The heart and blood vessels fail in ways that are invisible from the outside and\noften silent until they're catastrophic — a narrowing coronary artery, an\narrhythmia, a leaking valve. Cardiovascular technology exists to make those\nproblems visible and, increasingly, to help fix them: capturing the images,\ntracings, and pressures the cardiologist needs to diagnose, and assisting in the\ncatheter-based procedures that open arteries and implant devices, often while the\npatient's life is on the line. The cardiovascular technologist is the hands and\neyes at the bedside and in the cath lab — running the equipment, capturing\ndiagnostic-quality data, recognizing the rhythm that means trouble, and supporting\ninterventions in real time. Without them, the cardiologist has neither the images\nto diagnose nor the support to intervene.
