ECG Cath Lab Activation Study
You will review 12-lead index ECGs from consecutive cardiac catheterization-lab activations at three US centers — the same cohort presented at the TCT 2025 late-breaker and published simultaneously in JACC: Cardiovascular Interventions. For each ECG, decide whether you would activate the cath lab, then compare your performance against the reference standard and the AI model.

Reference standard — "true STEMI"
Angiographically confirmed true STEMI was adjudicated from all available clinical data and required:
- Positive high-sensitivity cardiac troponin — any value above the assay-specific 99th-percentile upper reference limit with a serial rise and/or fall.
- Angiographic culprit vessel identified by the operator (≥70% stenosis or TIMI flow grade 0 or 1).
- Also includes MINOCA due to vasospasm, coronary embolization or spontaneous coronary artery dissection.
