The remarkable feature is the poor [[R wave]] progression in the [[Electrocardiogram#Precordial|V1]] and [[Electrocardiogram#Precordial|V2]] leads and the [[ST elevation]] and T wave changes in leads [[Electrocardiogram#Precordial|V1]] to [[Electrocardiogram#Precordial|V4]] and [[Electrocardiogram#Limb|I]] and [[Electrocardiogram#Augmented limb|aVL]]. The cardiogram suggests an anterior/ lateral MI possibly acute. There is also terminal P wave negativity in [[Electrocardiogram#Precordial|V1]] suggesting a left atrial abnormality.
