[Prolonged asystole requiring resuscitation techniques during head-tilt table test].
We describe a case of a patient with recurrent syncope without cardiac disease and with a normal electrophysiological study. The patient underwent a head-up tilt table test as a diagnostic method. During the test the individual suffered a twenty-nine seconds cardiac asystole. He recovered the cardiac rhythm nineteen seconds after having adopted the supine position and with resuscitation maneuvers. In the consulted bibliography, there is no evidence of such a long asystole induced during a head-up tilt table test, where the patient required a chest thumping. Commonly the spontaneous recuperation of the cardiac rhythm takes place immediately after the patient adopts a horizontal position. This case supports the hypothesis that the asystole provoked by a cardioinhibitor reflex in patients suffering from a vasovagal syncope, can become potentially lethal and therefore lead to sudden cardiac death.
