WebIn addition to the P wave, QRS complex, and T wave, other features of ECG signals can also provide important information about cardiac function. For example, the PR interval represents the time between the start of the P wave and the start of the QRS complex and can indicate abnormalities in atrioventricular conduction. WebA pathologic Q wave is defined as having a deflection amplitude of 25% or more of the subsequent R wave, or being > 0.04 s (40 ms) in width and > 2 mm in amplitude.
