Long or short QT syndrome and WPW syndrome can be denied in them. Of these, Brugada syndrome was established as a clinical entity since its report in 1992. The syndrome is characterized by peculiar ECG findings. In 1992 and 193, we also reported cases of IVF whose ECG displayed J wave, and the J wave amplitude was noted to be augmented at slower rate or after pauses. We have been collected 40 similar IVF patients since then, and in 2012, a half of the J-wave associated IVF patients were proven to show the bradycardia-dependent augmentation of the J-wave amplitude. Such subtle ECG changes can be a clue of IVF or can be a clue of malignant J waves and will be useful for risk stratification.}, pages = {1--13}, title = {最終講義 : 不整脈を巡って}, volume = {126}, year = {2012} }
