“…19 ). Finally, monitoring with ILR has an advantage of continuous application for a much longer time 14,[20][21][22][23][24] . However; limited memory for real ECG data with storing of overwritten files as frequency histograms has been only partly solved by implementing once-a-day automatic transtelephonic data transmission specifically in asymptomatic patients who may not activate transfer of all necessary ECG recordings.…”

“…Prior studies have shown that longer ECG monitoring can more effectively detect clinically unrecognized recurrent arrhythmias after apparently successful ablation [5][6][7][8][9][10][11][12][13][14] .Which mode of long-term ECG monitoring should be preferred in terms of efficacy, comfort, or costs is not clear. Following catheter ablation for paroxysmal AF, even intermittent self-terminating AF/ AT episodes if recurring in clinically significant quantity, should not be missed by continuous ECG monitoring based on principle of endless loop with automatic arrhythmia detection and trans-telephonic ECG transmission limited to a couple of weeks.…”

Aims. Optimal ECG monitoring in detecting recurrences of atrial fibrillation (AF) or atrial tachycardia (AT) after catheter ablation has not been well established. The purpose of this prospective study was to compare the utility of daily ECG monitoring with episodic card recorder (ECR) vs. periodic monitoring with episodic loop recorder (ELR) for the detection of post-blanking AF/AT recurrences during early (Months 4-6) and late (Months 7-12) periods after catheter ablation for paroxysmal AF. Methods. The study included 105 consecutive patients, who received ECR for 12 months and were instructed to send at least 2 random ECG recordings daily with extra-recordings during symptoms. The patients were simultaneously monitored for one week with ELR at the end of each period (Months 6 and 12). Results. Thirty-one and 12 patients with AF/AT recurrence were identified by means of ECR and ELR, respectively. In patients with complete and valid data, ELR technology was inferior to ECR by detecting AF/AT in 5 (31%) of 16 and 5 (26%) of 19 patients with arrhythmia identified by ECR in the early and late period, respectively. Overall, ELR had a sensitivity of 8/23 (35%) for detecting AF/AT recurrence. There was no single patient with AF/AT recurrence on ELR that would not be known from ECR monitoring. Only 2 patients with arrhythmia recurrence were completely asymptomatic throughout the study period. Conclusion. Daily ECG monitoring with ECR was better than periodic monitoring with ELR in detecting AF/AT recurrences during the follow-up periods. Entirely asymptomatic patients with AF/AT recurrences were rare.

“…Identifi cation of pulmonary vein ectopy as a trigger of AF (Haïssaguerre et al, 1998) became the corner-stone for rhythm control using pulmonary vein isolation (PVI) via catheter ablation (5). Preservation of sinus rhythm with catheter ablation has been reported in up to 70 % patients with paroxysmal and 50 % with persistent AF, so the proportion of patients with AF recurrence still remains relatively high (6). Several protective and risk factors were identifi ed (e.g.…”

AIM: Asymptomatic atrial fi brillation (AF) detection and pulmonary veins isolation (PVI) outcome prediction remain challenging. Our aim was to study the association between apelin and paroxysmal AF in patients undergoing radiofrequency catheter PVI. METHODS: Sixty-three consecutive patients (55 ± 8years, 12 females) with paroxysmal AF without a structural heart disease and implanted ECG loop recorders undergoing PVI and healthy control group of 34 persons (41 ± 9.5years, 21 females) were included. Apelin plasmatic concentrations were measured before and three months after PVI. AF burden was continually assessed for three years. RESULTS: Apelin was signifi cantly decreased in AF patients compared to the healthy controls (0.79 ± 0.09 vs 0.98 ± 0.06 ng/ml; p < 0.00001). Apelin plasmatic concentration of 0.89 ng/ml had 94 % specifi city and 89 % sensitivity for AF prediction with the area under the curve (AUC) of 0.96. After propensity matching to sex, age and comorbidities, apelin concentration was signifi cantly lower in AF group (0.78 ± 0.1 vs 0.99 ± 0.06 ng/ml; p < 0.0001; AUC: 0.97). There was a signifi cant inverse correlation between apelin concentration and AF burden both before and after PVI (Rho =-0.22; p = 0.05) and (Rho =-0.51; p = 0.006), respecti vely. There was no signifi cant association between pre-PVI apelin and PVI long-term outcome. CONCLUSION: In patients without a structural heart disease apelin showed a signifi cant specifi city and sensitivity for AF prediction and inversely correlated with AF burden (Tab.

“…This retrospective study included patients from two cohorts: the Reveal LINQ usability study (ClinicalTrials.gov identifier: NCT01965899), a multicenter single-arm clinical study, and clinical data derived from a single center with extensive experience in evaluating the long-term outcome of AF ablation by means of ICM (Bou Ezzeddine et al, 2015). The patients of both cohorts provided written informed consent, and the study protocols were reviewed and approved by the Human Research Ethics Committee of each participating institution.…”

Heart Rate Variability and Clinical Features as Predictors of Atrial Fibrillation Recurrence After Catheter Ablation: A Pilot Study

Single-procedure catheter ablation success rate is as low as 52% in atrial fibrillation (AF) patients. This study evaluated the feasibility of using clinical data and heart rate variability (HRV) features extracted from an implantable cardiac monitor (ICM) to predict recurrences in patients prior to undergoing catheter ablation for AF. HRV-derived features were extracted from the 500 beats preceding the AF onset and from the first 2 min of the last AF episode recorded by an ICM of 74 patients (67% male; 57 ± 12 years; 26% non-paroxysmal AF; 57% AF recurrence) before undergoing their first AF catheter ablation. Two types of classification algorithm were studied to predict AF recurrence: single classifiers including support vector machines, classification and regression trees, and K-nearest neighbor classifiers as well as ensemble classifiers. The sequential forward floating search algorithm was used to select the optimum feature set for each classification method. The optimum weighted voting method, which used an optimum combination of the single classifiers, was the best overall classifier (accuracy = 0.82, sensitivity = 0.76, and specificity = 0.87). Clinical and HRV features can be used to predict rhythm outcome using an ensemble classifier which would enable a more effective pre-ablation patient triage that could reduce the economic and personal burden of the procedure by increasing the success rate of first catheter ablation.
