Quadripolar Catheter
A cardiac catheter with four electrodes arranged in pairs for precise electrophysiological recordings and stimulation.
Full Definition
A specialized intracardiac catheter equipped with four electrodes (typically arranged as two bipolar pairs) that enables simultaneous recording and pacing from multiple cardiac sites. The quadripolar design allows for more accurate localization of arrhythmic substrates and better discrimination of local electrical activity compared to bipolar catheters. These catheters are essential tools in diagnostic electrophysiology studies and are commonly used for His-bundle recordings, coronary sinus cannulation, and right ventricular apex positioning during EP procedures.
Usage
Usage note: Often abbreviated as 'quad' in informal clinical communication, but should be spelled out in formal documentation.
In Context
- "The quadripolar catheter was positioned at the His bundle to record both proximal and distal electrograms simultaneously." — EP procedure report
- "Ensure proper electrode spacing is documented when using the quadripolar catheter for coronary sinus mapping." — Clinical protocol
