[en] THE BUILDING OF A MAGNETOCARDIOGRAPHER AND PROPOSAL OF A MULTIPLE DIPOLE CARDIAC MODEL IN MAGNETOCARDIOGRAPHY / [pt] CONSTRUÇÃO DE UM MAGNETOCARDIÓGRAFO E PROPOSTA DE UM MODELO DE MÚLTIPLOS DIPOLOS EM MAGNETOCARDIOGRAFIA

IRADJ ROBERTO EGHRARI 22 January 2007 (has links)
[pt] Foi construído um magnetocardiógrafo supercondutor utilizando-se um SQUID (Superconductor Quantum Interference Device), capaz de medir campos magnéticos da ordem de 10 -8 gauss. Este aparelho foi utilizado para se testar a validade de um modelo cardíaco de múltiplos dipolos para magnetocardiografia. O modelo foi implementado através de um simulador elétrico e os resultados são comparados com sinais magnetocardiográficos de indivíduos normais. / [en] A superconducting magnetocardiographer using a SQUID (Superconductor Quantum Interference Device) which is capable of measuring magnetic fields down to 10 -8 gauss was built. This instrument was used in the test of a multiple dipole cardiac model in magnetocardiography. The model was accomplished through an electric simulator and the results are compared with magnetocardiographic signals of normal subjects.
