Hyperkalaemia is associated … SpletThis has been described as a normal variant in healthy individuals ( 1) in whom STj is very often elevated. The term “early repolarization” has been used to describe the latter phenomenon with or without end QRS notching or slurring ( 2 ). Until recently, end QRS notching or slurring has generally been considered benign.
