Paroxysmal atrial fibrillation (PAF) reduces atrial contractility due to atrial remodeling, but little is known about the process by which contractile function is reconstituted after spontaneous conversion to sinus rhythm (SR). A 63-year-old healthy man developed PAF. PAF persisted for 2 days before spontaneous conversion to SR. Serial echocardiograms were performed at 1, 24 h, 3/4/7 days after conversion. Longitudinal myocardial strain during the pump phase of the left atrium (LA) was generally reduced at 1 h. Normal str
