该数据集名为Chapman-Shaoxing ECG Windows，是从Chapman-Shaoxing 12-lead ECG Database预处理而来的心电图数据集。包含45,150名患者和180,600个窗口的心电图数据，采样频率为128Hz，窗口大小为4秒（512个样本），重叠比例为50%。数据集分为训练集（126,420个窗口，31,605名患者）、验证集（27,088个窗口，6,772名患者）和测试集（27,092个窗口，6,773名患者）。数据预处理步骤包括提取导联II、带通滤波、重采样、窗口划分、Z-score归一化以及患者级别的分层划分。数据集Schema包含患者ID、记录ID、心电图窗口、二分类和多分类标签等信息。

The dataset is named Chapman-Shaoxing ECG Windows, preprocessed from the Chapman-Shaoxing 12-lead ECG Database. It contains ECG data from 45,150 patients and 180,600 windows, with a sampling frequency of 128Hz, window size of 4s (512 samples), and 50% overlap. The dataset is divided into training set (126,420 windows, 31,605 patients), validation set (27,088 windows, 6,772 patients), and test set (27,092 windows, 6,773 patients). Preprocessing steps include extracting Lead II, bandpass filtering, resampling, windowing, Z-score normalization, and patient-level stratified splitting. The dataset schema includes patient ID, record ID, ECG window, binary and multi-class labels, among others.
