How Hearts Electric system Work?

Описание: Heart's Electric system? what is pacemaker?
The heart is not just a pump — it has its own natural electrical system that controls every heartbeat! ❤️ In this video, we’ll explain step by step how the heart’s electrical conduction system works, including the SA node (pacemaker), AV node, Bundle of His, Purkinje fibers, and ECG (electrocardiogram).

You’ll learn:
✔️ How electrical signals start in the SA node and spread across the atria
✔️ Why the AV node delays impulses to allow proper filling of ventricles
✔️ How the Bundle of His and Purkinje fibers spread signals for a strong contraction
✔️ The link between electrical activity and the heartbeat you hear
✔️ How doctors measure the heart’s rhythm using an ECG
