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 ...

Upon review of this body and the described ECG findings, certain common patterns ... cocaine use and AV conduction as assessed by PR interval length appears to be somewhat contradictory.

The PR segment is the portion of the ECG from the end of the P wave to the beginning of the QRS complex. The PR segment is different from the PR interval, which is measured in units of time.

ECG plays an important role in detection ... Several markers of atrial or atrioventricular nodal abnormalities such a intervals of P wave, PR, terminal velocity, P morphology, P area and signal ...

1 The majority of disorders associated with increased risk of sudden cardiac death (SCD), such as cardiomyopathies and primary electrical diseases, are suggested by abnormal findings present on an ECG ...
