Performance of a Novel Unshielded Magnetocardiography Device in a First-in-Human Study

Magnetocardiography (MCG) is a non-contact measurement of magnetic fields generated by the heart’s electrical currents, represented by Magnetic Field Maps (MFMs). It is effective in detecting coronary ischemia and NSTEMI. Despite the advantages of MCG, adoption has been limited due to poor usability and high costs. We designed and built a novel bedside MCG device that measures cardiac magnetic fields without the limitations of magnetic shielding or cryogenics, and tested the performance of this prototype at a hospital in a first-in-human study.

Objective: We aimed to characterize the safety and technical feasibility of the device, prominence of cardiac features in the average waveforms, and evaluate background interference rejection.
