Contemporary atrial pacemakers incorporate pacing modes for treating atrial arrhythmias. Because atrial fibrillation in the right atrium can exhibit an organized pattern, it can be difficult to differentiate from atrial flutter. We assessed criteria for discriminating between atrial flutter and organized atrial fibrillation when using a bipolar electrode in the right atrium. ⋯ Cycle length was better than the variation in cycle length for differentiating atrial flutter from organized atrial fibrillation.

The aim of this study was to analyze the patterns of investigator and institutional collaboration in papers published in the Revista Española de Cardiología. ⋯ An analysis of collaboration networks led to the identification of a number of author networks in cardiovascular medicine in Spain, and highlighted the interrelationships between them in terms of both scientific research and scientific publications. The most significant aspect of institutional collaboration was the predominance of collaboration within institutions and within Spanish autonomous regions (i.e., 80.57% of collaborations). Possible topics for future study include an analysis of the scientific productivity of the networks identified and of changes in the pattern of collaboration over time.
