How to prevent atrial-oesophageal fistula following ablation of atrial fibrillation: are there actually any effective methods?
No full textManifest cardiac memory after biventricular pacing in a super-responder patient: Is memory the sign of a ‘forgotten’ electrical ventricular pattern?
No full textAbstractWe present the case of a super-responder patient with a basal left bundle branch block, who underwent cardiac resynchronization therapy and showed, during biventricular pacing, typical electrocardiographic signs of cardiac memory
Role of cardiac electronic implantable device in the stratification and management of embolic risk of silent atrial fibrillation: are all atrial fibrillations created equal?
No full textIntroduction: Ischemic strokes may be associated with atrial fibrillation (AF). AF detection is critical in ischemic stroke survivors, often recommending a switch from antiplatelet therapy to oral anticoagulants for secondary prevention.Areas covered: Cardiac implantable electronic devices (CIED) with their long-term recording capability allows to document AF and to quantify the arrhythmia burden. Recent series in pacemaker and implantable cardioverter-defibrillator (ICD) recipients with no prior stroke showed that short episodes of AF increased stroke risk compared with those without AF recorded. Detection of AF by CIEDs represent a unique opportunity for promp prevention of embolic risk in silent AF. It will be attractive to identify AF before a stroke occurs.Expert commentary: The purpose of this article is to review the role of CIED to detect AF, to quantify the role of AF burden, and to guide primary and secondary stroke prevention
Silence is golden: an uncommon case of vocalization-triggered atrial tachycardia
No full textVocalization-related atrial tachyarrhythmias are extremely rare. We describe the case of a young woman in whom speaking was proven to be the trigger of a nearly incessant right atrial tachycardia, poorly controlled with medical therapy and successfully treated with catheter ablation. The identification of the trigger was pivotal for mapping and ablation, providing a reliable means to assess the success of the procedure
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
