PC-Vet can be used in the exam room to screen for heart abnormalities that may cause problems before, during and after surgery. ECG screens often allow us to find defects that support follow on care. Dr. Larry Tilley, a cardiology consultant, states that no other diagnostic test, including ultrasound, can accurately determine the source of various arrhythmias and conduction abnormalities as is done with ECG testing. For difficult cases, the ECG printout can be emailed directly to a cardiologist for quick interpretation to determine the necessary course of action.
