Electrode configuration may optimize atrial sensing in floating catheters; leaves open benefit for single-lead VDD pacing.
Does the type of multipolar floating catheter affect the quality of atrial electrograms and determination of atrial depolarization direction in patients in sinus rhythm?
Floating multipolar whole ring and half-ring electrodes provide high-quality atrial electrograms and activation sequence information, supporting their potential use in single-lead VDD pacing systems.
