ECG in acute coronary syndrome Patients presenting acutely unwell secondary to compromised myocardial blood supply are said to be suffering from an acute coronary syndrome (ACS). Based on clinical findings, ECG abnormalities and blood test analysis, acute coronary syndromes can be divided into three categories: - ST elevation MI (STEMI) correlates with complete vessel occlusion and NonST-elevation MI (NSTEMI) correlate with partial vessel occlusion Unstable angina (UA) Stemi sequence of ECG changes When an atheromatous plaque ruptures in a coronary vessel, and the clot which forms completely obliterates the vascular lumen, the entire thickness of the myocardial wall supplied by that vessel becomes ischemic and is at risk of infarction.
These events produce a series of changes on the ECG in the leads overlying the area of myocardium at risk of death. Stemi ECG changes: Variable and…
