Source cross-referenced, not independently clinically validated. RhythmDock is not affiliated with, endorsed by, or certified by the American Heart Association. It does not provide ACLS certification or treatment instructions.
Recognition content was cross-referenced on September 13, 2026. AHA 2025 guidance supports the narrow/wide and regular/irregular framework. It does not validate this simulator’s waveform math. PR timing and AV-block morphology are additionally checked against the linked detailed references.
Recognition boundaries
- A wide QRS is 120 ms or longer. Rate alone cannot distinguish SVT, sinus tachycardia or VT.
- An ECG trace alone cannot establish pulseless electrical activity, perfusion or clinical stability.
- SVT and wide-complex tachycardia have multiple possible mechanisms. The simulator shows selected teaching patterns, not exhaustive diagnostic categories.
- The library’s 60 bpm boundary describes sinus bradycardia; an ACLS clinical algorithm’s decision thresholds are a different context.
Artifact categories and interpretation limits; the app uses simplified synthesized examples.
Premature ventricular beats and repeating bigeminy/trigeminy terminology. No treatment content reproduced.
Adult resuscitation terminology, narrow/wide QRS distinction, regular/irregular tachyarrhythmias and recognition limits.
Overview of slowed and interrupted AV conduction.
PR prolongation, Mobitz I/II patterns and AV dissociation.
Irregular ventricular timing and absence of discrete P waves.
Foundational ECG morphology. Not used for current treatment recommendations.
No AHA algorithms, logos, licensed course content or proprietary monitor artwork have been copied into this app. Linked resources may contain clinical management material; RhythmDock itself remains focused on recognition.
