This goes hand in hand with the preanesthetic laboratory testing.  Again, some information can be derived from a physical examination of a pet, but the electrocardiogram is far more accurate at assessing the rate and rhythm of a pet's heart.  Our ECG's are transmitted over the telephone to a cardiologist in New York who assesses the pet's ECG and then let's us know if they are suitable for anesthetic.  Again, if abnormalities are detected, a procedure may be postponed or even cancelled.  This is another valuable service offered to pet owners.
