Recipient P wave synchronized pacing of the donor atrium in a heart-transplanted patient: a case study.
We present the case of a 23-year-old patient who underwent orthotopic heart implantation and subsequent implantation of an atrial dual chamber pacemaker. The stimulation rate in the donor atrium is controlled by the recipient's sinus node activity, thereby maintaining AV synchrony and allowing appropriate rate increase during exercise.
