Temporary artificial pacing after open-heart surgery (author's transl)
No full textA three-year experiences with the treatment by artificial pacing of the cardiac rhythm anomalies after open-heart surgery, at the Institute of Surgery of the Heart and Great Vessels, Ist School of Medicine, University of Naples, are reported. The most frequent arrhythmias occurring during or soon after open-heart surgery and the main aetiologic factors are examined. The surgical techniques for pacing and their indications are considered. Thereafter some particularly interesting cases are reported

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
