Evaluation of ECG signal classification performance using the PTB-XL dataset under the Natural Distribution setting, reporting classification accuracy and communication overhead.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Electrocardiography Classification |
| Dataset (including any stated split) | PTB-XL Natural Distribution |
| Metric | Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 9 of 9 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Accuracy](<https://www.sota2.com/research/sota/electrocardiography-classification-on-ptb-xl-natural-distribution.md?metric=Accuracy>): Higher is better; unit: PERCENT.

- [Communication Overhead (MB)](<https://www.sota2.com/research/sota/electrocardiography-classification-on-ptb-xl-natural-distribution.md?metric=Communication%20Overhead%20(MB)>): Lower is better; unit: SIZE.
