As a medical professional with expertise in cardiology, I can explain that a short PR interval refers to a duration on an electrocardiogram (ECG) that is less than the normal range. The PR interval represents the time from the start of the P wave to the start of the QRS complex, which reflects the time it takes for an electrical impulse to travel from the atria to the ventricles of the heart. A normal PR interval is typically between 0.12 to 0.20 seconds. A short PR interval indicates this conduction time is faster than usual, which can be associated with certain conditions such as pre-excitation syndromes, hyperthyroidism, or it may be a normal variant in some individuals. It's important to note that a short PR interval is not always indicative of a problem and may require further evaluation by a healthcare provider. read more >> -

A short A-V conduction time, whether present with normal or with abnormal QRS complex, is associated with an increased incidence of paroxysmal rapid heart action. There are a considerable number of patients who have a short P-R interval, normal QRS complex and bouts of tachycardia.read more >>
