Ma. Salim et al., The wandering pacemaker: Intraperitoneal migration of an epicardially placed pacemaker and femoral nerve stimulation, PEDIAT CARD, 20(2), 1999, pp. 164-166
A premature child with congenital complete heart block had an epicardial si
ngle-chamber pacemaker implanted at 2 days of age. At 21 months of age, whi
le sitting or standing, the patient's right anterior thigh muscles contract
ed at her pulse rate. Surgical exploration revealed a free-floating pacemak
er in her peritoneum. A new dual-chamber pacemaker was implanted into the a
bdominal wall with resolution of the child's symptoms.
