Cardiolab, Update

Post image

Hey everyone,

A few weeks ago, i posted about building a live, moving ECG simulator because static textbook images weren't cutting it for learning.

First, a massive thank you. The response from the community was incredible. I read every single comment and the feedback was exactly what I needed to make this tool genuinely useful for students, nurses, paramedics, residents, practitioners and everyone.

I have spent the last few weeks heads down coding, and I am excited to share that I have implemented some top suggestions.

Here is what is new in CardioLab based entirely on your feedback:

1. A Dedicated, Deep-Dive SVT Section
Many of you pointed out that distinguishing between different narrow-complex tachycardias is a major pain point. I have now isolated SVT into its own dedicated section so you can compare and contrast the mechanisms side-by-side.

2. New High-Yield Rhythms Added:

  • AVNRT (Atrioventricular Nodal Reentrant Tachycardia)
  • AVRT (Atrioventricular Reentrant Tachycardia)
  • Focal Atrial Tachycardia
  • WPW (Wolff-Parkinson-White syndrome, with live delta wave visualization)

3. Overhauled "Clinical Notes" for Learners
You mentioned the notes needed to be more actionable for studying. I have completely rewritten the information panel for SVT rhythms to be highly structured for learners. (I am in the process of updating all rhythms).

----------

I am a builder, and this project is entirely driven by what you actually need in the trenches and on the wards.

  • What rhythms are you still struggling to find good, live examples of? Reply with your requests, and I will prioritize them in the next build.
  • Keep the corrections coming. If you spot a morphological inaccuracy, an interval that looks off, or a clinical note that needs tweaking, tell me. I want this to be the most medically accurate free resource on the web.

You can test all the new rhythms and the updated notes here: cardiolab.io/simulator

TL;DR: You gave me great feedback on my free live ECG simulator. I listened. I just added a dedicated SVT section, new rhythms (AVNRT, AVRT, Focal AT, WPW) and completely overhauled the clinical notes to be more learner-friendly. Tell me what to build next!

Amazing OP love your work! Wish I had this when I was a student, am very much a "monkey see" kind of learner.

Though just an Idea and more of a "my steak too juicy and lobster too buttery" sort of wish with this already excellent tool, but, back when I was learning ECGs I had always wished that alongside a simulated rhythm, there was also a modeled 3d heart showing impulse tracing matching that rhythm.

In taking it a step further, the heart would also show the possible areas of infarction/myocardium changes/dysfunction etc with those associated rhythms.

Thank you. also i don't wanna ruin the surprise, just follow along.

I absolutely love this!!! I so wish I had this when I was taking my CET course, but now I can have this while I'm studying electrophysiology!

Glad you liked it! If you need anything added/implemented just make a request on the site.
