Electrophysiological markers of early myocardial dysfunction in young adults: a biophysical perspective

Early myocardial dysfunction may develop long before the appearance of clinically detectable cardiovascular disease, particularly in young adult populations. At this stage, structural changes are often minimal, while functional and regulatory alterations already affect cardiac performance. Electrophysiological activity of the myocardium reflects these early disturbances through subtle changes in cardiac signal dynamics and regulatory stability. This study examines electrophysiological markers associated with early myocardial dysfunction from a biophysical perspective. Cardiac electrical activity parameters were analyzed to evaluate myocardial responsiveness and regulatory balance under resting conditions. Emphasis was placed on functional signal characteristics rather than overt pathological findings. The analysis revealed distinct electrophysiological patterns suggestive of reduced myocardial functional reserve, even in individuals without apparent clinical symptoms. The results indicate that electrophysiological markers provide sensitive indicators of early myocardial dysfunction. Biophysical interpretation of cardiac electrical signals may therefore enhance early risk identification and support preventive cardiovascular assessment in young adult populations.
