This is a general prototype for machine learning based heartbeat classification. Label each heartbeat in ECG. R peak detection is first performed to locate each heartbeat.
Each heartbeat then will be classified by a CNN. Corresponding label will be printed on the top of each R peak.
The CNN is trained using a few throusand labeled beats. Abbreviations is listed below:
Normal: normal, AAP: Aberrated Atrial Premature, AP: Atrial premature, VE: Ventricular Escape,
NE: Nodal escape, NP: Nodal Premature, LB: Left Bundle Branch Block, RB: Right Bundle Branch Block.
- Tensorflow
- Numpy
- Matplotlib
~$ git clone https://github.com/KChen89/Heartbeat-Classification-based-Diagnosis.git
~$ cd /your folder
~$ python3 hb_classifier.py ecg.dat
~$ python3 hb_classifier.py ECG_sample.dat
The model is trained using ECG sampled at 360 Hz, and length of each beat truncked are pre-defined.
- Beat classification.
- Print labels on top of R peak.
- Combining R peak detection.
- Include more type of beat.
- Other platform (Mobile).
