ECG
An ECG (electrocardiogram) records the electrical activity of your pet’s heart, helping us identify abnormal rhythms and assess the heart’s function. It’s a quick, painless and non-invasive test.
What an ECG shows
An ECG is the best way to identify:
- Arrhythmias — irregular, too-fast or too-slow heart rhythms
- Conduction abnormalities — problems with the electrical signals that coordinate the heartbeat
- Some signs of heart enlargement
It complements other heart tests such as listening with a stethoscope, chest X-rays and ultrasound (echocardiography).
When we recommend an ECG
Your vet may suggest an ECG if your pet:
- Has a heart murmur or irregular heartbeat
- Has fainted or collapsed
- Is being assessed before anaesthesia (especially in older patients or breeds prone to heart disease)
- Is being monitored for an existing heart condition
- Shows signs that could be heart-related — exercise intolerance, coughing, breathlessness
What’s involved
An ECG takes only a few minutes. Your pet lies on their side while small clips are gently attached to the skin on the limbs and chest. There are no needles, no shocks, and no discomfort — most pets tolerate it very well without sedation.
We can interpret most ECG traces in the practice, and we have access to specialist cardiology referral if a more detailed assessment is needed.
