Comparative effectiveness of propafenone and aksaritmin for conversion of paroxysmal atrial fibrillation

With age, the chance of developing AF rises. In 3. 8 percent of people older than 60 years and 9% of people older than 80 years [1], AF is present in 3. 8 percent of people older than 60 years and in 9% of people older than 80 years [1]. Paroxysmal AF raises the risk of stroke to the same degree as other AF [6].

ECGI Periodicity Unraveled: A Deep Learning Approach for the Visualization of Periodic Spatiotemporal Patterns in Atrial Fibrillation Patients

ECGIs from AF patients obtained prior to pulmonary vein isolation are encoded to a lower-dimensional feature space using a 3D-CNN autoencoder, and finally processed with principal component analysis to aggregate recurring patterns and quantify their contribution to the overall spatiotemporal propagation scheme. According to the same, the number of PCs required to explain 90% of variance in ECGI recordings varied from 20 to 90, showing a varying number of propagation patterns across patients, with a higher correlation between patients and inter-segment high than 69%.

Spatial Relationship Between Atrial Fibrillation Drivers and the Presence of Repetitive Conduction Patterns Using Recurrence Analysis on In-Silico Models

Catheter ablation therapy for atrial fibrillation is also suboptimal, owing to the difficulty of identifying AF drivers. In this research, we investigated the spatial relationship between repetitiveness in recurrence analysis and rotor positions in an in-silico AF model. Intervals with and without long-lasting sources within the electrode coverage area were established; the recurrence in both groups of intervals was quantified and compared to each other by determining the recurrence rate per AF cycle length.

High Coverage and High-Resolution Mapping of Repetitive Patterns During Atrial Fibrillation

Patients with persistent atrial fibrillation are candidates for candidate ablation targets for patients with persistent atrial fibrillation. Although most of the atria, high-density mapping electrodes only cover a fraction of the atria, combinating sequential recordings could provide a more complete picture of common repetitive atrial conduction characteristics and enable AF driver localization. Using recurrence plots, we developed a novel algorithm to combine multiple local activation maps into larger composite maps. Pearson correlations were determined between original and reconstructed activation patterns, indicating a correlation between original and reconstructed activation patterns.

Clinical and electrophysiological predictors of device-detected new-onset atrial fibrillation during 3 years after cardiac surgery

We investigated the prevalence and predictors of early and late onset atrial fibrillation in patients undergoing open chest cardiac surgery. An ILR was used in the diagnosis and monitoring of AF in patients undergoing open chest cardiac surgery. POAF affected 46 patients, with early POAF detecting in 27 patients and late POAF in 37 patients. In POAF patients with electrically induced AF, more complicated propagation patterns were observed than in patients without POAF.

Statistical Analysis Plan: Clarithromycin and the Risk of incident Atrial Fibrillation -a secondary analysis of the CLARICOR (clarithromycin for patients with stable coronary heart disease) trial

In patients with stable coronary heart disease, the CLARICOR randomised trial of clarithromycin increased all-cause and cardiovascular mortality of the brief clarithromycin regimen found increased all-cause and cardiovascular mortality. We provide an outline of the correlation between the use of clarithromycin and the CLARICOR trial. Methods The CLARICOR study randomised 4372 patients with stable coronary artery disease in Copenhagen from October 1999 to April 2000 was randomized. We'll see how clarithromycin will reduce the incidence of AF using the Cox proportional hazard method.
