Post-ROSC ECG often misses occlusive MI
The post-ROSC ECG: morphological spectrum of non-ST-elevation occlusion and prognostic markers after cardiac arrest
Resuscitation · 2026-11 · Added 26 September 2026
A retrospective single-centre study of 214 post-ROSC patients found nearly half of angiographically confirmed occlusive infarctions showed non-ST-elevation OMI patterns, and PR-segment prolongation independently predicted reduced 30-day survival.
- Study type
- Cohort
- Design
- Retrospective single-centre cohort
- Participants
- 214 cardiac arrest survivors admitted to a tertiary ICU (101 with angiography-confirmed OMI)
- Main finding
- NST-OMI patterns made up 48% of confirmed OMI cases and underwent angiography less often (78% vs 98%); PR-segment prolongation was independently associated with reduced 30-day survival (aOR 0.977 per ms)
- Caveat
- Single-centre, hospital-side ECGs only, retrospective design with angiography as reference
- Bottom line
- Hypothesis-generating
Why it matters in Australia (Medium relevance). The post-ROSC ECG is taken prehospital, so recognising NST-OMI patterns could shape cath-lab activation, but the analysis was done on ICU-admitted survivors and needs prehospital validation.
Learning goal
Strengthen my interpretation of subtle post-ROSC ECG patterns so I recognise occlusive infarction without ST elevation.

No evidence on screening arrest survivors' psychology
Systematic review of structured identification and assessment of psychological, emotional or cognitive problems in cardiac arrest survivors — of 1,605 records screened, none met eligibility, so there is no evidence base for which screening instruments, thresholds, timing or referral pathways should be used.
