The PR interval is age-related, and the PR interval should be assessed for abnormalities based on the age of the person being examined.
The atrioventricular junction area has bidirectional conduction ability, and the impulse can be conducted from the atrium to the ventricle or from the ventricle to the atrium.
Because of the slow conduction of atrioventricular node, the PR interval of adult ECG should be greater than 120ms. This physiological phenomenon is called atrioventricular delay.
The PR interval of an ecg includes the time during which supraventricular impulses are transmitted through the atrioventricular node, His bundle, bundle branches, and terminal Purkinje fibers.
Conduction disruption occurs when the impulse encounters the effective refractory period of the downstream conduction system during conduction.
Conduction delay occurs when the impulse encounters a relative refractory period downstream of the conduction system.
