A patient with dilated cardiomyopathy and DDD pacemaker experienced paroxysmal returns of her symptoms. IEGM revealed VA cross-talk resulting in functional undersensing of the following P wave that occurred during the PVARP and initiating a pacemaker syndrome with the pacemaker as a bystander.

A 57-year-old female was implanted with a Biotronik Pikos VVI pulse generator. During her follow-up period right bundle-branch block was observed. Therefore further posteroanterior and lateral chest X-ray and echocardiography were performed. Only the transoesophageal echocardiography showed exactly the abnormal pathway of the electrode through the foramen ovale apertum to the left side of the heart. Abnormal electrode position can create serious complications, however, our patient remained free of symptoms throughout her 5 year follow-up.
We report a case of lead migration into the right middle pulmonary lobe. The migrated electrode reached the pleura and produced severe pleural symptoms, therefore, surgical removal of the retained lead was required. This case report demonstrates the importance of a chest X ray in the follow-up of patients with an implanted pacemaker to detect complications like lead fracture or migration.
