A younger patient with concerning chest symptoms has ST elevation resembling early repolarization, and an older ECG shows a similar stable pattern. Which interpretation is most appropriate?

A
A stable early-repolarization pattern on a prior ECG excludes new acute coronary syndrome.
B
A stable early-repolarization pattern may help distinguish the tracing, but concerning symptoms still warrant evaluation.
C
Early repolarization is confirmed whenever ST elevation is present.
D
A prior ECG should not be compared with the current tracing.

A patient is pain-free after chest discomfort, but the ECG shows deep, symmetric T-wave inversion in V2–V3. What is the most appropriate next step?

A
Arrange exercise stress testing to determine whether the changes are significant.
B
Dismiss the finding because the patient is currently pain-free.
C
Avoid exercise stress testing and seek urgent specialist assessment.
D
Conclude that the pattern excludes critical coronary disease.

Which statements accurately describe features that may help distinguish common STEMI mimics? Select all correct answers.

A
Early repolarization is often stable on prior ECGs.
B
Acute pericarditis often has widespread, relatively concave ST elevation with PR depression.
C
Brugada pattern typically involves characteristic right-precordial ST elevation in V1–V3.
D
Takotsubo syndrome can be reliably distinguished from coronary occlusion by ECG alone.

For a patient with suspected NSTE-ACS and no persistent ST elevation, which management principles are appropriate? Select all correct answers.

A
Use serial ECGs and cardiac troponin testing with clinical risk assessment.
B
Arrange urgent specialist evaluation for dynamic ischemic changes, confirmed MI, or instability, with an invasive strategy guided by risk and local protocols.
C
Use one nondiagnostic ECG to rule out NSTE-ACS.
D
Wait for a troponin result before acting on any concerning clinical or ECG findings.

A patient has persistent ischemic symptoms and is becoming unstable, but the standard 12-lead ECG is equivocal. Describe the immediate evaluation and escalation steps that are appropriate, including how to use repeat or additional ECG leads and whether troponin results should delay reperfusion-pathway action.

An ECG shows upsloping ST depression at the J point across the precordial leads with tall, symmetric T waves. Which interpretation best fits this pattern?

A
A benign normal variant that excludes acute coronary occlusion
B
A de Winter pattern that can indicate acute LAD occlusion
C
A finding that confirms pericarditis
D
A pattern that rules out the need for urgent expert assessment

True or false

1 point

A STEMI-pattern ECG can support an initial working diagnosis that triggers urgent reperfusion assessment, even though the patient may not ultimately have a confirmed infarction. True or false?

True
B
False

A patient with possible acute coronary syndrome has a nondiagnostic initial ECG, but chest discomfort continues. What is the most appropriate ECG-related next step?

A
Treat the first tracing as definitive and stop ECG assessment
B
Repeat ECGs, especially during persistent or recurrent symptoms, and consider additional leads
C
Wait for a troponin result before obtaining any further ECG
D
Use a stable prior ECG to rule out a new acute event

A patient with suspected acute coronary syndrome has ST depression in V1–V3. Which interpretation and follow-up best account for the possibility of posterior injury?

A
Conclude that the changes establish anterior ischemia and need no further assessment
B
Treat the pattern as a normal variant if the patient is pain-free
C
Consider posterior injury and obtain leads V7–V9 when suspicion persists
D
Use right-sided leads only, because they directly assess the posterior wall

A pain-free patient has deep, symmetric T-wave inversion in V2–V3 after a recent episode of chest pain. Which response is most appropriate?

A
Proceed with exercise stress testing to reproduce the symptoms
B
Dismiss the ECG finding because the patient is currently pain-free
C
Repeat the ECG only if pain returns, without further assessment
D
Recognize a possible Wellens pattern, avoid exercise stress testing, and seek urgent specialist assessment
