RESUMEN
El síndrome de aurícula paralítica es una entidad poco común y generalmente se presenta aislada o asociada a trastornos degenerativos musculares. Se ha propuesto un mecanismo de transmisión familiar por transmisión autosómica dominante. Su presentación es más frecuente en hombres jóvenes y puede manifestarse como evento cerebrovascular, falla cardiaca o fenómenos tromboembólicos. En este artículo se presenta el caso de un hombre joven con historia de síncope recurrente y quien había recibido, tiempo atrás, implante de marcapaso definitivo monocameral. Se descartaron enfermedades inflamatorias cardiacas, distrofias musculares y otras causas secundarias de su trastorno en la formación del impulso sinusal. Una vez la batería de su marcapaso se encontró cerca de su fin de vida y durante el cambio programado del generador, se realizó estudio electrofisiológico de la aurícula y no se encontró mayor actividad...
ABSTRACT
Atrial palsy syndrome is an uncommon entity which generally occurs isolated or associated with degenerative muscular disorders. An autosomic dominant familiar transmission mechanism has been proposed. It appears more frequently in young males, and may be manifested as cerebro-vascular event, heart failure or thromboembolic phenomena. In this article, the case of a young man with history of recurrent syncope, who had received in the past a definitive single chamber pacemaker implant, is presented. Inflammatory heart diseases, muscular dystrophies and other secondary causes of his sinus impulse disorder were ruled out. An atrial electrophysiological study during the programmed change of the generator was performed, just before one of the pacemakers batteries began to discharge. No mayor activity was found. An atrial electrode was implanted and echocardiographic follow-up of the auricular function was performed, showing a discrete improvement six months after the implant and then returning to the basal values, reason by which the atrial channel was turned off. Although some patients regain atrial function after cardioversion for atrial fibrillation, the percentage of patients that could do it after atrial stimulation in a little mechanically and electrically active auricle, is unknown. Therefore, the measurement of atrial activity and the stimulation before deciding the implant of an atrial electrode are very useful.
