title: Unusual atrial potentials in a cardiac transplant recipient. Possible synchronization between donor and recipient atria.
abstract: It is usual to record independent activity from both the innervated recipient and the denervated donor atria in cardiac transplant recipients except for occasional, short-lived periods of entrainment that may occur during exercise. In this report a case is described in which, following orthotopic cardiac transplantation, the recipient and donor atria remained synchronized during a variety of physiological and non-physiological situations. Under no circumstances did the two sets of atria beat independently. The mechanisms that might be involved in this unique situation are discussed.
