The use of fibrillation cycle length to determine spatial dispersion in electrophysiological properties and to characterize the underlying mechanism of fibrillation.

Note: This was a short paper that was published in 1986 in a now defunct journal that covered the proceedings of a conference held in Marilleva, Italy (Jan 25-Feb 1, 1986) by Professor Furlanello and his colleagues. Apparently, to my great surprise, this paper has been cited many times. However, as the text is not available on the internet (New Trends in Arrhythmias never made it to the PubMed heaven), I scanned the original paper which you can download. Thanks to Toban Dvoretzki (manuscript editor with the Texas Heart Institute Journal (Houston, Texas, USA ) for the tip! download
