Turn your heart physiology notes into a concept map
Upload lecture slides, a textbook PDF, or photos of notes. DeckOwl builds an editable mind map that traces the signal from the SA node to the Purkinje fibers.
How the heart's electrical signal travels, step by step
Students often memorize the electrical activity of the heart as a list of names, then lose the order. A concept map of the electrical activity of the heart shows the path instead: the sinoatrial node fires, the signal spreads across the atria, pauses at the atrioventricular node, runs down the bundle of His, and reaches the Purkinje fibers.
- SA node sets the normal rate, usually 60 to 100 beats per minute.
- AV node delays the impulse for about 0.1 second so the atria empty first.
- Bundle branches carry the signal down both sides of the septum.
- Purkinje fibers spread the impulse through the ventricles from the apex upward.
Reads your source material
Upload PDF, DOCX, PPTX, plain text notes, or a photo of a page. Text recognition reads handwritten-style photos of printed pages.
Editable branches
Rename, move, or add nodes such as the P, QRS, and T waves. The map stays yours to reshape before you study it.
Explorable structure
Expand and collapse branches to focus on one stage of conduction at a time, then quiz yourself on the order of events.
How it works
Upload your notes
Add a lecture PDF, slides, or typed notes on cardiac conduction.
Generate the mind map
DeckOwl pulls the main branches from your material into a connected map.
Edit and study
Adjust the branches, then explore the map in your browser. Plus adds PDF, DOCX, and Anki export.
Upload a PDF, DOCX, PPTX, plain text notes, or a photo of a page, and the generator builds the branches from your material. Each node can be edited, reordered, or expanded, so you can add the P, QRS, and T waves your course covers.
Once the map is built, click through the branches to test yourself on the order of events. Use it as a quick review before an exam, then return to the sequence when a question mixes up the nodes.

Frequently asked questions
What sets the normal heart rhythm?
The sinoatrial node in the right atrium fires spontaneously and sets the rate, usually 60 to 100 beats per minute. Its impulse spreads through the atria, then reaches the AV node.
Why does the AV node delay the signal?
The delay of about 0.1 second lets the atria finish pushing blood into the ventricles before they contract. Tracing the path from SA node to Purkinje fibers helps you remember why the order matters.
Can I export my heart mind map?
Exports to PDF, DOCX, Anki, and CSV are part of the Plus plan at $39 per year or $7.99 per month. The free plan lets you study generated maps in the browser with 3 generations per month.
Do I need a credit card to try it?
No. You can start on the free plan without a credit card. Students with a school email get 40% off paid plans.
