In continuation to this ECG Presentation

• I have uploaded two more topics on ECG namely AV Nodal Blocks & Posterior wall infarction the link is given as below

Myocardial Infarction

• The ST segment should start isoelectric except in V1 and V2 where it may be elevated

Three Phases of Myocardial infarction

• The Hyper-acute Phase• The Fully Evolved Phase• The Chronic Stabilized Phase

EXAMPLES //MYOCARDIAL INFARACTIONTRY TO READ AND INTERPRET

Elevation of the ST segment (greater than 1 small box) in 2 leads is consistent with a myocardial infarction.

Do you think this person is having a myocardial infarction. If so, where?

Interpretation

Yes, this person is having a Septal wall myocardial infarction.

EXAMPLES //MYOCARDIAL INFARACTIONTRY TO READ AND INTERPRET

Elevation of the ST segment (greater than 1 small box) in 2 leads is consistent with a myocardial infarction.
