Icentia11k Dataset

Overview

This dataset consists of ECG recordings from 11,000 patients and 2 billion labelled beats. The data was collected by the CardioSTAT, a single-lead heart monitor device from Icentia. The raw signals were recorded with a 16-bit resolution and sampled at 250 Hz with the CardioSTAT in a modified lead 1 position. We provide derived version of the dataset where each patient is stored in separate HDF5 files on S3. This makes it faster to download as well as makes it possible to leverage TensorFlow prefetch and interleave to parallelize data loading.
