Background
Premature ventricular contraction (PVC) is a frequent kind of arrhythmia
that affects around %1 of the general population. While PVC most
frequently impairs ventricular function in structurally normal heart,
retrograde ventriculo-atrial conduction can occur in people with PVC.
These retrograde atrial activations may mimic pulmonary vein-derived
atrial ectopies. As a result, PVC may raise the risk of AF by retrograde
ventriculo-atrial conduction.
The Four-Dimensional Automated Left Atrial Quantification (4D Auto LAQ)
tool is a left atrial analytical approach that utilizes
three-dimensional volume data to quantify the volume, as well as LA
longitudinal and circumferential strains. The purpose of this study was
to determine if clinical diagnosis of PVC is connected with abnormal LA
function as determined by LA strain evaluation utilizing a 4D Auto LAQ
compared to the healthy population.
