Quizplus · Accepted Answer

Segments in an ECG pattern are portions of the tracing that do not include the waves or complexes, such as the PR segment, which is the flat line between the end of the P wave and the start of the QRS complex. Intervals, on the other hand, include waves and the following segment, such as the PR interval, which includes the P wave and the PR segment, reflecting the time from the onset of atrial depolarization to the onset of ventricular depolarization.
