Reperfusion Timing Brief: An Inferior STEMI at a Critical Access Hospital 70 Miles From a Cath Lab, First Medical Contact at 06:17, Tenecteplase at 07:09 and the Ten Minutes Nobody Logged

Seven Months Later

A.K. had declined anticoagulation and was followed in clinic. On a Sunday in October, A.K. woke at 05:40 with crushing chest pressure, nausea and sweating at a cabin in a rural county. A spouse called 911. The closest hospital, a critical access facility with 25 beds, has no cardiac catheterization laboratory; the nearest center able to perform primary percutaneous coronary intervention is 70 miles away by road.

The Declared Anchor

The anchor for the reperfusion intervals is first medical contact, the moment EMS reached A.K. at 06:17. The acute coronary syndrome guideline measures the goals for a patient first seen at a hospital without a catheterization laboratory from that contact: transfer for primary intervention when first medical contact to device is expected within 120 minutes, and fibrinolytic therapy within 30 minutes of hospital arrival when it is not and there are no contraindications (Rao et al., 2025).

What this page is doingDeclaring the anchor and the guideline intervals measured from it, before the table, tells the reader which subtraction the brief is about.

A Row for Every Event

Table 1

Event Timetable From First Medical Contact

Clock time	Minutes from first medical contact	Event	Information in hand
05:40	minus 37	Pain begins	None
06:05	minus 12	911 call	None
06:17	0	EMS at bedside	Symptoms, vital signs: BP 104/66, pulse 58
06:24	7	EMS 12-lead ECG	ST elevation in II, III, aVF; reciprocal depression in aVL
06:26	9	ECG transmitted to the hospital	Hospital physician sees STEMI
06:41	24	Arrival, critical access hospital (door)	EMS ECG
06:44	27	Repeat ECG	Same changes; right-sided leads show ST elevation in V4R
06:52	35	Call to PCI center	STEMI confirmed
06:52 to 07:02	35 to 45	No entry in the record	Unclear
07:02	45	Helicopter declined for weather; ground transfer estimated at 95 minutes	Direct transfer would bring device time well beyond 120 minutes
07:04	47	Fibrinolytic contraindication checklist completed	No contraindications; not taking an anticoagulant
07:09	52	Tenecteplase given, weight-based dose	Door-to-needle 28 minutes
07:35	78	Ground ambulance departs	Door-in-door-out 54 minutes
08:30	133	En route reassessment	Pain much reduced; ST elevation down by more than half
09:12	175	Arrival, PCI center	Signs of reperfusion
09:40	203	Coronary angiography begins	Right coronary artery lesion, partly open

Note. Note. Times from the EMS run sheet, the critical access hospital record and the PCI center record; one ten-minute stretch has no entry in any of them.

What this page is doingGiving every event a clock time and an interval from the anchor, including the empty stretch, makes the record auditable rather than narrative.

Arithmetic on the Page

First medical contact to fibrinolysis: 07:09 minus 06:17 is 52 minutes. Door to needle: 07:09 minus 06:41 is 28 minutes, inside the 30-minute goal. Door-in-door-out: 07:35 minus 06:41 is 54 minutes. Had A.K. been sent directly for primary intervention, departure at about 06:55 plus 95 minutes of road travel plus about 30 minutes from arrival to device would have given a first medical contact to device time near 160 minutes, well past 120. Fibrinolysis was therefore the right choice.

The Interval That Carries the Decision

The decision rested on the expected first medical contact to device time, not on the door-to-needle time. Door-to-needle shows how quickly the hospital acted once it chose fibrinolysis; the projected device time shows why it chose fibrinolysis at all. Once the helicopter was unavailable, the 120-minute goal could not be met.

The Stretch Nobody Explains

From 06:52 to 07:02 nothing is recorded. The call to the PCI center had confirmed the STEMI, and the ground transfer estimate came at 07:02 together with the helicopter answer. If those ten minutes were spent waiting for the flight service to reply, the delay could be removed in future by starting the fibrinolytic checklist in parallel with the flight request. Without an entry, the brief cannot say. It is recorded as a gap and referred to the hospital's quality review.

What this page is doingNaming the unexplained interval and proposing how it could be closed shows the brief is reading the record critically, not only summarizing it.

After Fibrinolysis

A.K. was transferred for routine angiography after fibrinolysis, which the guideline supports within 2 to 24 hours in stable patients, and urgently for failed reperfusion (Rao et al., 2025). Pain and ST elevation fell en route, signs of successful reperfusion, so angiography at 09:40 fell inside that window. European guidance sets the same 2 to 24 hour window for angiography after successful fibrinolysis (Byrne et al., 2023). The right coronary artery was partly open, and a stent was placed.

