WebbThe P-wave ECG interpretation usually starts with assessment of the P-wave. The P-wave is a small, positive and smooth wave. It is small because the atria make a relatively small muscle mass. WebbNormal ECG Intervals P-R interval. The P-R interval is measured from the beginning of the P wave to the beginning of the QRS complex. The P-R interval represents the time for depolarization of the sinoatrial (SA ) node, the atria, and the AV node. The normal P-R duration is 3-5 small boxes or 0.12 – 0.20 seconds. QRS interval WebbThe T wave on the ECG is the positive deflection after the QRS complex. It represents the repolarization of the ventricular myocardium. To understand the T wave, let’s first briefly go over depolarization and repolarization. Both of these processes represent a shift in the electrical potential and ions of the cells. great lakes ishpeming

The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization. What happens during repolarization of ventricles? As the ventricles repolarize, there is another change in voltage across the cell membrane as the cells become more negative again.

Webb1 nov. 2024 · Every small square on an ECG represents 0.004 seconds. By multiplying 0.004 by the number of squares covered by the space between the start of the P wave and the start of the QRS complex, you can calculate the PR interval. Doctors compare ECG results with normal ranges for the PR interval, QRS duration, QT interval, and RR interval. …

WebbThe P Wave: The P wave of an electrocardiogram (EKG or ECG) represents the depolarization (i.e., contraction) of the atrial muscles. The atria are the top two chambers of the heart. When these muscles contract, the atria pump blood into the bottom two chambers of the heart which are the ventricles.
