Atrial fibrillation (AFib) is diagnosed by analysis of the morphological and rhythmic properties of the electrocardiogram. It was recently shown that accurate detection of AFib is possible using beat-to-beat interval variations. This raises the question of whether AFib detection can be performed using a pulsatile waveform such as the Photoplethysmogram (PPG). The recent explosion in use of recreational and professional ambulatory wrist-based pulse monitoring devices means that an accurate pulse-based AFib screening algorithm would enable large scale screening for silent or undiagnosed AFib, a significant risk factor for multiple diseases...

INTRODUCTION: Atrial fibrillation (AFib) is related to a high risk of stroke. The main role in etiopathogenesis is played by the left atrial appendage (LAA). As many as 95 % of thrombi in nonvalvular atrial fibrillation are located in the appendage. Prevention of stroke then consists in permanent anticoagulation which, however, has its limits and risks. An alternative method is the left atrial appendage occlusion. In our report, we would like to present a new possibility of the closure using the epicardial system AtriClip (AtriCure)...

Atrial fibrillation (AFib) is a significant healthcare problem caused by the uneven and rapid discharge of electrical signals from pulmonary veins (PVs). The technique of radiofrequency (RF) ablation can block these abnormal electrical signals by ablating myocardial sleeves inside PVs. Catheter contact force measurement during RF ablation can reduce the rate of AFib recurrence, since it helps to determine effective contact of the catheter with the tissue, thereby resulting in effective power delivery for ablation...

BACKGROUND: Rivaroxaban has gained popularity as an anticoagulant (AC) for stroke prevention in nonvalvular atrial fibrillation (afib) and venous thromboembolism (VTE). Although adverse bleeding events are associated with all AC, lack of point of care testing to measure the effect of rivaroxaban in emergent situations has contributed to perceived increased risk amongst physicians. METHODS: To describe a single center experience with trauma and emergency general surgery (EGS) patients taking rivaroxaban and evaluate outcomes compared with patients taking warfarin using a propensity score analysis...

BACKGROUND: Catheter ablation of atrial fibrillation (AFib) primarily relies upon pulmonary vein isolation (PVI), but such procedures are associated with significant X-ray exposure. The newer Epoch system has been developed so as to enable more precise magnetic navigation whilst limiting X-ray exposure. OBJECTIVES: This study was aimed at quantifying both exposure time and X-ray reduction with the newer Epoch system compared to Niobe II during AFib ablation procedures...

Background: Atrial fibrillation (Afib) patients are at an increased risk of stroke. Patients at moderate to high risk of stroke typically receive antithrombotics, placing them at an increased risk of bleeding. The HAS-BLED tool has been validated in Afib patients receiving warfarin for prediction of major bleeding events. Although HAS-BLED has been researched in patients receiving warfarin, this tool has not been validated with the novel anticoagulant rivaroxaban. Methods: The trial design was retrospective case-control approved by the Institutional Review Board at University of Tennessee Medical Center...

BACKGROUND: Each encounter of asymptomatic individuals with the healthcare system presents an opportunity for improvement of cardiovascular disease (CVD) awareness and sudden cardiac death (SCD) risk assessment. ECG sign deep terminal negativity of the P wave in V1 (DTNPV1) was shown to be associated with an increased risk of SCD in the general population. OBJECTIVE: To evaluate association of DTNPV1 with all-cause mortality and newly diagnosed atrial fibrillation (AFib) in the large tertiary healthcare system patient population...

In this paper, a novel method to detect atrial fibrillation from a seismocardiogram (SCG) is presented. The proposed method is based on linear classification of the spectral entropy and a heart rate variability index computed from the SCG. The performance of the developed algorithm is demonstrated on data gathered from 13 patients in clinical setting. After motion artefact removal, in total 119 minutes of AFib data and 126 minutes of sinus rhythm data were considered for automated atrial fibrillation detection...

BACKGROUND: Clinical trials raised concern that ibrutinib may increase the risk of atrial fibrillation/flutter (Afib/Aflutter) and major bleeding. However, the association has not been statistically validated, and there is no consensus regarding optimal management of anticoagulation among patients receiving ibrutinib who develop Afib/Aflutter. We performed a systematic review and pooled analysis to precisely assess the risk of Afib/Aflutter and bleeding associated with ibrutinib treatment in patients with hematologic malignancies...

BACKGROUND: It has been widely reported that anticoagulants (ACs) are underused for primary and secondary prevention of ischemic stroke in patients with atrial fibrillation (AFib). Furthermore, precise evidence-based guidelines about the best timing for AC initiation after acute stroke are currently lacking. METHODS AND RESULTS: In this retrospective, observational study, we analyzed prescription trends in AFib patients with acute ischemic stroke who were hospitalized in four neurologic stroke units of our region (Lombardia, Italy)...

BACKGROUND: Left ventricular lead (LVL) implant success rates have historically ranged between 70.5% and 95.5%. To date, there are few large studies that evaluate LVL implant success utilizing a single family of delivery catheters and leads. The Attain Success study was a prospective nonrandomized multicenter global study with the main objectives of assessing single-system LVL implant success and complication rates. METHODS: Patients undergoing cardiac resynchronization therapy implantation were eligible for enrollment...

OBJECTIVE: Atrial fibrillation (AFib) is linked to increased risks of mortality and cardiovascular disease. There are several prospective studies examined the association of smoking and metabolic syndrome (Mets) with incident AFib in a general population. No study examined the combination of smoking and Mets on the AFib risk in a general population. We investigated whether the combination of smoking and Mets increased the risk of incident AFib in an urban Japanese population. DESIGN AND METHOD: The 6,901 Suita Study participants (30-84 years old) were initially free of AFib and prospectively followed up for incident AFib...

OBJECTIVE: Timely detection of atrial fibrillation (AF) may effectively prevent cardiovascular consequences. However, traditional diagnostic tools are either poorly reliable (pulse palpation) or not readily accessible (electrocardiogram, ECG) in the general practice. We tested whether an automatic oscillometric blood pressure (BP) monitor embedding an algorithm for AF detection might be effective for opportunistic screening of asymptomatic AF in the community. DESIGN AND METHOD: 220 consecutive subjects from an unselected sample of individuals of a small Italian community were screened using a Microlife WatchBP Office BP monitor with patented AFIB algorithm...
