Interpret
10-step guided ECG wizard. Enter your findings and watch a live differential build in real time — from calibration to ST changes and clinical context.
Differentials
Tabbed ECG differential library — ST elevation, arrhythmias, heart blocks, morphology, intervals, and metabolic. Expandable cards with criteria and teaching pearls.
Library
ECG pattern library with category filters. Reference cards for common and rare rhythms with diagnostic criteria, mimics, and management pearls.
Criteria & Scores
Diagnostic ECG criteria — STEMI, Sgarbossa, de Winter, Wellens, Brugada and more. Clinical scores — HEART, TIMI, GRACE, CHA₂DS₂-VASc, Wells PE. Pitfalls and pearls for each.

Drug Effects
How common drugs change the ECG — QT prolongation, digoxin toxicity, TCA overdose, antiarrhythmics, cocaine, beta blockers. Searchable with risk levels and clinical pearls.
Electrolytes
Interactive sliders show live ECG morphology for K⁺, Ca²⁺, and Mg²⁺ at any level — from peaked T waves in hyperkalemia to short QTc in hypercalcemia.

Beyond the basics
Chronicles
The pioneers, milestones, and myths that shaped cardiology — from Harvey's blood circulation to the first heart transplant. With portraits of the people who changed medicine.
Comedy Ward
Cardiology jokes, husband & wife classics, and boyfriend & girlfriend moments — all with an ECG twist. Because laughter is the best antiarrhythmic.
Why It Exists
From ECG findings to differential, management, and report.
Most ECG resources teach patterns. EKG Compass teaches the clinical workflow: quality, leads, rhythm, rate, axis, intervals, morphology, ST-T changes, context, then a final impression. 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
Learners practice saying the interpretation clearly.
