❤️⚡ Your heart’s electrical system is a masterpiece of coordination!

It all starts with the SA node, the heart’s natural pacemaker, generating the rhythm. 🎶 Then, the AV node steps in as the traffic controller, slowing the signal to let the atria fill the ventricles. 🚦

Next, the Bundle of His acts like a bridge, carrying the signal to the ventricles, while the Purkinje fibers spread it like an express highway, ensuring a synchronized and powerful heartbeat. 🚀

From connexin proteins to sodium channels, these structures work together to keep your heart pumping efficiently—and even act as backup pacemakers if needed! 🌟

Discover how this intricate system is vital for anesthesiologists to optimize patient care during surgery. 🩺💉
