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 contains waveform and numerics records that have been matched and time-aligned with MIMIC-III Clinical Database records.

MIMIC-III波形数据库囊括了约30,000位重症监护病房（ICU）患者共计67,830条记录集。几乎所有记录集中均包含一个波形记录，该记录含有数字化信号（通常包括心电图（ECG）、平均动脉压（ABP）、呼吸和光电容积描记图（PPG）等，以及经常包含的其他信号），以及一个包含周期性测量时间序列的“数值”记录，每一项记录均呈现了一位患者在ICU期间（通常为数日，但也有部分为几周）生命体征的准连续记录。该数据库的一个子集包含了与MIMIC-III临床数据库记录相匹配并时间对齐的波形和数值记录。

背景与挑战

背景概述

MIMIC-III波形数据库是一个大规模ICU生理信号数据集，包含67,830条记录集，涉及约30,000名ICU患者，每条记录集通常包括波形记录（如ECG、ABP、呼吸和PPG信号，采样频率125 Hz）和数值记录（生命体征时间序列），记录了患者整个ICU住院期间的连续数据。该数据库是MIMIC-III临床数据库的伴侣，其中约三分之一记录（22,000条记录，来自10,000名患者）可与临床数据库匹配，为重症监护研究提供了丰富的多模态生理信号资源。
