The PR segment is the flat line between the end of the P-wave and the start of the QRS complex. The PR segment reflects the time delay between atrial and ventricular activation. The PR segment also serves as the baseline ( reference line or isoelectric line) of the ECG curve.

represents: atrial contraction. duration: 0.12-0.20 sections (3 little boxes - 1 big box) QRS Complex. represents: ventricular depolarization. The PR interval represents the atrial depolarization and physiological delay of the stimulus in the atrioventricular (AV) node. It is measured from the beginning of the P wave until the beginning of the Q or R wave. Its normal value is between 0.12 s and 0.20 s. It is actually wrong to call this symptom a depressed PR interval as it is the space between the end of the P wave and the start of the QRS complex that shows anomalies.

The ST segment represents the heart's electrical activity immediately after the right and left ventricles have contracted, pumping blood to the lungs and the rest of the body. Following this big effort, ventricular muscle cells relax and get ready for the next contraction.

This video explores the various segments and intervals seen on an ECG tra What does the P-R segment on an ECG represent? The time that the ventricles are fully depolarized The time between cardiac cycles The time it takes for the electrical impulse to travel from the AV node to the ventricle The repolarization of the ventricles The depolarization of the atria Question 19 What is recorded on an electrocardiogram? The PR interval on the electrocardiogram reflects atrial depolarization and AV nodal delay which can be partially differentiated by P wave duration and PR segment, respectively. GWAS have identified a number of genetic loci for PR interval but it remains to be determined whether this is driven by P wave duration, PR segment or both. Open Menu Close Menu.

The PR segment also serves as the baseline ( reference line or isoelectric line) of the ECG curve. P-R segment. The line on an electrocardiogram that begins with the end of the P wave and ends with the beginning of the QRS. It corresponds to the period between the end of atrial depolarization and the onset of ventricular depolarization. See also: segment. PR segment: represents time from end of P wave to start of QRS complex.

The ST segment is the line that from the end of the QRS complex to beginning of the T wave. ST segment: This segment starts at the J-point. The J-point is where you start to see an upward stroke after the S wave. The segment ends at the beginning of the T-wave. The ST-segment represents when the ventricles are relaxing, also called repolarizing. Now test your knowledge on how well you grasp the material by taking this quiz.
