What a normal pri measurement?

A normal PRI (P-R interval) measurement on an electrocardiogram (ECG) typically ranges from 120 to 200 milliseconds. It represents the time taken for electrical impulses to travel from the atria to the ventricles, indicating proper conduction through the heart's electrical system. Values outside this range may suggest various cardiac conditions, such as atrioventricular block or other conduction abnormalities. Regular monitoring of the PRI can be crucial for assessing heart health.
