Key result
Extrasystole is linked to ~35% lower temporal rhythm expectation vs conditional norm.
Why the study?
Discrete mathematical models combining cyclic discrete random process theory with amplitude-temporal characteristics of P, Q, R, S, and T waves were developed to enable comprehensive assessment of electrocardiographic signals.
Does mathematical modeling of electrocardiographic signals using temporal rhythm and amplitude variability functions differentiate between conditional norm and extrasystole in patients?
Does mathematical modeling of electrocardiographic signals using temporal rhythm and amplitude variability functions differentiate between conditional norm and extrasystole in patients?
Combining cyclic discrete random process theory with amplitude variability and temporal rhythm functions of ECG waves shows high sensitivity to pathological changes in extrasystole, increasing amplitude variability variance by 5 to 6 orders of magnitude compared to normal signals.

May aid ECG variability modeling for extrasystole; leaves open clinical utility pending prospective validation.
Presents discrete mathematical models for electrocardiographic signal (ECS) analysis based on temporal rhythm functions and amplitude variability of characteristic waves P, Q, R, S, T. The proposed approach combines cyclic discrete random process theory with amplitude-temporal characteristics to enable comprehensive assessment of cardiac signals. Experimental validation on patients with conditional norm and extrasystole demonstrates high sensitivity to pathological changes, with variance increasing by 5-6 orders of magnitude for amplitude variability in pathological cases.

Mosiy et al. (2025) studied Extrasystole. Extrasystole vs. Conditional norm was evaluated on Electrocardiographic signal amplitude variability and temporal rhythm statistical characteristics (mathematical expectation and variance). Extrasystole increased ECG amplitude variability variance by 5-6 orders of magnitude (78.44-719.20 vs 0.00010-0.00022 mV²) and reduced temporal rhythm expectation by 35% vs conditional norm.
