A normal PR interval measures the time it takes for electrical impulses to travel from the atria to the ventricles of the heart, typically ranging from 120 to 200 milliseconds (0.12 to 0.20 seconds). This interval is assessed on an electrocardiogram (ECG) and indicates proper conduction through the atrioventricular (AV) node. Prolonged or shortened PR intervals can signify various cardiac issues. Regular monitoring can help in diagnosing potential heart conditions.

What is the length of a normal PR-interval?
The normal PR interval, which measures the time from the onset of atrial depolarization to the onset of ventricular depolarization, typically ranges from 120 to 200 milliseconds (0.12 to 0.20 seconds). If the PR interval is longer than 200 milliseconds, it may indicate a first-degree AV block. Conversely, a shorter PR interval may suggest conditions like pre-excitation syndromes. Regular monitoring is important to assess any potential underlying cardiac issues.
What is a prolonged PR interval?
A prolonged PR interval is a condition observed on an electrocardiogram (ECG) where the time taken for electrical impulses to travel from the atria to the ventricles is longer than normal, typically exceeding 200 milliseconds. This can indicate a delay in the conduction through the atrioventricular (AV) node and may be associated with various heart conditions, such as AV block. While it can be benign in some cases, a prolonged PR interval may require further evaluation to determine its underlying cause and potential implications for heart function.

What is the significance of this PQ (PR) interval?
The PQ (PR) interval represents the time it takes for electrical impulses to travel from the atria to the ventricles in the heart. Measured on an electrocardiogram (ECG), it reflects the conduction time through the atrioventricular (AV) node. A normal duration indicates proper electrical function, while a prolonged or shortened interval can signal potential heart conditions, such as AV block or pre-excitation syndromes. Monitoring this interval is crucial for diagnosing and managing various cardiac issues.
