Ergometer device magnetocardiography and for the same

摘要

Device magnetocardiography for preparing magnetocardiograms load, comprising a magnetocardiógrafo (1) and a loading unit (2) composed of non-magnetic components, preparing the magnetocardiógrafo (1) and load unit (2) in a chamber shielding (4) for protection against external magnetic fields, being or the loading unit (2) an ergometer braking bicycle by gas under pressure or a gas mixture under pressure from a source (6) arranged outside comprising chamber shield (4) for gas under pressure or the gas mixture under pressure, and the loading unit (2) an inertial mass (19) movable in rotation comprising with a mechanism (38) actuating manually or pedal with a transmission ratio of at least 1:10 and a brake unit (20) operable by gas under pressure or the gas mixture under pressure, for braking rotation of the inertial mass (19), adjusting the braking force of the brake unit (20) by the gas under pressure or the gas mixture under pressure.
