  • Title: When two hearts do not beat as one - An unusual cause of pacemaker related tachycardia.
    Author: Zormpas C, Mueller-Leisse J, Duncker D, Veltmann C.
    Journal: J Electrocardiol; 2019; 57():6-9. PubMed ID: 31442564.
    Abstract:
    We describe an unusual cause of intermittent rapid ventricular paced rhythm in a patient implanted with a dual chamber pacemaker due to sinus node dysfunction after heart transplantation. During implantation of the pacemaker lead measurements were reported normal, atrial sensing was not documented because of sinus arrest. After implantation the patient complained about intermittent palpitations. Via pacemaker interrogation we could demonstrate electrical isolation of the atrial lead, which was implanted in the donor's atrial myocardium. This led to intermittent pacemaker related tachycardia and AV-dissociation. This case report highlights the difficulty of atrial lead placement in heart transplanted patients using the biatrial surgical technique.
