Feasibility of novel unshielded portable magnetocardiography: Insights from the prospective multicenter MAGNETO-SCD trial.

Sudden cardiac death(SCD) causes >4million deaths globally/year, predominantly through ventricular arrhythmia(VA)1 caused by vulnerable-substrate via heterogenous conduction during cardiac-depolarisation/repolarization and survival is poor. 1 Current risk-stratifiers using cardiac-imaging/ECG are sub-optimal.1 Magnetocardiography(MCG) may be superior in detecting SCD/VA-risk,2,3,4 however, its use has been limited by significant financial/logistic restrictions.
