Why EKG Compass
Why It Exists
From ECG findings to dangerous differentials, management, next steps, and report.
Most ECG resources teach patterns. EKG Compass teaches the clinical workflow: quality, leads, rhythm, rate, axis, intervals, morphology, ST-T changes, context, supporting findings, dangerous differentials, acute management, and a copyable final report. Learners practice the same order every time until ECG interpretation becomes reliable.
Live differentials
The differential updates as findings are entered.
Management next steps
ACS, rhythm, electrolyte, and conduction pathways connect to action.
Copyable report
Includes findings, differentials, management, next steps, and internal links.
Built For
Medical students
Move beyond memorizing patterns into a reproducible ECG method.
