ECG-TFDS

Load common open source ECG databases as a Tensorflow dataset. The final format should be ECG signals of one second in length, representing a heartbeat. The R-peaks form the center of the signal, which is normalized in the range $[0, 1]$.

How to get started?

  1. Install the requirements pip install -r requirements
  2. Navigate into the desired dataset folder cd src/dataset/
  3. Build the dataset tfds build

Available Datasets

How to Add a New Dataset?

To incorporate a new dataset into the collection, follow these steps:

  1. Choose an open-source ECG database, e.g., PhysioNet. Ensure that you exclusively select datasets with an appropriate license.
  2. Go to the src folder and execute the following command: 
    tfds new DATASET_NAME
  3. Open and edit the DATASET_NAME/DATASET_NAME_dataset_builder.py file following the provided instructions. Any generic preprocessing steps should be placed in the utils folder.
  4. Include tests in the DATASET_NAME/DATASET_NAME_dataset_builder_test.py file.
  5. Include metadata files: CITATIONS.bib, README.md, and TAGS.txt.
  6. Confirm successful dataset building using the command: 
    tfds build
  7. During your initial complete build, register the checksum with: 
    tfds build --register_checksums
  8. Navigate to ./electrocardiogram and append the dataset to the collection in electrocardiogram.py.
  9. Modify the requirements.txt and this README file accordingly
  10. Create a pull request and provide a concise motivation, description, and dataset metadata, including details like count, size, dataset license, and source.

Ensure adherence to these steps to seamlessly integrate the new dataset into the collection.
