Interactive training for acute and emergency care, built by clinicians who work the shifts. Every waveform is simulated from physiology — nothing here comes from a patient.
What we make
Each product teaches a single skill properly, instead of covering everything shallowly. They share a look, a login and a rule: understanding before memorising.
ECG interpretation
Place a thrombus in the coronary tree and watch the infarct evolve. A 3D heart that beats along with the rhythm you pick. Forty-two rhythms, electrode placement, and a practice lab where you compare two ECGs from the same patient minutes apart.
Available now Visit BeatLabStroke assessment
A stroke simulator for practising the NIH Stroke Scale: work through a case, score each item, then see where your score differs from the reference — and why that item is one experienced clinicians disagree on.
In developmentNot available yet. We will not put a date on it before the clinical review is finished.
Sport
Scoring and tournament tracking for beach volleyball. Built for a phone at the side of the court, in one hand, in bright sunlight — and it keeps working without a signal.
Available now Open BeachappIn the works
These go beyond the trainers and will be a separate, more advanced tier. Neither gets a release date from us before its clinical review is finished.
Structured course
Eight interactive lessons that build the reading in order: anatomy first, then why the pathology changes the trace, then the patterns themselves. Every lesson is something you work through, not a slide deck with a quiz at the end.
In developmentWritten and tested. Waiting on clinical sign-off before it goes out.
Volume practice
A thousand real, de-identified ECGs to read one after another, with structured reporting and immediate feedback on where your reading differs from the reference. Recognition only becomes automatic at volume — a handful of teaching examples will not get you there.
In developmentThree independent readers are working through the set first. Until that is finished, we do not consider the reference reliable enough to teach from.
Why we build this
We wanted to show the mechanism.
Open almost any ECG course and you get a gallery of finished pictures: this is an inferior infarct, this is a bundle branch block, learn to recognise them. It works — until you meet a tracing that does not look like any of the pictures.
What is missing is the step in between. Why does that vessel produce that pattern in those leads? What happens to the trace in the twenty minutes after the occlusion? Move an electrode two ribs up and what changes, exactly?
Those questions have concrete answers, and they are far easier to remember than a gallery. So we built tools where you can do the thing instead of looking at the result: place the thrombus yourself, move the electrode yourself, and watch all twelve leads answer.
Built on the ambulance, between calls — because that is where the gap between “I recognise this” and “I understand this” actually costs you.
AcuteLabs is the work of Dennis Sagel, ambulance nurse and researcher. The products come out of teaching colleagues and out of research into prehospital chest-pain triage — not out of a product plan.
Who it is for
Not a general public product. Everything assumes you already know what a QRS is.
How we build
They cost us features. We keep them anyway.
The ECGs in our trainers are generated by a simulator built from physiology. Where we use real recordings — in the coming 1000 ECG training — they come from PTB-XL, a public research dataset that was de-identified and published for exactly this purpose under an open licence. We never use recordings from our own patients, and nothing a learner sees can be traced back to a person.
Our tools teach interpretation. They are not diagnostic software, they are not a medical device, and they are not meant to guide the care of a real patient. Where that line runs, we say so in the product itself.
Clinical content is checked by people who do the work before it reaches a learner. Where something is still under review, we mark it as such rather than quietly shipping it.
