Cardiodesfibriladores implantables: ¿se puede predecir un umbral desfibrilatorio elevado antes del implante? / Implanted cardiodefibrillator: can be predictible and elevated defibrillation threshold testing previous to the implantation?

Implanted cardiodefibrillators devices are being used with increasing frequency to provide primary and secondary prevention of arrhythmic sudden death. Between March 2003 through Febraury 2005, 99 consecutive patients were included in a study to test the defibrillation threshold at the time of an implantable cardiofibrillator insertion. The systematic measurement of defribillation threshold during the insertions of an implanted defibrillator, still is a necessary resource in order to identify patients in whom the margins of standard security could not guarantee a successful defibrillation. The possibility to identify elevated defibrillation threshold testing is very important to be determined at the time of indications for the insertion of an implanted cardiodefibrillator. These consideations are discussed in the article
