Case 334 Medical history A 21-year-old previously healthy male patient was admitted to the emergency department due to the sudden onset of palpitations, dyspnea and dipahoresis. Paroxysmal supraventricular tachycardia was diagnosed, a 6 mg adenosine bolus was administered and the patient developed ventricular fibrillation and cardiac arrest. Return of spontaneous circulation was achieved after the first cardiopulmonary resuscitation cycle and a 12-lead electrocardiogram was obtained (images 1, 2 and 3). 12-lead electrocardiogram, peripheral leads.12-lead electrocardiogram, leads V1 to V3.12-lead electrocardiogram, leads V4 to V6. Question:Based on the 12-lead electrocardiogram and the clinical scenario, what is the most likely diagnosis? Wolff-Parkinson-White syndrome. Brugada syndrome. Stokes-Adams syndrome. Lown-Ganong-Levine syndrome. Questão de Prova Votorantin Municipality – Cardiologist (2010)Question:Concerning the Wolff-Parkinson-White syndrome, which of the following CANNOT be stated? Due to the risk of sudden death, electrophysiological studies should be performed in all patients, even those who are asymptomatic. It may be associated with sudden death in some patients. The most frequent arrhythmia in patients with this syndrome is paroxysmal supraventricular tachycardia through an abnormal pathway. The abnormal pathway responsible for the syndrome is the Kent bundle. Time is Up! Time's up
