Bloqueo auriculoventricular paroxístico desencadenado por estímulo vagal con síncope recurrente
Abstract
Paroxysmal complete atrioventricular block (CAVB) with normal electrocardiogram at rest is uncommon. A34 year-old two month pregnant woman consulted for recurrent syncope. After screening assessment with electrocardiogram, cardiac echo-Doppler, tilt test, electro- encephalogram, brain computerized tomography and magnetic resonance imaging, cardio- pathy was ruled out and a diagnosis of neurocardiogenic syncope was made. As symptoms persisted, a5 day-Holter monitoring was performed until she presented a new episode of syncope and paroxysmal CAVB was diagnosed. Adefinite VDD pacemaker was implanted and six months later she remained free of symptoms.
