# 数据集介绍
## 简介
MIT-BIH 心律失常数据库包含 48 个半小时的两通道动态心电图记录摘录，这些记录来自 1975 年至 1979 年间 BIH 心律失常实验室研究的 47 名受试者。从一组 4000 个 24-从波士顿贝斯以色列医院的住院患者（约 60%）和门诊患者（约 40%）的混合人群中收集的小时动态心电图记录；其余 25 个记录是从同一组中选择的，以包括不太常见但具有临床意义的心律失常，这些心律失常在小随机样本中无法很好地表现出来。_x000D_

记录以每通道每秒 360 个样本的速度数字化，在 10 mV 范围内具有 11 位分辨率。两名或多名心脏病专家独立注释每条记录；解决分歧以获得数据库中包含的每个节拍的计算机可读参考注释（总共大约 110,000 个注释）。_x000D_

该目录包含整个 MIT-BIH 心律失常数据库。自 1999 年 9 月 PhysioNet 成立以来，该数据库的大约一半（48 条完整记录中的 25 条，以及所有 48 条记录的参考注释文件）已在此处免费提供。剩下的 23 个信号文件仅在 MIT-BIH Arrhythmia 上可用数据库 CD-ROM，于 2005 年 2 月在此处发布。

# Dataset Introduction
## Overview
The MIT-BIH Arrhythmia Database contains 48 half-hour excerpts of two-channel ambulatory electrocardiogram (ECG) recordings, collected from 47 subjects enrolled in studies at the BIH Arrhythmia Laboratory between 1975 and 1979. The recordings were sampled from a mixed population of 4000 24-hour ambulatory ECG recordings obtained from inpatients (approximately 60%) and outpatients (approximately 40%) at Boston’s Beth Israel Hospital; the remaining 25 recordings were selected from the same cohort to include less common but clinically significant arrhythmias that were not well-represented in the small random sample.

The recordings were digitized at 360 samples per second per channel, with 11-bit resolution over a 10 mV range. Two or more cardiologists independently annotated each recording; disagreements were resolved to obtain computer-readable reference annotations for each beat included in the database (totaling approximately 110,000 annotations).

This archive contains the complete MIT-BIH Arrhythmia Database. Since the launch of PhysioNet in September 1999, approximately half of this database (25 of the 48 complete recordings, plus the reference annotation files for all 48 recordings) has been freely available here. The remaining 23 signal files were only available on the MIT-BIH Arrhythmia Database CD-ROM, which was released here in February 2005.
