[Extrasystole following heart transplantation].

A 43 year old man developed extensive supraventricular and ventricular extrasystoles (over 500 supraventricular extrasystoles per hour, VES class II) within 3 months after orthotopic heart transplantation because of dilatative cardiomyopathy. At the same time severe graft rejection (class III according to Billingham) was documented. After treatment of the rejection the following three controls by 24 hours Holter EKG showed only slight supraventricular extrasystoles of less than 10 per hour and in three consecutive myocardial biopsies no rejection process requiring additional treatment was found. In individual cases severe ventricular arrhythmia registered by the family doctor may be a first hint for early rejection. Since intervals for inpatient controls have been extended observation of extrasystoles may be helpful for initiation of a next inpatient control. Incidence of extrasystoles after heart transplantation in the cyclosporine-era is discussed.
