Welcome to HeartVets

*** COVID-19 UPDATE ***

We pleased to announce we are open in most of our regular referral clinics, seeing patients as usual, though in a COVID-safe manner. We are able to accept referrals as usual - please call us for more details, or submit a referral request form using the button on the left.

We are here to help you manage your cases remotely as always, to ensure you still get the same specialist-led referral guidance for your clients and patients. Please call or email us for assistance and telemedicine reports.

HeartVets is a specialist-led cardiology consultancy service for assessment and treatment of cardiorespiratory problems in veterinary patients, predominantly dogs, cats and horses.


The team is led by Dr. Mark Patteson, Jo Harris and Dave Dickson, who are all RCVS (Royal College of Veterinary Surgeons) Specialists in Veterinary Cardiology.


We are based at Vale Referrals in Dursley, Gloucestershire, where we offer a 24-hour emergency service supported by a fully equipped multidisciplinary  referral hospital. We also offer satellite clinics at referral hospitals and veterinary practices throughout the south-west UK and Wales, as well as a mobile cardiology service for visiting horses.

To help you manage cardiology cases in-house we offer online ECG and radiograph reporting as well as Holter monitor rental and analysis for dogs and cats. Click here for more information about our diagnostic and Holter monitoring service.


If you are concerned that your pet may have a heart or lung problem, speak to your vet about arranging a referral to see one of our cardiologists.
