Chest Pressure at 07:05 in a Clinic With No Physician On Site
At 07:05 on a Tuesday you are the only clinical staff member in a three-room outpatient cardiology satellite office. The receptionist is at the front desk; the first physician is not scheduled until 08:00. A 58-year-old man walks in without an appointment reporting 40 minutes of 'pressure like a belt tightening' across his chest, radiating to his left jaw, with nausea and sweating. He is alert, pale, and diaphoretic. Blood pressure 148/92, heart rate 104, respirations 22, SpO2 95% on room air. You record a 12-lead ECG at standard settings. Leads II, III, and aVF show 3 mm of ST elevation with reciprocal depression in aVL; leads V1 through V3 show no ST elevation. The patient asks, 'Am I having a heart attack? My wife has nitroglycerin in the car, should I take one?' He then says he would rather drive himself to the hospital 'so I don't make a fuss.' The receptionist asks you to 'just tell him what the strip says' so the morning schedule does not back up.
1. List, in order, the next five actions you take in the first ten minutes, and state for each whether it falls inside or outside the ECG technician's scope.

Keep him in the exam room, seated or reclining, and stay with him. Sending him back to the waiting room or letting him walk to the parking lot abandons an unstable patient. Duty of care and continuous observation are inside your role; deciding he is stable is not.
Activate emergency medical services (911) or the facility emergency response system immediately. Recognizing a life-threatening pattern and pulling the pre-defined emergency handle is a technical and administrative act, not a diagnosis. Note the exact time of the call.
Notify the covering physician or on-call provider by telephone while EMS is en route, using objective language: '3 mm ST elevation in II, III, and aVF with reciprocal change in aVL in a man with 40 minutes of chest pressure.' Describing the tracing is inside scope. Announcing 'he is having an inferior MI' as your own conclusion is outside it, because interpretation and diagnosis belong to the licensed provider.
Repeat vital signs and, only if your facility protocol authorizes it, a repeat tracing (for example right-sided or posterior leads per protocol). Do not delay EMS transport to obtain additional leads, and retain the original strip exactly as printed.
Administer nothing - no nitroglycerin, no aspirin, no oxygen beyond what a licensed provider orders under protocol. Medication administration and treatment decisions are outside scope.
The dividing line: recognize, record, escalate, and document are yours. Interpret for treatment, prescribe, or clear the patient to travel are not.
2. How do you respond to (a) the heart attack question, (b) the request for his wife's nitroglycerin, (c) his plan to drive himself, and (d) the receptionist's request?
Read the worked answer
- (a) Heart attack question. Be calm, honest, and non-diagnostic: 'Your ECG shows a change that needs emergency evaluation right now. I am not the person who interprets it, but I have already called 911 and spoken with the doctor.' Avoid both 'No, you are fine' and a definitive diagnosis. False reassurance delays care; a technician's diagnosis oversteps scope and can be wrong.
- (b) Nitroglycerin. 'I can't advise you to take someone else's prescription, and I can't give you medication. The paramedics will assess you and can treat you safely.' Taking another person's drug is unsafe: unknown dose and age, unknown contraindications (for example recent phosphodiesterase-5 inhibitor use or right ventricular involvement), and no order exists for it.
- (c) Driving himself. Do not facilitate it. Explain that an ambulance allows monitoring and treatment en route. If he insists and tries to leave, do not physically block him; state the risk plainly, notify the provider, document his exact words and the advice given, and let EMS and the provider manage the refusal. An informed refusal is a documented event, not a technician's permission slip.
- (d) Receptionist. 'I can't give him results - I've escalated to the physician and EMS is coming.' Releasing an interpretation to a non-clinician, or to the patient as a substitute for provider communication, breaches privacy norms and scope.
3. What do you document, and how do you hand off to EMS?
Read the worked answer
Document in time-stamped, objective terms:
- 07:05 arrival, chief complaint in the patient's own words, vital signs, appearance.
- 07:12 12-lead acquired; paper speed 25 mm/s, gain 10 mm/mV, standard placement, your initials.
- 07:14 tracing described factually to Dr. ___ by phone, with read-back of the description.
- 07:15 EMS activated, time of call, estimated arrival.
- Patient statements about nitroglycerin and driving, and the advice given in response.
- The original strip retained in the record; no annotations that state a diagnosis.
Hand off using SBAR. Situation: 58-year-old man, 40 minutes of chest pressure with radiation, nausea, and diaphoresis. Background: walk-in, no appointment, BP 148/92, HR 104, SpO2 95%. Assessment: as reported, not as diagnosed - 'the ECG shows ST elevation in the inferior leads; the physician has been notified.' Recommendation: transport with monitoring; the receiving physician is aware.
Two documentation traps to avoid: writing a diagnosis in your own note, and discarding or 'correcting' the first tracing. If anything, obtain and keep a second one.
