You are correct! While difficult to be certain — both the unusual P wave morphology + the very fast atrial rate suggest that rather than sinus tach — this is ATach ( = Atrial Tachycardia). And, we know Wenckebach conduction is quite common with ATach!

I am always looking forward to reading your new writing in this ECG blog. At any time when I read, I always learn new knowlegde from it. Like in this case, I learn the new knowlegde point that the LVH can attenuate the anterior ST depression produced by the acute infero-postero STEMI. In this ECG, I found the atrial activity is very clear with the rate # 145 bpm. I just wonder about it's origin (you didn't mention in your writing). Is it sinus rhythm ( sinus tachycardia) or atrial tachycardia ? I think of sinus tachycardia but I usually see in my daily clinical practice that in infero-postero STEMI the sinus rhythm is usually bradycardic ( I think, because the oclussion of RCA or LCx reduces the perfusion of the SA node) or in normal limit ( 60-100 bpm), not tachycardic . If this is sinus rhythm, why is it so fast ? Or is there any possibility of atrial tachycardia? Thank your sir!Nguyen Chí Tínhhttps://www.blogger.com/profile/10755092672681857950noreply@blogger.com
