“…In our previous research [56], we showed that we can construct a model of the left atrium to reproduce clinical electroanatomical mapping data [57] without incorporating fiber organization. We validated our fiber-independent model We can see that for all the six different pacing scenarios, the average propagation speed values are similar regardless of which fiber organization was implemented.…”

Over the past two decades there has been a steady trend towards the development of realistic models of cardiac conduction with increasing levels of detail. However, making models more realistic complicates their personalization and use in clinical practice due to limited availability of tissue and cellular scale data. One such limitation is obtaining information about myocardial fiber organization in the clinical setting. In this study, we investigated a chimeric model of the left atrium utilizing clinically derived patient-specific atrial geometry and a realistic, yet foreign for a given patient fiber organization. We discovered that even significant variability of fiber organization had a relatively small effect on the spatio-temporal activation pattern during regular pacing. For a given pacing site, the activation maps were very similar across all fiber organizations tested.

“…In our previous research [56], we showed that we can construct a model of the left atrium to reproduce clinical electroanatomical mapping data [57] without incorporating fiber organization. We validated our fiber-independent model with data from 15 patients and the performance was good: the average absolute LAT error was 5.47 ms for sinus rhythm and 10.97 ms for flutter and tachycardia, and the average correlation was 0.95 for sinus rhythm and 0.81 for flutter and tachycardia.…”

“…At present, radiofrequency ablation is the preferred method for the treatment of atrial fibrillation, with the goal of restoring sinus rhythm, controlling ventricular rate and preventing thrombosis [4]. In radiofrequency catheter ablation, a model of the left atrium is constructed using a threedimensional electrophysiological mapping system.…”

Objective: To explore the application effect of multi-dimensional nursing combined with the Global Registry of Acute Events (GRACE) scoring system in the nursing of patients with atrial fibrillation after radiofrequency ablation with green precision catheter radiofrequency ablation. Methods: A total of 274 patients diagnosed with atrial fibrillation undergoing green precision catheter radiofrequency ablation were collected from the Department of Cardiology at our hospital in a retrospective study. After the inclusion, exclusion, diagnostic criteria and physical examination, all the subjects underwent green precision catheter radiofrequency ablation. According to various nursing methods that were adopted, they were divided into two groups with 7–14 days of nursing intervention by digital randomization: the study group (multi-dimensional nursing combined with GRACE scoring system evaluation, n = 136 cases) and the control group (postoperative routine nursing, n = 138 cases). The MOS item short from health survey (SF-36) score, Hamilton anxiety scale (HAMA) score, Hamilton depression scale (HAMD) score, complication rates and the nursing quality of the two groups were observed. Results: After multi-dimensional nursing combined with the GRACE in-hospital scoring system for stratified nursing in the study group, SF-36 scores in both groups increased after conventional nursing in the control group, but there was a statistical difference between the study group and the control group (p < 0.05). HAMA score and HAMD score decreased, and there were statistical differences between the study group and the control group (p < 0.05). The comparison between the study group and the control group showed that “Cardiac tamponade”, “Atrioventricular block”, “Peripheral vascular injury” and the total incidence of complications were statistically different (p < 0.05). The basic satisfaction, number of satisfaction and total satisfaction rate of the study group were higher than those of the control group, and the difference was statistically significant (p < 0.05). Conclusions: Multi-dimensional nursing combined with the GRACE scoring system in the nursing care of patients with atrial fibrillation after radiofrequency ablation with the green precision catheter, improves the quality of life, alleviates negative emotions, reduces the incidence of complications, and results in better quality of nursing care.
