Atrial fibrillation (AF) is the most common heart rhythm disorder requiring treatment and is associated with an increased rate of hospitalization and death. When choosing the tactics of restoring and maintaining sinus rhythm in most patients with AF paroxysm without pronounced organic heart damage, the drug of choice is propafenone, which has a high level of safety and efficacy. The use of the drug within the framework of a «pill in a pocket» by the patient himself, intravenously in a day hospital of an outpatient medical institution or by an ambulance team allows stopping AF paroxysm in most patients at the prehospital stage. Propafenone is also the drug of choice for inpatient sinus rhythm restoration and for long-term antiarrhythmic therapy in a wide range of patients with AF.

Abstract Background Catheter based ablation therapy is an established treatment in patients with symptomatic atrial fibrillation (AF). Currently, the detection of AF recurrences after AF ablation is most frequently performed by short continuous heart rhythm monitoring, such as Holter monitoring. Our aim is to evaluate the effectiveness and accurateness of long-term intermittent rhythm monitoring using a single-lead ECG (AliveCor Kardia®) compared to short continuous monitoring with Holter for the detection of AF recurrences after ablation. Methods We conducted a prospective study of patients after AF ablation between May 2017 and October 2019. As standard of care, patients underwent Holter monitoring (minimum 24 hours) at 3, 6 and 12 months after ablation. At the same time patients were instructed to use an AliveCor Kardia (ACK) monitor to record a 30-second ECG three times a day and in case of symptoms for a period of four weeks. The primary endpoint was the difference in proportion of AF recurrences detected by ACK compared to Holter. Secondary endpoint was the sensitivity and specificity of ACK algorithm. Further, patients were asked to complete a questionnaire on the System Usability Scale to evaluate the usability for both ACK and Holter. Results Out of 126 post-ablation patients, 115 (91%) patients (35 female, age 63±8 years) transmitted their ACK recordings and were included in this analysis. A total of 7838 ECGs were assessed. The mean AKC usage time was 27+11 days, mean number of recordings 68+28 per patient. Our primary endpoint, the proportion of detection of recurrent AF, was almost twice as high in ACK (24%) than in Holter (14%, p<0.05). The ACK algorithm categorized 80% as normal sinus rhythm, 10% as possible AF, 10% as unclassified and 0.6% as unreadable. According to the interpretation of the researchers' team, 38 (0.5%) ECGs were uninterpretable and in 98% of the unclassified ECGs by ACK, the researchers' team was able to establish a diagnosis. The ACK diagnostic algorithm displayed a sensitivity of 95% and specificity of 98% for AF detection. The ACK diagnostic algorithm had a high likelihood of misclassifying premature atrial contractions and sinus rhythm accompanied by artifacts as AF (6.8% and 11% of all recordings assessed by AKC as AF, respectively). Based on the System Usability Scale, patients rated ACK as more acceptable in daily usage than Holter (75.0% versus 58.6% had an overall score above 70%, respectively). Conclusions ACK effectively and accurately detects AF recurrences in patients who underwent AF ablation and has a high patients' acceptability compared to Holter monitoring. Long-term intermittent rhythm monitoring may provide a promising tool for rhythm follow-up after AF ablation procedures.

Abstract Aims Mobile, portable ECG-recorders allow the assessment of heart rhythm in out-of-hospital conditions and may prove useful for monitoring patients with cardiovascular diseases. However, the effectiveness of these portable devices has not been tested in everyday practice. Methods and results A group of 98 consecutive cardiology patients (62 males [63%], mean age 69 ± 12.9 years) were included in an academic care centre. For each patient, a standard 12-lead electrocardiogram (SE), as well as a Kardia Mobile 6L (KM) and Istel (IS) HR-2000 ECG were performed. Two groups of experienced physycians analyzed obtained recordings. After analyzing ECG tracings from SE, KM, and IS, quality was marked as good in 82%, 80%, and 72% of patients, respectively (p < 0.001). There were no significant differences between devices in terms of detecting sinus rhythm (SE [60%, n = 59], KM [58%, n = 56], and IS [61%, n = 60]; SE vs KM p = 0.53; SE vs IS p = 0.76) and atrial fibrillation (SE [22%, n = 22], KM [22%, n = 21], and IS [18%, n = 18]; (SE vs KM p = 0.65; SE vs IS = 0.1). KM had a sensitivity of 88.1% and a specificity of 89.7% for diagnosing sinus rhythm. IS showed 91.5% and 84.6% sensitivity and specificity, respectively. The sensitivity of KM in detecting atrial fibrillation was higher than IS (86.4% vs. 77.3%), but their specificity was comparable (97.4% vs. 98.7%). Conclusion Novel, portable devices are useful in showing sinus rhythm and detecting atrial fibrillation in clinical practice. However, ECG measurements concerning conduction and repolarisation should be clarified with a standard 12-lead electrocardiogram.

