Multiple external pacing electrode summation in dogs

Unusual fracture of cardiac pacing electrode.

This report describes a patient with an epicardial demand pacing system in whom pacing failure two months after implantation was found to be due to a fracture of the helical wire electrode within its supporting structure. We know of no report of this site of failure of a Cordis 323-451 or similar electrode.

Extraluminal insertion of a pacing electrode.

Prolonged temporary cardiac pacing using an external permanent pacing system.

The number of pacemakers and implantable cardioverter defibrillators implanted each year continues to grow in Spain, due largely to the increased life expectancy of the population in the case of pacemakers and the indications for primary prevention in the case of implantable cardioverter defibrillators. Although the incidence of infections associated with implantable cardiac devices is not high...

A Virtual Electrode through Summation of Time Offset Pulses

Retinal prostheses have been successful in eliciting visual responses in implanted subjects. As these prostheses progress, one of their major limitations is the need for increased resolution. As an alternative to increasing the number of electrodes, virtual electrodes may be used to increase the effective resolution of current electrode arrays. This paper presents a virtual electrode technique ...

Re-usage of external pacing electrodes results in skin burns.

A 29 year old woman with a background of poorly controlled iabetes was admitted to our hospital in cardiogenic shock due o acute inferior myocardial infarction and complete heart block. ecycled external electrodes (“stat.padz®”) were placed to the right f the upper sternal border below the clavicle and to the left of he nipple with the centre of the electrode in the mid-axillary line. xternal p...
