IITB-ICG:
An Impedance Cardiography (ICG) Database with Doppler Echocardiography as the
Reference
Abstract
Impedance
cardiography (ICG) is a noninvasive technique for sensing the thoracic
impedance variation due to blood volume variation during the cardiac cycle, and
using the sensed impedance to estimate stroke volume (SV) and other
cardiovascular indices. The IITB-ICG database was prepared as part of a
research project at IIT Bombay (Mumbai, India) to develop techniques for
detecting ICG characteristic points and beat-to-beat estimation of stroke
volume using Doppler echocardiography as the reference technique. The database
comprises simultaneous recordings of ICG signals and Doppler echocardiograms
from 18 subjects with normal health and 22 with cardiovascular disorders.
Signals for subjects with normal health (SNH) were recorded under two
conditions: at rest and after an exercise to induce significant beat-to-beat
variability. Signals for subjects with cardiovascular disorders (SCD) were
recorded only at rest. Each SNH recording has data for 630 and 625 cardiac
cycles for the under-rest and post-exercise conditions, respectively, and each
SCD recording has data for 842 cardiac cycles for the under-rest condition. The
data files provide physical measurement data, ICG signals at 500 Hz, echocardiography
images, and beat-to-beat SV measurement carried out manually from the Doppler
echocardiograms.
