Reimagining the 12-lead ECG experience.
We challenged our engineers, clinicians, and data scientists to rethink the 12-lead ECG. The resulting technology underscores our commitment to transform cardiovascular care — simplifying and expediting access to critical cardiac data.

One-cable design + AI trained with one million ECGs.
The FDA-cleared Kardia 12L is an AI-powered handheld 12-lead resting ECG system. With simplified leadset technology, Kardia 12L offers outstanding clinical efficiency that expands access to 12-lead recordings in more settings than ever before.
Its unique single-cable design makes lead placement more intuitive and less error-prone, so even qualified personnel with infrequent ECG experience can acquire an accurate recording in minutes.
And with 1 million ECGs from leading U.S. medical institutions, our team developed a robust algorithm with multiple deep neural network AI models. The Kardia 12L ECG algorithm received FDA 510(k) clearance by demonstrating substantial equivalence to the state-of-the-art 12-lead ECG algorithm.
1. Get started with the KardiaStation app
2. Record a 12-lead ECG
3. Share ECGs for quick review
Lead placement options
Electrodes can be placed on the supine patient in either the Default or Alternate lead set locations. The KardiaStation app will guide you to select the appropriate lead placement, based on patient symptoms. Ensure Right Arm lead is placed first in order for the Leads Off function to display properly.

Comparison to conventional 12-lead results
Standard 12-lead ECG vs. Kardia 12L ECG report
Recent data presented at Heart Rhythm Society 2024, "Diagnostic accuracy of a mobile, artificial intelligence-guided, 12-lead ECG device," showed results from a clinical study on 200 patients. See the side-by-side ECG reports from a standard 12-lead compared to one from the Kardia 12L for the same patients.
The study found that Kardia 12L enabled rapid acquisition of resting ECG information, and concluded "this approach has significant implications for rapid ECG diagnosis in clinical practice."
