Riccardo Muti‘s recent fainting spell that resulted in surgery for a broken jaw was caused by a” heart rhythm disturbance,” say his doctors. The conductor has been fitted with a pacemaker to regulate his heart rate, and is expected to make a full recovery.

In a statement released by the Chicago Symphony Orchestra Association, Muti said, “I think it was destiny that I came to Chicago and I think what has happened is also destiny, because now I understand and feel more comfortable than ever about returning to my work.”
