How does the electrical impulse travel through the heart
Moves through atria causing contraction (P-wave), then it is received by AV node, delayed (P-R interval). Stimulus is sent through bundle of His and L&R bundle branches to purkjunke fibers (QRS) after short delay (S-T) the heart depolarizes (T-wave).
