- 9 year old FN Collie who has developed exercise intolerance. History of diaphragmatic hernia repair years ago
- She will be need to lie down during exercise (can’t move further even though really wants to get up) and pants heavily at this time. Also panting more at rest.
- Bradycardic on PE, HR around 40-50 but can increase to 60+ when stimulated
- Bloods, thoracic and abdominal xrays, abdominal scan (done by inhouse vet) and echo all wnl
- ECG showed sinus bradycardia with deep t waves, is this artefact or relevant?

- Could this be a sick sinus syndrome? no tachycardia noted.
- Holter is the next step, is there anything that should be considered prior to this?

Hi

Hi
Based on this ECG I would look for right heart disease or Hyperkalemia first. The recording does not really support the theory of Sick Sinus Syndrome since the P waves look normal. However, a Holter ECG would be necessary to rule out SSS – and I would recommend a Holter anyway if echo and potassium are normal.
Hope that helps!
