Editorial: Current proceedings in magnetocardiology—past, present, future

Figure 1. Black dotted line represents the action potential. Red area represents the monopolarity index (instantaneous percentage of monopolar currents). Ordinate shows the scaling of magnetic field strength. Double blue arrows indicates the time interval where Ca2 + transient flows. The figure illustrates examples of Ca2 + transient dysfunction in various diseases (B–E) and in a healthy state (A) Ca2 + transients are shown in green. Dysfunctional Ca2 + transient is characterized by Ca2 + transient max suppression (B–E), desynchronity between Ca2 + transient max and action potential Tmax (B,D,E), and reduced Ca2 + uptake velocity (B,D,E). A. Healthy (26yrs, male, marathon runner); B. Old age (76yrs, male, healthy); C. Insulin dependent Diabetes mellitus (76yrs, male); D. HFrEF (46yrs, male); E. Post COVID disease (56yrs, female).
