Webhow a J deflection can be inscribed on an S wave which is essentially a negative deflection, i.e. a wave below the level of QRS onset. A more recent paper by Tikkanen et al [9] has suggested that the ST slope is of more importance than STj amplitude. On the other hand, they gave an example where there was no ST junction elevation whatsoever but http://www.theweatherprediction.com/habyhints/111/
