SurgiVet® ECG Leads & Cables are now sold separately enabling the lead wires to be replaced without requiring a new cable. Cables and leads are available in a 3 or 5 lead configuration. SurgiVet® monitors may use 3 or 5 leads by selecting the lead configuration in your monitor menu. Note: V9230 Basic Advisor is 3 lead only. Do your alligator clips need replacing? We can replace alligator clips on your existing ECG leads. Contact us for further information.
