Benign Prognosis of Early Sinus Node Dysfunction After Orthotopic Cardiac Transplantation

167 patients after orthotopic cardiac transplantation, including 120 with normal sinus node function (corrected SN recovery time < 520 ms) and 47 with impaired sinus node function (corrected SN recovery time > 520 ms and/or sinus arrest +/- escape rhythms).

Permanent pacemaker placement (performed in 24 patients with symptomatic bradycardia or absence of sinus rhythm at discharge).

Observation without specific therapy (in 23 patients with asymptomatic sinus node bradycardia) and patients with normal sinus node function.

Overall and cardiac mortality at a mean follow-up of 46.7 months.hard clinical
