Present in 2-5% of the population, mainly males, young adults, and
athletes. Possibly related to high cardiac sympathetic – can normalise with exercise or Beta-Blockade.
*** Generally disappears in middle age, rare in the elderly.
*** Elevated J Point, often with notching. Predominantly in anterior chest leads, but can occur elsewhere.
*** Elevated J Point in Inferior leads more arrhythmogenic.
*** I had been considered as benign ECG change, till a couple of studies published in 2008 Evaluated the clinical association between early my presence in the inferolateral leads and idiopathic ventricular arrhythmias leading to syncope and/or sudden cardiac death.
*** To differentiate me from Pericarditis : both are associated with concave ST elevation: look at the ST segment / T wave ratio in V6:
A ratio of > 0.25 suggests pericarditis
A ratio of < 0.25 suggests Me.
So…Who Iam i??