IntroductionPulmonary vein isolation (PVI) is an important treatment for atrial fibrillation (AF). However, many patients need more than one procedure to maintain long-term sinus rhythm. Even after two PVIs some may suffer from AF recurrences. We aimed to identify characteristics of patients who fail after two PVI procedures.Methods and resultsWe included 557 consecutive patients undergoing a first PVI procedure with a second-generation 28 mm cryoballoon. Follow-up procedures were performed using radiofrequency ablation targeting reconnected PVs only. Recurrent AF was defined as any episode of AF lasting >30 s on ECG or 24 hour Holter monitoring performed at 3, 6 and 12 months post procedure. Mean age was 59.1±10.2 years, 383 (68.8%) were male, 448 (80.4%) had paroxysmal AF and the most common underlying condition was hypertension (36.6%). A total of 140/557 (25.1%) patients underwent redo procedure with PVI only. Of these patients 45 (32.4%) had recurrence of AF. These patients were comparable regarding age and sex to those in sinus rhythm after one or two procedures. Multivariate logistic regression showed that non-paroxysmal AF (OR 1.08 (95% CI 1.01 to 1.15), estimated glomerular filtration rate (OR 0.96, 95% CI 0.94 to 0.99), bundle branch block (OR 4.17, 95% CI 1.38 to 12.58), heart failure (OR 4.17, 95% CI 1.38 to 12.58) and Left Atrium Volume Index (OR 1.04, 95% CI 1.01 to 1.08) were associated with AF recurrence after two PVIs. The area under the curve for the identified risk factors was 0.74.ConclusionsUsing a PVI-only approach, recurrence of AF after two AF ablation procedures is associated with more advanced underlying disease and persistent types of AF.

Abstract Aims Restoring sinus rhythm (SR) by ablation alone is an endpoint used in radiofrequency (RF) ablation for long-standing persistent atrial fibrillation (AF) but not with cryotherapy. The simultaneous use of two cryotherapy catheters can improve ablation efficiency; we compared this with RF ablation in chronic persistent AF aiming for termination to SR by ablation alone. Methods and results Consecutive patients undergoing their first ablation for persistent AF of >6 months duration were screened. A total of 100 participants were randomized 1:1 to multi-catheter cryotherapy or RF. For cryotherapy, a 28-mm Arctic Front Advance was used in tandem with focal cryoablation catheters. Open-irrigated, non-force sensing catheters were used in the RF group with a 3D mapping system. Pulmonary vein (PV) isolation and non-PV triggers were targeted. Participants were followed up at 6 and 12 months, then yearly. Acute PVI was achieved in all cases. More patients in the multi-catheter cryotherapy group were restored to SR by ablation alone, with a shorter procedure duration. Sinus rhythm continued to the last available follow-up in 16/49 patients (33%) in the multi-catheter at 3.0 ± 1.6 years post-ablation and in 12/50 patients (24%) in the RF group at 4.0 ± 1.2 years post-ablation. The yearly rate of arrhythmia recurrence was similar. Conclusion Multi-catheter cryotherapy can restore SR by ablation alone in more cases and more quickly than RF ablation. Long-term success is difficult to achieve by either methods and is similar with both.

Objective. To study the effect of preoperative atrial fibrillation (AF) on the risk of stroke and long-term mortality after Off Pump Coronary Artery Bypass (OPCAB). Materials and methods. A retrospective analysis of the results of OPCAB in 212 patients with coronary artery disease (CAD), who were operated on from May 2009 to November 2013, was carried out. After propensity score matching, patients were divided into 2 groups: Group I 82 patients with sinus rhythm (SR) before surgery, Group II (control) 102 patients with AF before surgery. The average age of the included patients was 61 6.7 years, with 95 % CI: 6062. Fifty-four (29.3 %) patients were over 65 years of age. There were 162 men (88 %) and 22 women (12 %). The median follow-up was 93.5 (66.7102.0) months. Results. The time spent in the clinic was statistically significantly shorter in the SR group than in the AF group (10 (911) and 14 (1116) hours, respectively, p 0.001). There was no statistically significant difference in the number of perioperative myocardial infarctions (in the group with SR it occurred in 1 (1.2 %) patient, in the group with AF 2 (2 %), p = 0.7), strokes (in the group with SR 1 (1.2 %), in the group with AF 3 (2.9 %), p = 0.6), as well as a 30-day mortality (in the group with SR it was 0 %, in the group with AF 3 (2.9 %), p = 0.2). In the long-term postoperative period, there were statistically significantly fewer strokes in the group with SR than in the group with AF (in the group with SR, the 10-year stroke freedom was 88.8 %, and in the group with AF 71.8 %, p = 0.018), and also better long-term survival in the group with sinus rhythm (in the group with SR, the 10-year survival rate was 79 %, in the group with AF 63.9 %, p = 0.016). Conclusions. In the group with preoperative AF, the frequency of distant strokes and deaths is higher than in patients with sinus rhythm.
