impedance cardiography การใช้

A similar correlative study was performed during the Cosmos 1514 mission, where blood flow velocity was compared to total body cardiac output as determined by impedance cardiography.
Impedance cardiography ( often abbreviated as ICG, or Thoracic Electrical Bioimpedance ( TEB ) ) measures changes in electrical impedance across the thoracic region over the cardiac cycle.
In his spare time, Webster works with undergraduate biomedical engineering design teams at the University of Wisconsin-Madison, including ongoing projects with impedance cardiography and atrial fibrillation.
A project undertaken in the laboratory of cardiac physiologist William V . Whitehorn in the late 1940s led to Perl s first scientific paper, published in " Science " in 1949; the principles behind the device Perl designed for this project became the foundation for impedance cardiography.
