Why is the shape of the P wave analyzed?
To determine whether atrial depolarization occurred and if the atrial
impulses caused the ventricular contraction.
What question is necessary to analyze a P wave on an ECG tracing?
Does each P wave have a QRS complex following it?
What is the normal PR interval measurement?
0.12 to 0.20 seconds.
