Clinical Data

This directory contains all data whose origin is related to clinical signals.

  • Dog Heart recordings of heart pressures and ECG from anesthetized dog. For the ECG, values are signed integer values directly from the A/D converter (12 bits). Such a file has a duration of 360s and was digitized by considering a sampling rate of 1 kHz. This file has data acquired from 3 channels, namely: #1 the left ventricular pressure (mm Hg); #2 left aortic pressure (mm Hg); and #3 electrocardiogram (ECG). We wishes to thank Erik Traasdahl of the Department of Medical Physiology at the University of Tromso, Norway.
  • Human Electrocardiogram (ECG) recorded from a human (male) in a supine position. For the ECG, values are signed integer values directly from the A/D converter (12 bits). Such a file has a duration of 180s (approximately, 180k samples) and has been acquired by considering a sampling rate of 1 kHz. We wishes to thank Erik Traasdahl of the Department of Medical Physiology at the University of Tromso, Norway.
  • Blood Flow recorded from the descending aorta of a lamb by using a continuous-Doppler ultrasound. Such a file has a duration of 17.69s, was acquired by considering a sampling rate of 22 kHz, and an A/D converter of 8 bits. We wishes to thank Taha Kadado at the University of Missouri, Kansas City.
