The Association of Atrial Tachyarrhythmias with Isolated Atrial Amyloid Disease: Preliminary Observations in Autopsied Heart Specimens

Abstract

In a collaborative, preliminary, pilot assessment of autopsied hearts for which premortem ECGs were necessarily screened retrospectively, significantly more hearts with high-grade IAA were associated with atrial tachyarrhythmias compared to those with low-grade IAA. A larger study with an appropriately matched autopsy control group is needed to confirm these and previous observations.
