This repo contains MIT-BIH data preprocessing and a sample deep model.
The original data can be found at https://physionet.org/content/mitdb/1.0.0/
(1) Classify ECG heart beats into 5 classes: N, S, V, F, Q
(2) Classify ECG heart beats into 2 classes: V, non-V (need manually modify test_mitdb.label2index)
# (1) unzip raw data
unzip data/mit-bih-arrhythmia-database-1.0.0.zip
# (2) preprocess to get npy
python preprocess.py
# (3) train
python test_mitdb.py
The label-group map is used from ANSI/AAMI EC57: 2012 Testing and reporting performance results of cardiac rhythm and ST segment measurement algorithms, page 8
| Code | Group | Description | 中文 |
|---|---|---|---|
| N | N | Normal beat (displayed as"·" by the PhysioBank ATM, LightWAVE, pschart, and psfd) | 正常 |
| L | N | Left bundle branch block beat | 左束支传导阻滞心搏 |
| R | N | Right bundle branch block beat | 右束支传导阻滞心搏 |
| B | N | Bundle branch block beat (unspecified) | 束支传导阻滞心搏 |
| A | S | Atrial premature beat | 房性早搏，房性期前收缩(心室搏动还未结束新房就开始搏动) |
| a | S | Aberrated atrial premature beat | 异常房性早搏 |
| J | S | Nodal (junctional) premature beat | 交界性早搏 |
| S | S | Supraventricular premature or ectopic beat (atrial or nodal) | 室上性早搏(发生于心房或者房室结的统称为室上性，室上性早搏，是说早搏介于房性和室性之间，属于轻微的心率失常) |
| V | V | Premature ventricular contraction | 室性收缩 |
| r | V | R-on-T premature ventricular contraction | R落在T上的室性早搏 |
| F | F | Fusion of ventricular and normal beat | 心室融合心跳 |
| e | S | Atrial escape beat | 房性逸搏(被动性异位心律) |
| j | S | Nodal (junctional) escape beat | 交界性逸搏 |
| n | S | Supraventricular escape beat (atrial or nodal) | 室上性逸搏 |
| E | V | Ventricular escape beat | 室性逸搏 |
| / | Q | Paced beat | 起搏心搏 |
| f | Q | Fusion of paced and normal beat | 起搏融合心跳 |
| Q | Q | Unclassifiable beat | 未分类心跳 |
| ? | Q | Beat not classified during learning | 其他 |
