Myocardial perforation by flexible Elema endocardial pacing catheters.

Long-term epicardial ventricular pacing from endocardial bipolar pacemaker lead: perforation of right atrial wall.

One of the hazards of endocardial cardiac pacing is that the pacemaker lead may perforate the myocardial wall or interventricular septum although the incidence of such perforations is believed to be small. This paper describes what is believed to be a unique case in which a pacemaker lead perforated the atrial wall at implantation (or possibly shortly afterwards) and yet gave satisfactory right...

Successful treatment of myocardial perforation and tamponade after temporary endocardial pacing.

Robotic positioning of standard electrophysiology catheters: a novel approach to catheter robotics.

BACKGROUND Robotic systems have been developed to manipulate and position electrophysiology (EP) catheters remotely. One limitation of existing systems is their requirement for specialized catheters or sheaths. We evaluated a system (Catheter Robotics Remote Catheter Manipulation System [RCMS], Catheter Robotics, Inc., Budd Lake, New Jersey) that manipulates conventional EP catheters placed thr...

Long-term follow up of cardiac pacing threshold using a noninvasive method of measurement.

Seventeen patients were followed up for a period ranging from 12 to 40 months after implantation of an Elema Vario pacemaker with an endocardial electrode. Two patients had a greater stimulation threshold beyond 6 months after implantation than the maximum threshold recorded before 6 months. One of these patients required replacement of the pacing system because of exit block. The 16 patients w...

Intracardiac pacing as emergency treatment in Adams-Stokes syndrome.

In most cases of atrioventricular block with Adams-Stokes attacks the application of either an endocardial or an epicardial electrode for artificial pacing can be performed in the operating-theatre with all necessary equipment available. In some cases, however, the situation is more dramatic: electrical pacing may be necessary without any delay, and it may be impossible to transfer the patient ...
