The document outlines the differences between cath labs and electrophysiology (EP) labs, emphasizing that while both use similar radiology systems, their functions differ significantly. Cath labs focus on diagnosing heart conditions and monitoring anatomical structures, whereas EP labs specialize in mapping the heart's electrical system and addressing issues like arrhythmias through specialized procedures. Additionally, EP labs require more equipment and trained personnel, leading to higher setup costs compared to traditional cath labs.
