ECG Rhythm & 12-Lead Library
Every one of the 30 single-lead cardiac rhythms plus the available 12-lead conditions in the CardioLab simulator. Each opens an interactive, real-time ECG with recognition criteria, mechanism, and clinical notes.
Sinus Node
Atrial Ectopy
Atrial Arrhythmias
AV Blocks
- 1st Degree AV BlockProlonged PR interval (>200ms)
- 2nd Degree AV BlockProgressive PR lengthening, periodic dropped QRS
- 2nd Degree Type II (Mobitz)Fixed PR, periodic dropped QRS
- 2:1 AV BlockEvery other P wave blocked, fixed ratio
- 3:1 AV BlockOnly every 3rd P wave conducts, high-grade block
- 3rd Degree (Complete) AV BlockAtria and ventricles fire independently
Junctional & Escape
Ventricular Ectopy
Ventricular Tachyarrhythmias
- Monomorphic VTRapid wide-complex rhythm
- Non-Sustained VTShort VT bursts interrupting sinus rhythm
- Polymorphic VTContinuously varying QRS morphology
- Bidirectional VTAlternating QRS axis, two ventricular foci
- Torsades de PointesSpindle-shaped polymorphic VT, twisting QRS axis
- Ventricular FibrillationChaotic disorganized rhythm, no effective output
Terminal
12-Lead Conditions
Full 12-lead simulations with live diagnostic criteria across all twelve leads.
