Is the activation potential of Mahaim pathway always a fast potential?
Our results illustrated that the activation potential of Mahaim pathways is not always a fast potential. One-third of Mahaim pathways can be mapped and ablated when the slow type of M-potential was used as a target for ablation. We also confirmed high efficacy of catheter ablation of Mahaim pathways guided by activation potentials.
These data suggest an altered hepatic management of APOA1 and that cysteine may be involved in the control of this apolipoprotein at this level. Overall these findings represent a new aspect of dietary regulation of HDL at the hepatic transendothelial transport.
