In theory — the ventricular...Excellent question JJ! In theory — the ventricular escape pacemaker would have taken over — but keeping in mind that the ventricular escape pacemaker is the “lowest escape site” — it was “behaving” after seeing a sinus conducted beat. Most probably IF the junctional escape site had not “woken up” — then this ventricular escape site would have reappeared a little bit later at the 1480 escape interval. There may be a slight “delay” until you see a given escape focus. That is LESS likely to happen when you have AV dissociation by “usurpation” from an accelerated escape focus.<br /><br />Hope the above makes sense. It just isn’t always exactly as we think it “should be” (ie, “Why is the sky blue?”) — but I bet the ventricular pacemaker would have kicked in later had the AV nodal escape not reappeared … — :)ECG Interpretationhttps://www.blogger.com/profile/02309020028961384995noreply@blogger.comtag:blogger.com,1999:blog-3364570834099131201.post-89395626608831510802022-09-17T09:16:45.629-04:002022-09-17T09:16:45.629-04:00Wanted to ask, if the rate of ventricular escape i...Wanted to ask, if the rate of ventricular escape is 1480 and junctional escape is 1530, why the ventricle didn't takeover the rhythm at 1480 period after the sinus capture beat?JJhttps://www.blogger.com/profile/17519255052010474217noreply@blogger.comtag:blogger.com,1999:blog-3364570834099131201.post-48187844935877390632022-09-14T19:02:39.664-04:002022-09-14T19:02:39.664-04:00 I am as always amazed and and learnt a lot I am as always amazed and and learnt a lotPlus Ultrahttps://www.blogger.com/profile/01735827112800682222noreply@blogger.com
