We report a 47 year old mate who was recuperated from a sudden death,
and in whom the cardiological assessment showed a right bundle branch
block and a fluctuating ST segment elevation from V1 to V3. During the
electrophysiological study, a polymorphic tachycardia and a ventricul
ar fibrillation were induced. Procainamide administration enhanced ST
segment alterations in right precordial leads, and isoproterenol norma
lized the EKG. All these disturbances are similar to the condition des
cribed by Brugada brothers. The patient was treated with an internal i
mplantable defibrillator, without the use of antiarrhythmic drugs and
is well after four months of follow up.
