 '''Early repolarization''' is a term used for ST elevation without underlying disease. It probably has nothing to do with actual early repolarization. It is commonly seen in young men. It is important to discern early repolariztion from ST elevation from other causes such as [[ischemia]]. Characteristics of early repolarization are:<cite>Kambara</cite>
-*concave elevation of the ST segment with a clear J wave
+# an upward concave elevation of the RS-T segment with distinct or "embryonic" J waves
-*vertraagd einde van de R golf of een duidelijke J golf of beide
+# slurred downstroke of R waves or distinct J points or both
-*snelle QRS progressie in de voorwandsafleidingen met counterclockwise draaiing
+# RS-T segment elevation commonly encountered in the precordial leads and more distinct in these leads
-*symmetrische grote T golven
+# rapid QRS transition in the precordial leads with counterclockwise rotation
-*diffuse ST elevatie (niet in 1 stroomgebied, geen reciproke depressies)
+# persistence of these characteristics for many years
-*persisteren van deze afwijkingen over de jaren
+# absence of reciprocal ST depression
