Apologies if this is not right to post on an ultrasound forum.
I have done an echo on this young Rhodesian Ridgeback that presented to the pre-desexing clinical examination and the clinician noted an irregular rhythm on auscultation. The dog is asymptomatic and fully grown.

I am struggling to see P waves for each QRS complex here, and sometimes I think they are of negative conformation in L II. Also, the long pauses appear longer than the previous RR interval. Are this junctional scape complexes with sinus arrest pauses? Is this finding significant since no haemodynamic abnormalities noted on the echo / history? Would an atropine test be indicated to check appearence of normal P waves?
Thanks for your thoughts,
Silvana

Dear Silvana!
Thanks for
Dear Silvana!
Thanks for this ECG!
You’re right: P-waves cannot be consistently seen here and the base line is irregular. The rhythm is an absolute arrhythmia (irregularly irregular). I’m pretty sure that this is afib. afib can sometimes be found in large breed dogs without echo abnormailities. But I would kindly ask you to send the ECG to my personal email address too (Eric has it) so that I can enlage the ECG. This would help me a lot.
Best regards!

Thank you Peter.
I had it
Thank you Peter.
I had it reviewed by a cardiologist and he confirmed an AF lone. I never heard of this AF before, my understanding was that the HR should be higher than 200 at least.
But, I ‘ve learnt the AF was the reason why I could not see an E wave on the CW of the MV, or on the M mode of the MV !
Thank you for offering reviewing the ecg anyways,
Cheers,

Thank you for your post! I’m happy that the cardiologist agrees with my diagnosis 🙂 Sorry for my delayed initial comment!
afib at a heart rte >180 on exam or >140 at rest is tachycardic afib. But afib can as well have a normal heart rate as well. Or it can occur in combination with an AV-block.
