How does left atrial function, measured by atrial strain rate, change after cardioversion from chronic atrial fibrillation?
Atrial strain rate imaging can detect the transient reduction and subsequent recovery of left atrial function following cardioversion for chronic atrial fibrillation.
A-sr is a descriptor of atrial function, which is reduced after cardioversion from CAF and subsequently recovers.
Thomas et al. (2006) studied this question.
