At presentation, HR was 180bpm, no arrhythmia or murmur noted but femoral pulses were weak, no deficits noted.

If the mass causes compression of the PA then less pulmonary blood flow so less flow reaching the left side of the heart and so reflexes kick in and you get tachycardia and as less blood in each CO the femoral pulses are weak.</p></p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/244873?ContentTypeID=1Mon, 10 Jun 2024 11:51:31 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:85245ad6-a9ff-4b87-8378-827bd146be8eAnthony Dennison<p>Sorry for the delay in replying, I&#39;ve been on annual leave for the last 2 weeks and all work related things get put away!</p> <p>I was thinking along the lines of similar treatments to pulmonic stenosis.
