Electrocardiogram，ECG）、有创动脉血压（Arterial blood pressure，ABP）、呼吸信号及光电容积描记图（Photoplethysmogram，PPG），还常包含其他类型生理信号）；其二为“数值”记录，存储周期性测量的时间序列数据。两类记录均为准连续记录了单例患者在ICU住院期间的生命体征，住院时长通常为数天，部分可达数周。本数据库的一个子集（[/content/mimic3wdb-matched/]）收录了已完成匹配与时间对齐的波形记录与数值记录，且这些记录均与MIMIC-III临床数据库（[/content/mimiciii/]）的记录完成匹配及时间对齐。

背景概述

MIMIC-III Waveform Database是一个大型ICU患者生理信号数据库，包含67,830条记录（约30,000名患者）的波形和生命体征数据，总时长超过300万小时。数据主要包括ECG、动脉血压、呼吸和光电容积图等信号，其中约三分之一记录与临床数据库匹配。
