No full textRight Ventricular Tachycardia in Hypertrophic Cardiomyopathy. The case of a 57-year-old woman with a longstanding history of obstructive hypertrophic cardiomyopathy in dilatative phase and incessant monomorphic ventricular tachycardia is reported. Endocardial recordings and electroanatomic mapping suggested local reentry involving right ventricular apical septum, close to a pacing/defibrillation lead tip. Radiofrequency pulses delivered at this site resulted in definite cure of the arrhythmia. It is possible that fibrotic reaction around pacing/defibrillation lead in a diseased myocardium substrate has contributed to the creation of a reentry circuit. © 2007 by Futura Publishing Company, Inc
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
