– 10 year old MN Cockapoo with a very irregular arrhythmia on auscultation found on routine wellness exam
– no clinical signs of heart disease, no murmur, not unwell at all
– bloodwork pending
– echo – pretty normal except for mild- moderate TR with max vel. 2 m/s; normal LA, normal LV, right heart unremarkable, Aorta and PA velocities normal (would post but nothing exciting to show!)
– so this does not appear to be due to structural heart disease
Any thoughts on what may be causing this?

Hi!
Very difficult to read – there seems to be a lot of “baseline-compensated” artifacts. The QRS complexes are narrow and there seems to be a P-wave in front of every QRS-complex and the other way around. Still, I cannot determine the PQ-intervals because I cannot enlarge the ECG sufficiently. Could be either Sinus-arrhythmia or some supraventricular arrythmia. A at least 3-lead ECG would be required here. I think the varying QRS-amplitudes are artificial (no pericardial effusion was visible…)
Sorry for this kind of nebulous interpretation – sometimes I envy the human doctors their compliant patients 🙂
Best regards!

Thanks Peter!

Thanks Peter!
The patient was highly stressed, panting profusely so I imagine there is alot of “junk” in the ECG. Sorry for the small size! We have recommended a Holter monitor as it may be better to see how this patient is at home in his own environment. Definitely no pericardial effusion on the echo.
I did end up sending the ECG to a cardiologist (who got the larger original size) the interpretation was:
Intermittent atrial premature beats and occasional runs of supraventricular tachycardia.
Average sinus rate is about 150- 160 with a sinus arrhythmia. SVT rate approaches 280bpm as an instantaneous R-R interval. There is occasional second degree AV block.