Measured From Elsewhere

From symptom onset at 05:40, total time to fibrinolysis was 89 minutes and to angiography 240 minutes. From hospital arrival at 06:41, the time to needle was 28 minutes. Each anchor tells a different story: symptom onset shows the delay before anyone was called, 25 minutes, which no hospital can shorten; first medical contact shows the system's performance; door time shows the critical access hospital's own speed. A brief that switched anchors partway through would make the same night look either fast or slow, which is why the anchor is declared first and kept throughout.

What this page is doingRecomputing the intervals from other anchors shows that the choice of anchor changes the conclusion, which is the point the week closes on.

Lessons for the Record

Two changes would help the next transfer: a single shared time log started by EMS that the hospital continues, and the fibrinolytic checklist begun at the time of the transmitted ECG rather than after the transfer answer. Both would shorten the decision without changing the treatment.

What the PA 518 Week 8 assignment asks for

The final week asks for a timing brief on a reperfusion case. Declare the anchor event first, usually first medical contact, and state the guideline intervals measured from it. Build a timetable near the front with one row per event and columns for clock time, minutes from the anchor and the information available at that moment. Give every row a time, including stretches where nothing is recorded, so gaps are visible. Then work through the intervals in prose, showing each subtraction, and name the one interval that carried the decision. Discuss any transfer or wait in the case. Identify unexplained stretches and suggest how they might be closed. Finish by showing how the intervals would look if measured from a different anchor, such as symptom onset or hospital arrival. Cite the guideline that sets the goals.

How this PA 518 Week 8 example is built

The brief introduces A.K. seven months later, waking at a rural cabin with crushing pressure and reaching a 25-bed critical access hospital. The anchor is EMS contact at 06:17, with the 2025 ACC/AHA goals of 120 minutes to device and 30 minutes to fibrinolysis cited. Table 1 runs sixteen rows from pain onset at 05:40 to angiography at 09:40, including right-sided leads, a declined helicopter, a contraindication checklist and an empty ten minutes. The arithmetic gives 52 minutes to needle from contact, 28 minutes door to needle and 54 minutes door-in-door-out, and shows a direct transfer would have taken about 160 minutes. The unlogged stretch is referred to quality review. Angiography after fibrinolysis is placed in the 2 to 24 hour window, and the intervals are recomputed from symptom onset and door time.

Where the points sit in the PA 518 Week 8 rubric

The rubric for this brief rewards the timetable and the arithmetic. Times missing from rows, or intervals stated without the subtraction, lose the most because the reader cannot audit them. Faculty next check the anchor: it must be declared at the start and used consistently, and switching anchors without saying so is a major deduction. Credit goes to naming the interval that carried the decision and showing why the alternative strategy could not meet its goal. The unexplained stretch earns marks when it is identified and a fix proposed. A section recomputing from other anchors is expected and weighted for showing how the conclusion changes. Guideline intervals must be current and cited, and the table needs a number, title and note.

PA 518 Week 8 help from the desk

The most common setback on this brief is a narrative of the night with times mentioned along the way and no anchor. Send your case timeline and the setting, and the custom sample will declare an anchor, lay out every event in a timetable with intervals and the information in hand, and show each subtraction on the page. It identifies the interval that decided between transfer and fibrinolysis in your case and flags any gap in the record. A final section recomputes the intervals from other anchors so you can see how the story shifts. If your case has missing times, the sample marks them as gaps instead of guessing. Check every clock time against your own case before relying on the arithmetic, and cite the current guideline your course assigns.

PA 518 Week 8 questions, answered

Which event should start the clock?

Your assignment often names it and the brief follows whatever it says. Where the choice is left open, the defensible move is to declare one, give the reason the case supports it, and hold it for every figure afterward. Sections mark the declaration and the consistency far more closely than they mark which of the available events was picked.

Our case has no times at all.

Then the assignment is usually testing whether you notice. Say what is absent, state which intervals cannot be constructed without it, and where the template allows, build the timetable on stated assumptions labeled as assumptions. Send the case as published and the example handles the absence rather than inventing hours to fill it.

Is this brief a discussion of guidelines?

Not in most sections. Where a published pathway is named in your materials it appears as the standard the timetable is measured against, cited to whatever your classroom supplied. What earns points is the sequence and the arithmetic in front of you. These examples describe what an assignment asks for and how it is marked, and they never tell anybody how to treat a patient.

Why was fibrinolysis chosen in the PA 518 Week 8 sample?

With the helicopter grounded, a 95-minute road transfer would have pushed first medical contact to device near 160 minutes, past the 120-minute goal.
