Electrophysiology Catheters

Electrophysiology catheters are specialised Millar Mikro-Tip Catheters, which are designed to be used with compatible stimulators/amplifiers (purchased separately) to perform standard electrophysiology studies. Depending on the features of the stimulator/amplifier, pacing and recording protocols can be performed from inside the heart (intracardiac) or through the esophagus (transesophageal) to determine electrical properties of the atrium and the ventricle, which include:

• Conduction times
• Refractory periods
• His potentials
• Sinus and atrioventricular nodal properties
• Inducibility of abnormal heartbeats

Compatible hardware include any ADInstruments Bio Amp for recording functionality only or a compatible stimulator/amplifier for both stimulation and recording functionalities. EP catheters also require a certain level of care to ensure accuracy and the anticipated lifespan of your catheters. Tergazyme (Alconox, Inc.) is required for cleaning and ensuring the removal of proteinaceous soils, tissue, blood and body fluids from the catheter. Please refer to Alconox, Inc.’s website to purchase from your local supplier. For a few best practice tips to help get you started with your catheters, see our guide here. Additionally, the purchase of an ESD Adjustable Wrist Strap w/ 10’ Coil Cord (Blue, 4mm Snap) is highly recommended to protect these catheters from electrostatic discharge (ESD) damage during handling.

Accessories (purchased separately):

• EPR Catheter Interface cable (5 ft), for connecting the catheter to any ADInstruments Bio Amp for recording
• EPR Catheter Interface Cable (Redel, GND, 3 ft), for connecting the catheter to an Intracardiac Electrophysiology Stimulator/Amplifier for recording or stimulation
• EPR Connecting Cable (Redel to Redel, 3ft), for further extension between the stimulator/amplifier and the electrophysiology catheter if required
