Clinical limitations
- Coronary dominance and branch anatomy vary. ECG and echo suggest a territory; neither identifies a culprit artery with certainty.
- A normal focused echo does not exclude acute coronary occlusion. Poor windows and subtle or early changes limit sensitivity.
- Regional dysfunction may also reflect old infarction or a non-ischaemic cause. Interpret it with symptoms, serial ECGs and the clinical context.
- Echo should not delay indicated reperfusion. New shock or a murmur warrants urgent assessment for mechanical complications.
Educational simulations, not patient recordings. ECG and echo suggest a territory; neither proves an acute occlusion. A normal focused echo does not exclude it. Echo must not delay indicated reperfusion. New shock or a murmur requires urgent assessment.
