Choose the correct flow of impulse transmission in the human heart?

انسانی دل میں تسلسل کی ترسیل کے صحیح بہاؤ کا انتخاب کریں؟

SA node → AV node → Purkinje fibers → Bundle of His

AV node→ SA node → Purkinje fibers → Bundle of His

SA node → AV node → Bundle of His → Purkinje fibers

None of these

The SA node initiates the impulse, which travels to the AV node and then to the Bundle of His.

Finally, it spreads through the Purkinje fibers, causing ventricular contraction.
