Conditions with tall and peak T wave (Incomplete)
. Acute myocardial infarction
(In hyperacute T wave stage)
Distinct J point
ST elevation in acute MI has variable characistic and magnitude.
Continue to change, (evolving patterns).
1a = Tall and peak T
1b = Narrow T
1c = Slur J point
No ST elevation
(There are other P, QRS, and ST T abnormalities in hyperkalemia)
ST elevation Yes Yes No Type of ST Concave Concave in very early hyperacute peak T wave.
Convex in later stage.
Concave QT interval Normal Normal in hyperacute peak T.
Tend to be prolonged in later stage)
Narrow T wave J point Distinct May be slurred Slur Location More frequent in precordial leads Depending on location of MI. More prominent in anterior MI. More global but more evident in precordial leads Reciprocal change No Yes in early stage .In leads opposite MI location. No See more detail from each specific diagnosis
