Study the Heart's Electrical Pathway

Turn your cardiology notes into a branching map that shows each structure and how the signal moves between them.

Build from your own material

Upload a PDF, PPTX or DOCX of your physiology notes and the AI maps the conduction pathway from it.

Follow the signal in order

Branches separate the pacemaker, the conducting pathway and the timing, so you can trace the impulse step by step.

Quiz yourself from the map

Turn the finished map into a quiz on node order, delays and bundle branches before your exam.

How to Build Your Heart Map

Start from your lecture material or a topic, then expand and test yourself on the pathway.

  1. 1

    Add your notes or topic

    Upload a file with your cardiac physiology material, or type the topic conduction system of the heart.

  2. 2

    AI builds the map

    The generator creates a branching map of the nodes, fibers and key timing points.

  3. 3

    Expand, quiz or export

    Expand weak branches with AI, turn the map into a quiz, or export it as PNG or PDF.

Heart Conduction System Explained

The conduction system of the heart is a specialized network of cardiac muscle cells that generates and spreads electrical impulses. The impulse starts at the sinoatrial (SA) node in the right atrium, passes through the atrioventricular (AV) node, then travels down the bundle of His and bundle branches before reaching the Purkinje fibers that stimulate ventricular contraction.

  • SA node: the natural pacemaker, setting the heart rate
  • AV node: delays the signal so the atria empty first
  • Bundle of His: conducts the impulse into the ventricles
  • Bundle branches and Purkinje fibers: spread the signal through the ventricular walls

Use the map to rehearse the order of the pathway and the reason for the AV delay. To build a version from your own lecture notes, create a personalized map with CogniGuide.

Heart Conduction System FAQ

Common questions about the pathway and about building your own map.

What is the normal pacemaker of the heart?

The sinoatrial (SA) node in the right atrium is the normal pacemaker. It fires spontaneously and sets the resting heart rate, usually around 60 to 100 beats per minute in adults at rest.

Why does the AV node delay the signal?

The atrioventricular node slows conduction briefly so the atria finish contracting and fill the ventricles before the ventricles contract. This delay is visible on an ECG as the PR interval.

Which file types can I use to build a heart conduction map?

You can upload PDF, DOCX, PPTX, text or Markdown files, or images of your notes. You can also just type the topic and the AI will build the map.

Can I turn the heart map into a quiz?

Yes. Once the map is generated, you can turn it into a quiz to test yourself on the pathway order. The free plan allows 5 creations a week.
