Unshielded magnetocardiography: Repeatability and reproducibility of automatically estimated ventricular repolarization parameters in 204 healthy subjects

摘要

Magnetocardiographic mapping ( ) provides quantitative assessment of the magnetic field ( ) induced by cardiac ionic currents, is more sensitive to tangential currents, and measures vortex currents undetectable by , with higher reported sensitivity of ventricular repolarization (VR) parameters for earlier detection of acute myocardial ischemia. Aims of this study were to validate the feasibility of in‐hospital unshielded and to assess repeatability and reproducibility of quantitative parameters, considering also possible gender‐ and age‐related variability.
