[Incidence and outcome of fascicular blocks in the aged. Retrospective studies]. / Frequenza ed evoluzione dei blocchi fascicolari negli anziani. Indagine retrospettiva

ABSTRACT

The results of a three-year follow-up study of 45 elderly subjects (mean age 79,5 years, range 67-96 years) with left anterior hemiblock (LAH) alone or associated to right bundle branch block (RBBB) are reported. In the presence of isolated LAH no significant changes in the mortality rate were observed. The patients with LAH+RBBB showed an increase in mortality rate and not rarely (2 cases out of 13) an evolution toward a complete A-V block. The role of age as a factor influencing the natural history of these patients is discussed.
