WebbAn interval in an ECG is a duration of time that includes one segment and one or more waves. The PR (or PQ) interval starts at the start of the P wave and ends at the start of the QRS. It denotes the conduction of the impulse from the upper part of the atrium to the ventricle. The QRS interval covers the QRS complex from beginning to end.

WebbThe P wave represents the wave of depolarization that spreads from the SA node throughout the atria and is usually 0.08 to 0.10 seconds (80-100 ms) in duration. The brief isoelectric (zero voltage) period after the P wave represents the time in which the impulse is traveling within the AV node (where the conduction velocity is retarded) and the … Webb10 apr. 2024 · “Dark Wave,” hosted by Slicing Up Eyeballs’ Matt Sebastian, airs 10 p.m. to 1 a.m. Eastern every Sunday on Sirius XM satellite radio’s 1st Wave (Channel 33).

This represents a compensatory pause following a PAC. We cannot see the first post-ectopic P wave, because it is hidden in the S wave of the PAC. Now let’s move on to the second PAC.
