It will be of interest to learn whether measures that reverse cardiac steatosis overturn the abnormal late potentials. The role of elevated free fatty acids in the development of cardiac arrhythmias has been explored by others (1–3); this may be a primary cause of abnormal late potentials in individuals with type 2 diabetes or the metabolic syndrome.Dr. Leslie points out that Austin Flint described fatty heart disease almost 150 ...References1.
