Endocardial electrograms from pacemaker catheters.
Proper placement of pacemaker catheters can be facilitated by recording endocardial electrograms from the catheters. These electrograms are also helpful in the investigation of pacemaker failure. Endocardial contact is indicated by S-T segment elevation. When bipolar catheters are used, these "contact currents" may be visible in electrograms from the tip or ring electrodes, or both. Right ventr...
متن کاملEndocardial Pacemaker Implantation in Neonates and Infants
Transvenous pacemaker lead implantation is the preferred method of pacing in adult patients. Lead performance and longevity are superior and the implantation approach can be performed under local anaesthetic with a very low morbidity. In children, and especially in neonates and infants, the epicardial route was traditionally chosen until the advent of smaller generators and lead implantation te...
متن کاملConstrictive pericarditis complicating an endocardial pacemaker.
SUMMARY A patient is described with constrictive pericarditis after insertion of an endocardial pacemaker. As far as we know this complication has not been reported previously. Permanent endocardial pacemakers are now commonly implanted and a number of complications have been described.1 Constrictive pericarditis has been reported as a complication of epicardial pacemakers2; this has never been...
متن کاملPulmonary embolisation of retained transvenous pacemaker electrode.
When removal of an endocardial pacemaker electrode became necessary in a patient with congestive myocardiopathy, it proved to be incarcerated. Therefore, a portion of it had to be left in site after cutting the external end of the pacing catheter. During follow-up examinations the electrode was seen to migrate in the large veins and finally was found embolized into a pulmonary artery. While the...
متن کاملEarly Malfunction of Transvenous Pacemaker Electrodes
A 3-year study by three medical centers has revealed a 1-year electrode malfunction rate of 7.4%; most malfunctions occurred within the first 30 days. The incidence of unavoidable early malfunction (3.2%) fell within the 5% standards suggested by the committee report of the Inter-Society Committee on Heart Diseases. Incidences of obscure cause (3.2%) may be difficult to identify prospectively a...
