STEMI recognition is time-sensitive — and cognitive overload doesn’t help.
The Life & Sirens STEMI Cheatsheet is a focused, one-page reference designed to support rapid ECG interpretation and infarct localization during high-acuity cardiac calls. This resource organizes ST-elevation patterns by lead group, correlates them with myocardial regions and coronary arteries, and highlights key reciprocal changes that matter in the field.
Built for EMS providers, this cheatsheet is ideal for quick review, education, and reinforcement when seconds count and clarity matters.
ST-elevation patterns by lead group
Infarct location identification (anterior, inferior, lateral, posterior, RV)
Corresponding coronary arteries (RCA, LAD, LCX, LMCA)
Expected reciprocal ST-segment changes
Posterior and right-sided MI recognition
Special patterns (global elevation vs depression, aVR considerations)
ST-elevation measurement thresholds by lead location
Clear visual organization for fast pattern recognition
Reinforces STEMI localization without overcomplication
Supports confident activation and communication
Useful for training, refresher review, and simulations
Designed from a prehospital perspective
📄 Format: Digital PDF download
