The veterinary cardiologist will start with a complete physical exam. Canine or feline heart murmurs can often be heard and detected with a simple stethoscope. The veterinary cardiologist will also listen to your pet's lungs, check the pulse rate, the color of the mucous membranes, as well as examine him or her for any physical evidence of fluid buildup in the abdomen or extremities. Other diagnostic tests that are useful when attempting to pinpoint or rule out heart disease include:
Chest X-Rays: These pictures allow the veterinary cardiologist to assess your pet's heart and lungs and also provide information that can help tell the doctor whether or not your pet is suffering from congestive heart failure.
Electrocardiogram (ECG or EKG): This test records the electrical activity of the heart and can tell whether heartbeats are normal or not. An ECG has a recognizable pattern showing the 'peaks and valleys' of the heart's activity. Each point on the tracing depicts how well each specific part of the heart is doing its job. An ECG also provides valuable information about a suspected arrhythmia.
Cardiac Ultrasound (Echocardiogram): This test allows the visual examination of the interior of the heart, its valves, and its surrounding structures via ultrasonography. It is a sophisticated diagnostic tool which, when combined with other components of a complete cardiac workup 'can provide veterinary cardiologists with a complete diagnostic picture of your pet's illness and help outline a treatment course for him or her.
Doppler Echocardiography: A more advanced form of ultrasonography, this sophisticated technology can enhance the diagnostic information gained from standard two-dimensional ultrasounds. In short, sound waves are bounced off of moving red blood cells in order to determine the movement and force of blood flow within the heart. There are three types of Doppler ultrasound: continuous wave, pulsed wave, and color flow. Each type is helpful in diagnosing and/or assessing the severity of different types of heart problems.
Holter Monitor: This is a 24-hour continuous ECG recording that can provide information about heart activity while the pet is at home and engaged in normal activities. The pet wears the monitor in a specially fitted vest.
Blood Pressure Monitoring: Your pet's blood pressure can be checked and monitored in much the same way as is done in people.
