Rohan reached a diagnosis but missed safety-critical signal — the errors below trace back to unpinned red flags and context.

Why these went wrong

Each error traced back to the pin decisions that caused it

Safety

Omitted Aortic dissection — a can't-miss diagnosis

BecauseNever pinned “Heart Rate” and “12-lead ECG and continuous telemetry with repeat saturations”, so nothing prompted the dangerous-alternative sweep for this presentation.

Heart Rate· Safety red flag12-lead ECG and continuous telemetry with repeat saturations· Safety red flag

Treat Aortic dissection as a must-exclude for this presentation — pin the context that makes it possible, then rule it in or out explicitly.
