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.

Unusual Results
According to the range rule of thumb, any value above or below two standard deviations, 2σ from the mean, μ is considered unusual.

z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...
