This observation highlights that atrial stunning following cardioversion can occur asymmetrically, affecting the left but not the right atrium.
The presence of a normal atrial electrical activity together with the absence of mechanical atrial activity has been reported after successful cardioversion and is named atrial stunning. In this observation, we report the existence of left but not right atrial stunning.

Meune et al. (2020) conducted a case report in Persistent atrial fibrillation (n=1). Electrical cardioversion was evaluated on Atrial mechanical activity. In a 70-year-old man with persistent atrial fibrillation, successful electrical cardioversion resulted in left but not right atrial mechanical stunning despite normal sinus rhythm.
