- 10 year old FN Weimeraner with primary lung mass, seen for echo as cardiomegaly suspected on thoracic rads and was cyanotic with poor recovery from sedation
- Heart seems largely normal. The mitral valve was mildly thickened and the right side of the heart appeared prominent – do you think this is normal?
- The dog was extremely stressed, panting, trying to jump off the table but HR remained between 70-80 bpm.

- I suspect a sinus arrhythmia on ECG, could this be caused by increased vagal tone from lung mass? Would the stress/adrenaline not over-ride this?
- This dog may be going for mass removal so concerned about GA.
- Any thoughts much appreciated.

Hi!
This looks quite normal
Hi!
This looks quite normal to me from a hemodynamic standpoint. The R-waves are a bit high on lead II but given the lack of LV enlargement I would not over-interpret this.
The rhythm seems to be sinus arrhythmia. Any chronic airway disease, GI disease or other vagal stimulation can cause this. We see this sometimes on general anesthesia (maybe stimulated through intubation) . Did the dog get any alpha-2-agonist? like dexdomitor/domitor? Then this could be the cause (reflectory due to incrased peripheral resistance).
I would not worry too much about it. Just have atopine at hand when you anesthetise him.

Thanks Peter. The dog was not
Thanks Peter. The dog was not sedated at time of echo/ecg. She would have been sedated for xrays where lung mass was identified. Thanks again.
