why p wave is assuming to be conducting despite short PR interval , Those P wave has less than adequate opportunity to conduct (short PR interval)?
ReplyDelete28:12 – Next Rhythm: Narrow QRS; regular; neg P in II
Hello Mostafa. I believe you are referring to the rhythm near 28:12 in Video-11 — in which there are negative P waves in lead II with a short PR interval. The KEY point, is that since the P wave in this lead II is negative — this is NOT a sinus rhythm. To answer your question — it is because there is a CONSTANT PR interval that we know these P waves ARE conducting. Since they are not sinus — they are either coming from low in the atria, from the coronary sinus or from the AV node. The PR interval may be shorter and still conduct from these sites, since the distance traveled is less than it is with sinus rhythm. Hope that helps in explaining things! — :)
