Pro-padz Optimized for procedures in the electrophysiology lab, catheterization lab, OR, radiology suites, ED, and CCU Cardiology Specialty Multi-Function Electrodes, with a low viscosity gel that provides the best skin coupling, are designed to virtually eliminate dermal damage in special procedure areas of the hospital. Radiolucent Multi-Function Electrodes are designed to provide an unobstructed view of the coronary arteries during x-ray studies. Available in solid or liquid gel. Biphasic Multi-Function Electrodes are part of the complete Rectilinear Biphasic™ system —ZOLL's breakthrough technology—proven to achieve superior results in cardioversion of atrial fibrillation. Lower energy levels combined with the unique liquid gel technology virtually eliminate post-procedural dermal damage. Sterile Multi-Function Electrodes, with a unique two-pouch system that allows placement of the posterior electrode prior to surgery, are optimal for use in the operating room. They are also available with 10-foot (3-meter) lead wires. Pacing Only Electrodes are long-term pacing electrodes proven to work with ZOLL's patented 40 msec pulse duration pacing, providing the lowest mean capture thresholds and highest capture rates.
