| pubmed-article:669108 | pubmed:abstractText | We have studied 20 cases Wenckebach A-V block by atrial pacing. The relationships between conduction time and recovery time of N. AV Wenckebach point, basal A-H time and A-H time of first cycle beat were analysed. No correlation was found between W point, basal A-H and A-H of the first beat by analysing the A-H = f (H-A) we found different curves which occur when the first A-H is longer or shorter than 110. These data were discussed on the basis of modern hypotheses of electrophysiological mechanism of Wenckebach periodism. | lld:pubmed |
