Cardiac arrhythmia diagnosis and treatment in dogs Specialists in Australia

Cardiac arrhythmias are abnormalities of the heart's electrical system that cause it to beat too fast, too slow, or irregularly. Some are benign and incidental; others cause syncope (fainting), exercise intolerance, or sudden death. Specialist veterinary cardiologists use ECG, echocardiography, and 24-hour Holter monitoring to diagnose arrhythmias accurately and decide when and how to treat them.
