When a pet requires an electrocardiogram, we use a special transmitter to send our patient's E.C.G. over the telephone lines. A board certified consultant at Cardiopet interprets the E.C.G. readings and provides us with a diagnosis and treatment recommendations. Abnormal heart rates and rhythms can be diagnosed and changes in the sizes of the heart chambers can also be extrapolated from the results. Depending on the severity of the situation, results can be obtained immediately, within the hour, or within twenty-four hours.
