Which telemetry finding should prompt prompt clinician notification in a patient with ACS risk factors?

Which telemetry finding should prompt prompt clinician notification in a patient with ACS risk factors?

• A. Absence of changes on telemetry
• B. New ST-segment elevation or depression
• C. Normal rhythm
• D. No symptoms

Answer: (B)

The key idea is that new ST-segment elevation or depression on the ECG during ACS risk factors signals acute myocardial ischemia or injury. ST elevations suggest a transmural infarction, while ST depressions reflect subendocardial ischemia; both require immediate clinical escalation—activate the ACS protocol, consider emergent reperfusion if indicated, and promptly assess troponin and hemodynamics. In contrast, absence of changes, a normal rhythm, or no symptoms do not indicate an ischemic emergency, so they do not prompt the same urgent clinician notification.
