Top best answers to the question «Is there always one p wave for every qrs complex»
Variations of second-degree AV block
In blocks with 2:1 conduction, two P waves occur for every QRS complex, indicating every other impulse is blocked, as shown in the strip below. With every other P wave being conducted, this rhythm has regularly occurring QRS complexes.
- There's one P wave for each QRS complex. And if we measure our PR interval here, then we will see that it is within the range of three to five small boxes high and that the QRS complex is nice and narrow; it is under three boxes wide.
