Interactive EKG course
Stop matching
pictures.
Start measuring.
Most EKG courses teach you to recognize twelve pictures and hope the patient cooperates. This one teaches the thing experts actually do — put calipers on the paper and reason from the numbers.
PR
Pattern-matching
breaks at 3 a.m.
Recognition works until the strip is noisy, the rate is odd, or the patient has two things wrong at once. Measurement doesn't have that failure mode. A number is a number at any hour.
Recognition
"This looks like the SVT strip from the slide deck." Fast, confident, and wrong the moment the picture shifts — artifact, an unusual axis, a rate between the two examples you were shown.
Measurement
"R–R is 20 mm, so 75 bpm. PR is 4 small squares — 160 ms, normal. QRS is narrow." Same method every time, and it tells you when you're outside what you know.
QRS
Drag the calipers.
This is the whole method in one control. Grab either leg, span an interval, read the number. Every lesson in the course ends with you doing exactly this.
Drag a leg, or pick a measurement below.
ST
Break a heart on purpose
This is a real module from the course, running here in full. Every tracing is generated from a parametric model, so you can push an interval until it becomes a diagnosis and watch which flags trip.
T
Eight modules, one method
Anatomy of one beat
Isolate each component, then deform it with sliders and watch the interpretation flags change in real time.
Graded caliper practice
Randomized tasks with real tolerances. The strip knows its own true intervals, so the feedback is exact.
Both rate methods
The 300 rule and the 6-second count, with the module telling you which one the rhythm actually permits.
Twenty rhythms
Sinus through asystole, each with distractors chosen to be the ones people genuinely confuse it with.
Draggable axis
Move the mean vector and six leads rewrite themselves live. Projection stops being abstract.
Territories and vessels
Full twelve-lead cases with reciprocal changes modeled, not just elevation drawn in.
Mixed drill
Strips and twelve-leads shuffled with no warning which is next — the only honest test format.
The reading order
The eight-step sequence to run on every tracing, plus the numbers worth knowing cold.
A complete learning experience
All eight modules share one engine, so what clicks in Anatomy shows up again in the Mixed drill. Nothing here is learned in isolation.
Built for anyone
learning the paper
The method doesn't change by credential. Depth does — you choose how far past the fundamentals to go.
