Chest Pain in the Waiting Room: Who Do You Take First?
You are the only EKG technician on duty at 07:40 in a 12-lead outpatient clinic. Three patients are waiting. Patient A, 58, walked in with 20 minutes of crushing substernal pressure radiating to the left jaw, is diaphoretic and pale, and rates pain 8/10. Patient B, 71, has a scheduled pre-op EKG at 08:00 and reports palpitations that started last night; she is alert, pink, and speaking in full sentences. Patient C, 34, needs a routine EKG for a new job physical and is annoyed about waiting. The clinic has one EKG machine and one exam room. The receptionist asks you to "just do them in the order they signed in," and Patient A's wife is asking why he hasn't been seen.
1. How should you sequence these patients, and what is the reasoning behind your order?

Triage by acuity, not arrival order.
- Patient A first, immediately. Crushing substernal pressure radiating to the jaw with diaphoresis is a classic acute coronary syndrome presentation. This is a time-critical emergency; the EKG is diagnostic and must not wait.
- Notify the provider/clinic emergency protocol now, not after the tracing. Do not leave him alone in a waiting room.
- Patient B second - palpitations are concerning but she is hemodynamically stable and conversational; a short delay is acceptable.
- Patient C last - routine, non-urgent.
Key judgement: the receptionist's sign-in order is administrative, not clinical. Your obligation is to escalate a suspected ACS rather than to preserve queue fairness. Tell the wife plainly that her husband is being taken back right now because of his symptoms.
2. Patient A's 12-lead shows 2 mm of ST elevation in leads II, III, and aVF. What do you do with this information, and what are your limits as an EKG technician?

Action: Treat it as an emergency finding. Do not interpret it for the patient or reassure him. Immediately hand the tracing to the provider (or activate the clinic's emergency response per policy), state the objective facts - "ST elevation in II, III, aVF, patient with 20 minutes of chest pain and diaphoresis" - and stay with the patient while help arrives.
Limits of your role: You may recognize a pattern and escalate; you do not diagnose, do not tell the patient he is "having a heart attack," and do not advise treatment. You also do not delay escalation to obtain a "better" tracing.
Practical detail: Keep the original tracing labeled with patient name, time, and lead placement; a repeat 12-lead may be requested, and serial tracings are compared.
3. Patient A's wife asks, "Is he having a heart attack?" What is an appropriate response, and why?
Read the worked answer
Acknowledge, do not diagnose. Something like: "I understand this is frightening. His symptoms and his heart tracing are concerning, so the doctor is seeing him right now. I'm not able to interpret the results for you - that's the doctor's job - but I'll stay with you and make sure you know what's happening."
Why: Scope of practice. Telling a family member "yes, he's having a heart attack" is a diagnosis you are not licensed to deliver, and "no, it's probably nothing" is worse - it could cause delay if they decline care. Your job is to be honest that something is being taken seriously, keep them informed of process, and route clinical questions to the provider.
