Autonomic tone
Controls that mostly shape sinus rate, respiratory coupling, and baroreflex-style variability.
Neurocardiac ECG Lab
The surface tracing is now framed through autonomic tone, respiratory coupling, and AV nodal braking. Instead of only tweaking voltages, you can move through realistic vagal and sympathetic teaching states, then inspect how those shifts alter the ECG paper, rhythm strip, and cardiac vector.

Paper speed
Lead layout
Faster paper speeds show fewer milliseconds across the same screen width, which makes interval inspection feel much closer to bedside ECG review.
Consult frames
These frames push the lab beyond parameter twiddling. Pick the consult scenario, load the aligned physiology, and then decide what the strip is really saying versus what it could be mistaken for.
Syndrome frame
The tracing is fast, relatively fixed, and catecholamine-weighted. The teaching question is whether the ECG is reflecting primary cardiac disease or an autonomic response to acute CNS injury or severe stress physiology.
Highest-yield next data
Compare mode
Best mechanism
Central sympathetic surge with neurocardiac spillover, producing a tachycardic and repolarization-shifted surface pattern.
Weaker alternative
Primary ACS by ECG appearance alone
An isolated tracing cannot outrank the physiology. When sympathetic context is overwhelming, repolarization distortion can be secondary and demands correlation rather than reflexively becoming the diagnosis.
Autonomic tone
Controls that mostly shape sinus rate, respiratory coupling, and baroreflex-style variability.
Conduction timing
Intervals that change AV nodal delay, depolarization width, and repolarization timing.
Morphology and acquisition
Amplitude and projection controls that shape what the surface leads record and how strongly they appear.
3D cardiac activation
Lead constellation
Representative beat phase
Generate ECG to animate a representative beat.
