<p>This is a ECG/EKG dataset from the  <a rel="noreferrer nofollow" aria-label="Data for development and evaluation of ECG-based apnea detectors (opens in a new tab)" target="_blank" href="https://physionet.org/physiobank/database/apnea-ecg/">Data for development and evaluation of ECG-based apnea detectors</a></p>

<h1>Content</h1>

<p>It contains 70 <a rel="noreferrer nofollow" aria-label="Electrocardiography (opens in a new tab)" target="_blank" href="https://en.wikipedia.org/wiki/Electrocardiography">Electrocardiography</a> records:</p>

<ul>

<li>Training set<ul>

<li>a01.dat to a20.dat</li>

<li>b01.dat to b05.dat</li>

<li>c01.data to c10.dat</li></ul></li>

<li>Test set <ul>

<li>x01.dat to x25.dat</li></ul></li>

</ul>

<p>The  .dat files contain the digitized ECGs (16 bits per sample, least significant byte first in each pair, 100 samples per second, nominally 200 A/D units per millivolt). </p>

<p>For each a.dat file in the training set there is .apn file that is annotation (by human experts) stating for each minute of recording if there was apnea or not</p>
