Brugada syndrome phenotype cardiac arrest in a young patient unmasked during the acute phase of amiodarone infusion: disclosure and aggravation of Brugada electrocardiographic pattern.

abstract：BACKGROUND:While J-waves were observed in healthy populations, variations in their reported incidence may be partly explicable by the ECG filter setting. METHODS:We obtained resting 12-lead ECG recordings in 665 consecutive patients and enrolled 112 (56 men, 56 women, mean age 59.3±16.1years) who manifested J-waves on...
