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.

If PQ 20 and QR 22 Then what does PR equal?
To find the length of PR, you can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In this case, PR must be less than the sum of PQ and QR, so PR < 20 + 22 = 42. Therefore, PR could be any value less than 42.
How calculate PQ interval?
To calculate the PQ interval, measure the time from the beginning of the P wave to the beginning of the Q wave on an electrocardiogram (ECG). This interval reflects the time it takes for electrical impulses to travel from the atria to the ventricles. The normal PQ interval duration is typically between 120 to 200 milliseconds. If measured in seconds, you can convert milliseconds to seconds by dividing by 1000.
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.
If PQRS is a rhombus which statements must be true?

Sa node
What is the difference between PR segment an PR interval in EKG?
The difference between intervals and segment is that intervals include the waves,and segments don't.
How do you prove rhs congruence?
Here is the answer to your query. Consider two ∆ABC and ∆PQR. In these two triangles ∠B = ∠Q = 90�, AB = PQ and AC = PR. We can prove the R.H.S congruence rule i.e. to prove ∆ABC ≅ ∆PQR We need the help of SSS congruence rule. We have AB = PQ, and AC = PR So, to prove ∆ABC ≅ ∆PQR in SSS congruence rule we just need to show BC = QR Now, using Pythagoras theorems in ∆ABC and ∆PQR Now, in ∆ABC and ∆PQR AB = PQ, BC = QR, AC = PR ∴ ∆ABC ≅ ∆PQR [Using SSS congruence rule] So, we have AB = PQ, AC = PR, ∠B = ∠Q = 90� and we have proved ∆ABC ≅ ∆PQR. This is proof of R.H.S. congruence rule. Hope! This will help you. Cheers!!!

What is a normal pr interval?
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.
