Assumption-bounded reduced electro-thermal modeling of lesion formation in radiofrequency cardiac ablation: power–time allocation, thermal latency, perfusion, and temperature limitation Xue Zhou (68629) Lingfeng Lu (10688431) Physical Sciences not elsewhere classified Neuroscience Physiology Mathematical Sciences not elsewhere classified Inorganic Chemistry Electro-thermal model high-power short-duration ablation radiofrequency catheter ablation temperature-limited control thermal latency <p>Radiofrequency ablation comparisons are confounded by energy, latency, perfusion, assumptions, and controller action. An assumption-bounded two-dimensional electro-thermal model compared 30 W/30 s, 50 W/10 s, fixed 90 W/4 s, and temperature-limited 90 W/4 s protocols. A 30 s post-pulse endpoint passed 12/12 cases. Equal-energy peak temperatures differed. In the 4 mm-buffer grid, the limiter reduced power in 29/60 cells. Peak-temperature and protocol-associated perfusion-effect orderings persisted across return-location tests, whereas the presence of the Arrhenius damage contour Ω ≥ 1 and controller intervention were return-sensitive. This supports screening, not absolute or patient-level prediction.</p> 2026-09-29T09:13:14Z Text Journal contribution 10.6084/m9.figshare.34022258.v1 https://figshare.com/articles/journal_contribution/Assumption-bounded_reduced_electro-thermal_modeling_of_lesion_formation_in_radiofrequency_cardiac_ablation_power_time_allocation_thermal_latency_perfusion_and_temperature_limitation/34022258 CC BY 4.0
