The cycle of depolarization and repolarization is extremely rapid, taking only about 2 milliseconds (0.002 seconds) and thus allows neurons to fire action potentials in rapid bursts, a common feature ...

This realization led her into the nonprofit world and to Braver Angels —a grassroots organization dedicated to depolarization—where she is director of digital and storytelling. It also provided her ...

Remember the QRS complex indicates ventricular depolarization; thus the PR interval will be prolonged. The PR interval is normally between 0.12 and 0.20 seconds.

The time from the beginning of the P wave, indicating atrial depolarization, to the beginning of the QRS complex, representing ventricular depolarization, is the PR interval. This represents the ...
