Purkinje fibers yog cov tes hauj lwm ntawm fibers uas tau txais cov cim hluav taws xob los ntawm lub atrioventricular node atrioventricular node Lub atrioventricular node los yog AV node yog ib feem ntawm cov hluav taws xob conduction system ntawm lub plawv uas coordinates saum lub plawv. Nws hluav taws xob txuas lub atria thiab ventricles. https://en.wikipedia.org › wiki › Atrioventricular_node

(AVN), thiab ib txhij qhib sab laug thiab sab xis ventricles los ntawm ncaj qha stimulating lub ventricular myocardium.

Purkinje fibers muaj nuj nqi dab tsi?
